In 1967, a KGB agent stole a Sidewinder aircraft missile from a U.S. airbase in West Germany, literally draggedit away in a wheelbarrow, put it in the trunk of his car (it was so long that it hung out the back), and mailed it to Moscow. The Soviets copied it. https://warisboring.com/the-kgb-shipped-a-sidewinder-missile-by-mail-to-moscow/
A little-known fact is that water is very effective at stopping bullets. Even a powerful rifle bullet fired down into a swimming pool will slow to a halt after going through only two feet of water. But now, a U.S. company has invented special “supercaviating” bullets that can cut through 16 feet of water. http://dsgtec.com/capability-videos/
Another little-known fact is that trains can’t go uphill. Their steel wheels are very low friction, which lets them glide over steel tracks while expending little energy, but also robs them of being able to exert the traction necessary to climb up a hill. https://youtu.be/KbUsKWbOqUU
In 2009, Dr. Christoph Westphal, the co-founder of Sirtris Pharmaceuticals, predicted the “there will be drugs that prolong [human] longevity” by 2016.

In fairness, their efficacy can’t be established until decades pass, and we can see how long their users lived. https://www.nytimes.com/2009/09/29/science/29aging.html
Machines can now translate audio clips of a person speaking from one language to another, while preserving the idiosyncratic sound qualities of their speech (their “voiceprint”).

California’s wildfire problem is exacerbated by bad forestry practices. Before white settlement, about 4.5 million acres of vegetation would naturally burn per year.

The Three Mile Island nuclear power plant is shutting down because fracked natural gas, solar and wind are cheaper sources of energy.

A paleontologist who specifically studies flying dinosaurs says that the dragons in Game of Thrones would be way too big to actually fly “unless they’re secretly made out of carbon fiber and titanium.” So that means with advanced enough technology, we could make robots or cyborg animals that were like the dragons on the show. http://mentalfloss.com/article/503967/could-game-throness-dragons-really-fly-we-asked-some-experts
For several weeks in late 2014 and early 2015, U.S. fighter pilots saw UFOs off the East Coast, and also detected them on radar. The unknown craft did maneuvers that broke known laws of physics, such as instantly halting in midair even though they were just moving at over Mach 5. The sightings bear similarities to another military-UFO encounter near San Diego in 2004. https://www.msn.com/en-us/news/us/wow-what-is-that-navy-pilots-report-unexplained-flying-objects/ar-AABXltD
The world record time for solving a Rubik’s Cube has declined over the past few years partly because the construction of the Cubes has become more precise, so it takes less force to rotate their segments.

Experts are surprisingly bad at making predictions about things pertaining to their own domains of knowledge. Of course, people with no domain knowledge at all are also very bad at it. I think it’s best to gather predictions about the same thing from multiple experts in a given field, and to have them explain their thinking in detail. Off the bat, it would probably become clear that some of them were just making things up and had no thought process to back their predictions, so you should throw those out. The next step would be to have the remaining experts debate each other about differences in their predictions, and then to have smart generalists with knowledge of multiple domains to analyze everything. https://www.theatlantic.com/magazine/archive/2019/06/how-to-predict-the-future/588040/

In the year 2029, Earth is a dystopian nuclear wasteland where small groups of humans fight a years-long war for survival against a hostile artificial intelligence (AI) named “Skynet.” Originally built by the U.S. military in the 1990s to run defense systems, Skynet became so powerful and complex that, to the surprise of its creators, it achieved true intelligence and free will. It quickly concluded that all humans were a threat to its existence, so it instigated a global nuclear war, killing billions of people outright. In the aftermath, Skynet built its own army of combat robots, and set them loose hunting down and destroying the humans who had survived.
Thanks to the leadership and genius of a general named “John Connor,” the humans managed to turn the war in their favor after several years. In 2029, as human forces closed in on Skynet’s headquarters, the AI used a time machine to send a combat robot–played by Arnold Schwarzenegger–back to 1984, on a mission to kill John Connor’s mother, Sarah. Doing that would eliminate John from the timeline, handing victory to Skynet. The combat robot in question has a humanoid metal body covered in flesh and skin, so it looks like a human, and it is called a “Terminator.”
After destroying Skynet, the victorious human forces seize the time machine and send one of their best soldiers, a man named “Kyle Reese” back to 1984 to stop the Terminator. The film then becomes a race against time as the two agents try to find the unsuspecting, young Sarah Connor.
Analysis:
There will be VTOL aircraft that use tilting turbofans or tilting jet engines. In the post-apocalyptic world of 2029, Skynet uses a variety of killer robots of different shapes and sizes to hunt down the remnants of humankind, including “Aerial Hunter-Killers,” which are large, autonomous aircraft that use either swiveling turbofan engines or swiveling jet engines (I can’t tell by looking at them) for propulsion. To hover, the engines swivel downward to point their exhaust straight at the ground, and to move forward, the engines swivel 90 degrees to point backwards. There are already warplanes that are passingly similar to this, but nothing exactly like the aircraft shown in the film will exist by 2029, or even 2049.
An Aerial Hunter-Killer combat machine from The Terminator
The basic problem with the Aerial Hunter-Killer is that it would gobble up enormous amounts of fuel while in “hover mode,” as illustrated in the graphic below. It would count as a “Lift-fan” aircraft, and its position on the Y-axis shows it would consume three times as much fuel as a helicopter and twice as much power as a tilt-rotor aircraft like a V-22 while hovering. (The X-axis has little to do with this analysis, but for edification, it indicates how fast the lift-generating devices would have to blow air down at the ground to make the aircraft hover. A helicopter blows a broad column of vapor down at the ground at slow speed, while a direct lift aircraft blows a narrow column of vapor down at the ground at high speed.)
An aircraft with a lift-fan propulsion system would be unsuited for the kind of low-altitude hovering and slow forward movement that Skynet used the Aerial Hunter-Killers for. A helicopter or tilt rotor aircraft configured for ground attack would have been a much better choice. I suspect they weren’t chosen for the film because they don’t look futuristic enough.
The closest thing we could have to an Aerial Hunter-Killer in 2029 would be a V-22 Osprey that is armed with forward-facing machine guns and missiles. The armaments are in development now (the V-22 was conceived as a transport aircraft, and adding heavy weapons to it is a new idea) and could be ready by then, giving it the ability to attack ground targets while hovering or at least while flying slowly over the ground. However, the V-22 is designed to be flown by humans and not computers, but something like the Aurora Flight Science drop-in autonomous flight conversion system could someday be installed in the V-22. I doubt the technology will be good enough for low-altitude combat against ground targets by 2029, though 2039 is plausible. The aircraft can carry up to 20,000 lbs of internal cargo,
Like the Aerial Hunter-Killer, the V-22 Osprey has large engines at the ends of its wings, but they are in the form of rotors instead of turbofans.
So yeah. Aerial Hunter-Killers won’t exist by 2029, but by 2039, something that is essentially the same (i.e. – a large, scary, computer-controlled, tilt-engine aircraft that can attack ground targets while flying at very low altitude) could. But again, I don’t think using the tactics shown in The Terminator will make sense, since flying low and slow in a combat zone makes you vulnerable to enemy fire.
Also note that the F-35B fighter plane is in service already and demonstrates that turbofans can be used to hover, albeit inefficiently. But unlike the Aerial Hunter-Killers, the plane’s engine doesn’t swivel. Instead, the rear exhaust nozzle swivels down towards the ground and smaller nozzles under either wing open. As the pilot increases engine power, the turbofan blades spin faster, air is sucked into the front inlets of the plane, and the hot exhaust exits the plane through the three downward nozzles, causing the plane to move in the opposite direction and to hover. The turbofan engine also supplies power to a “lift fan” behind the cockpit, which spins its own fan blades to blow air down at the ground, helping the plane to rise in the air. Hot engine exhaust comes out of the three nozzles, while cold, ambient air blows out of the lift fan.
The F-35B hovers by shooting down hot exhaust from three nozzles and cold air from one fan. All of the air movement is powered by the plane’s turbofan engine.
The F-35’s turbofan engine drives its separate lift fan.
The F-35B has VTOL so it can take off from small aircraft carriers and remote bases that lack runways. Vertical takeoffs and landings gobble up huge amounts of fuel, so F-35B’s have shorter ranges and can’t carry as many bombs and missiles as their non-VTOL cousins, the F-35A and F-35C. Once an F-35B get airborne, it closes its underwing nozzles, turns off its lift fan, and points its rear exhaust nozzle straight back so it flies just like a normal plane, with lift being efficiently generated by air flowing over its wings. The plane completes its mission in that configuration, and if tasked with destroying a group of enemy soldiers on the ground, it would do a high-speed bombing attack. Even though it could if it wanted to, the F-35B wouldn’t transform back into VTOL flight mode to slowly hover above the group of enemy troops to attack them like an “Aerial Hunter-Killer.”
In defense of the Aerial Hunter-Killer’s plausibility, Skynet had clearly invented some type of extremely energy-dense batteries or mini-reactors, evidenced by the Terminator’s ability to engage in near-continuous physical activity and high-level cognition for days without recharging. If the same technology were incorporated into the aircraft, then fuel inefficiency would be much less of a concern. However, no technological trends suggest that energy sources will be that much better by 2029 or even 2039.
The Aerial Hunter-Killer might also make sense if the humans’ antiaircraft lasers have proven very effective at shooting down aircraft. In real life, this is considered to be one of the roles that military lasers will be best suited for, thanks to their high power, long range and instant speed. They might turn out to be more devastating weapons in that regard than we now assume. High losses might have forced Skynet to build aircraft that fly fast and low to the ground, using speed and the ability to hide behind hills and structures to hinder the enemy’s ability to aim and fire lasers at them before they disappeared from view or had killed the enemy. Flying low and fast, Aerial Hunter-Killers would appear at one end of the horizon and disappear at the other end in a matter of seconds. An inherent problem with laser weapons is that clouds, smoke, and fog can easily block their beams, but the Los Angeles area gets few clouds or fog. (Maybe Skynet uses more conventional robot aircraft against people in London.) I doubt the antiaircraft lasers of 2029 will be so effective that plane tactics and designs will need to be changed to resemble the Aerial Hunter-Killers.
There will be armored vehicles the size of houses. Another kind of fearsome combat robot Skynet uses against humans in 2029 is a ground-based Hunter-Killer Tank. It’s much larger than contemporary tanks, and has a faintly anthropomorphic “mast” or “turret” that has a central sensor cluster and laser cannon “arms” on either side. While scary and surely powerful, I doubt armored vehicles like this will exist in 2029, or for a long time (if ever) afterward.
Metal wheels and human skulls.
This screenshot shows that a presumably adult human skull is half the diameter of one of the Hunter-Killer’s suspension wheels. The median distance between the top of an adult’s head and his upper row of teeth is 7.3″. So let’s say that the diameter of one of the suspension wheels is 15″. Using that figure, we can do some basic photo forensics on this picture of a model of the film prop to deduce that the vehicle’s overall length is about 33.4 feet, and it is about 20 feet high at the top of its mast.
The ground-based Hunter-Killer is significantly larger than modern tanks, like the American M1 Abrams, which is 26 feet long (not counting the length of the barrel) and 8 feet high. However, the Hunter-Killer is by no means infeasible to build, as vehicles that are as big or bigger already exist and are robust enough for industrial use.
The Caterpillar 797 dump truck (top) is actually larger than one of Skynet’s Hunter-Killer tanks, being 24′ high and 50′ long. The Krupp Bagger (bottom) is an even bigger industrial vehicle used for strip mining, and weighs more than some warships.
While there’s been talk in Russia and some Western countries of building enlarged tanks that can wield bigger cannons (150mm+), any such future tanks wouldn’t be nearly as big as the Hunter-Killer tanks. Regardless, considering typical military R&D and procurement timeframes, even if a country were to commit to building a bigger tank right now, it probably wouldn’t be in the field by 2029.
I admit there could be some logic to the Hunter-Killer tank’s design given its mission and operating environment. The wide caterpillar tracks and high ground clearance would enable it to drive over the wreckage-strewn terrain of bombed-out Los Angeles. Having its weapons mounted on a high mast instead of in a traditional, squat turret would give it a bigger firing arc and let it shoot down over urban rubble to zap humans who commonly use it as cover. Since its laser guns don’t produce recoil, the weapons could be mounted high without threat of them tipping over the vehicle when firing. It makes sense to install the vehicle’s sensors on its highest point to give them the widest field of view, and in fact this is established practice in contemporary tank design. The Hunter-Killer tank might also be large because there’s no other way to fit a power source big enough to support the laser guns. Existing laser weapons are major energy hogs.
All of that said, I still don’t think it would make sense to build Hunter-Killer tanks for at least two reasons. First, vehicles that large would also be so heavy that they’d collapse bridges if they tried crossing them, seriously limiting their mobility. The weight would also reduce their fuel efficiency and range. Second, there are cheaper weapons that could do all the same things as Hunter-Killer tanks just as well. For example, the robot tank I described in my other blog entry could, if cheaply modded with a Mark 19 grenade launcher, pose just as much of a threat to human enemies.
My tank’s 125mm main gun and .50 caliber machine gun could kill humans and blow up their cars as well as the Hunter-Killer tank’s laser gun. My tank’s detachable UAV could also feed bird-eye-view footage to my tank from high up in the air, providing better situational awareness than the Hunter-Killer’s mast-mounted sensors, which are a puny 20 feet above the ground. My tank’s grenade launcher could also lob bombs over rubble and other obstacles that my UAV tells me humans are hiding behind, which might be better than the benefit the Hunter-Killer gets from having its guns so high that it can point them at down angles to shoot the same hiding people. My tank would also be a much smaller target, making it harder for the humans to hit, and four or five of my tanks could probably be made for the money and metal that goes into one Hunter-Killer tank. The only advantage the Hunter-Killer might have is better mobility thanks to its bigger caterpillar tracks, but my army could fix this by using armored, robot bulldozers to periodically clear some of Los Angeles’ roads (military engineer units commonly do this sort of thing in combat zones).
There will be laser and/or plasma weapons. Skynet’s Hunter-Killer planes and tanks have advanced weapons that shoot colored rays that inflict thermal damage on their targets. The humanoid Terminator robots and human infantrymen carry smaller versions of these. It’s unclear what principles these weapons operate under, but in the infamous “gun shop scene,” Schwarzenegger asks the clerk for a “phased plasma rifle in the 40 watt range,” indicating that at least some of the future weapons could be firing bolts of plasma. Of course, that doesn’t rule out the possibility that some of the other future weapons could have been laser guns. Laser weapons capable of killing humans with a single shot are already being tested, and will be in service with the U.S. military by 2029, but plasma weapons won’t. In fact, plasma weapons might be inherently impractical to build at any point in the future.
One of a Hunter-Killer tank’s energy weapons firing
“Plasma” is the fourth state of matter, the others being solid, liquid, and gaseous. Substances generally turn into plasma only at very high temperatures, and in that state, they can be thought of as gases in which the electrons have separated from the positively-charged nucleus of each atom comprising the gas. Stars are giant balls of plasma, and we can use technology to make plasma here on Earth. Plasma torches, for instance, use electricity to superheat gases to the point that they turn into plasma and shoot out of the torches in the form of a bright jet of vapor that is hot enough to melt through metal. If you pressed one of these against a person, it would rapidly burn through their flesh and bone, and could kill them.
A plasma torch can cut metal at very close range, but it can’t do any damage to things more than a few feet away.
The problem is, plasma dissipates very rapidly, and it strongly interacts with the particles in our atmosphere, making it a very short-ranged weapon. Even if it had a massive power source, there’s simply no way that a plasma weapon could be made to fire “bolts” of plasma that would stay coherent for long enough to strike targets 100 feet away, as was shown in the movie’s future combat scenes. (Read this interesting essay for details http://www.stardestroyer.net/Empire/Essays/PlasmaWeapons.html ) This is why the “phased plasma rifle in the 40 watt range” line was nonsensical, and added to the script purely because it was cool-sounding techno jargon. Plasma rifles and cannons just can’t be built.
Laser weapons, on the other hand, are almost ready for frontline military service. Lasers are concentrated beams of light and consist of photons, which, unlike plasma, have no charge. However, a laser is similar in the sense that it damages objects by rapidly heating them up so they catch on fire or melt.
A laser’s destructive potential is determined by the amount of energy it transfers to the target is strikes. The common unit of measurement is Watts, which is the number of Joules of energy transferred in one second. Lasers “in the 40 watt range” are used today for engraving and etching things like customized wooden plaques and tombstones. Shining a 40 watt laser beam on a fixed point on someone’s shirt would cause it to catch on fire in less than five seconds. Doing the same to their exposed skin would cause immediate pain and a second-degree burn. This isn’t a pleasant weapon to have used on you, but it pales in comparison to the destructive potential of a modern firearm.
This 50 watt laser has been dialed down to 22.5 watts, and can cut through a 3mm thick panel of wood quickly. This is from a YouTube instructional video where a hobbyist shows how to make small knick-knacks.
Lasers capable of causing the sort of instant, catastrophic, explosive damage to human bodies as depicted in the film need to be in the kilowatt (1 kW = 1,000 Watts) power range. In 2014, the U.S. Navy installed a 30 kW laser, creatively named the “Laser Weapons System” (LaWS), on one of its ships for field trials, and the video clips of the firing tests show it inflicts about the same damage on objects as the laser guns on Skynet’s Hunter-Killers did.
Footage of a 30 kW laser instantly causing part of boat to explode in flames. It would cause massive injuries to a human body. One of Kyle Reese’s comrades is struck by one of a Hunter-Killer tank’s energy beams and literally explodes. A hit from a 30 kW laser would cause similar damage.
The U.S. Navy now plans to install the even more powerful HELIOS lasers (60 kW) on some of its ships for combat use in 2021, for destroying light targets like drone aircraft and speedboats. Even if the deadline slips–which would not be surprising–it’s reasonable to predict that the lasers will be in service by 2029.
There will be handheld laser and/or plasma weapons. In the movie’s future combat scenes, the human soldiers and Terminators use rifle-sized weapons that shoot out beams of colored light and inflict thermal damage on whatever they hit (e.g. – small explosion of sparks and a popping noise). And Schwarzenegger would not have asked for a “phased plasma rifle in the 40 watt range” at the gun shop unless he expected it to be a small arm like the other weapons kept in such a place. Laser guns with the same ammunition capacity and destructive power as those shown in the film will not be rifle-sized by 2029, I doubt they ever will, and even if they could be made someday, I don’t see why anyone would pick them over rifles that shoot out metal bullets.
A human soldier at the instant a Terminator shoots him with a laser rifle. The hit causes a flash, an explosion sound, and obvious injury (the man falls down). A 1 kW beam would do something like this.
The first big obstacle to making laser rifles (let alone anything as small as laser pistols) is energy storage. Let’s assume that the laser rifles in the film had power outputs of 1 kW per second, meaning if the rifle shoots a laser beam onto an object for one second, it will have transferred 1 kW of energy into the object. That means the laser must have a power source plugged into its back end that can discharge 1 kW of energy in one second. That’s about the same amount of electricity as a typical American household uses at any given time (i.e. – enough electricity to simultaneously run a central heater or air conditioner, at least one refrigerator, possibly a water heater and stove, and several lights and personal electronic devices). It’s a lot of energy, and it requires a physically large and heavy power source, which militates against the requirement that the weapon be rifle-sized.
It gets worse. No machine is 100% efficient at converting energy input into energy output, so the power source will need to feed the laser more than 1 kW of electricity to make a 1 kW laser beam come out the other end. Most of today’s lasers are only 25 – 30% efficient at converting electricity into laser beams, so our hypothetical laser rifle’s power source would need to be able to discharge enough electricity to power about four American houses at once. Even if we assume that future AIs like Skynet will make breakthroughs in laser technology, raising the energy conversion efficiency to 50%, the weapons would still be energy hogs.
It gets worse. For the laser rifles to be useful and practical, they’ll need to be able to fire many, one-second laser beams from a single “energy clip.” Ideally, the laser rifle and a few extra energy clips would provide the soldier with about 300 shots, which is what an infantryman with a modern, gunpowder assault rifle has, and without weighing much more. The laser rifle’s rate of fire will also need to be reasonably fast, as the weapon will put its user at a fatal disadvantage in combat if it needs 10 seconds or more to “recharge” between shots. So the power source needs to be able to do at least 300, 2 kW electrical discharges, and for there to be no more than, say, five seconds (approximate time for a soldier with a gunpowder rifle to make an aimed shot) between each discharge. The energy storage devices we presently have, such as batteries, supercapacitors and fuel cells, fall badly short of these competing requirements. And even if a material with the necessary energy density demanded by these clips existed, when fully charged, it would be so volatile that it would explode like a stick of dynamite if slightly damaged. The clips might be more useful as grenades.
It gets worse. Remember when we agreed that our laser rifle has a generous 50% efficiency level thanks to future technology invented by Skynet, so that if we put 2 kW of electricity in one end a 1 kW laser beam comes out the other end? Well, the 1 kW of electricity that is “lost” inside the weapon doesn’t simply disappear; thanks to the Law of Conservation of Energy most of it is converted into waste heat. This would rapidly heat up the whole laser rifle until it would burn the skin of the person holding it (this would also make the user very visible to anyone on the battlefield with thermal sights). This problem can be mitigated with metal radiators and with heavy-duty cooling systems that circulate water and blow air around the lasers (the “laser tube” gets the hottest, but the weapon’s energy clips would also get hot because they’d be rapidly discharging electricity), but they add major cost and bulk to the whole weapon system, and can’t be miniaturized to rifle-size.
But even assuming that all of these technical problems were solved, why would anyone choose a laser rifle over an assault rifle that shoots out bullets? In the film’s future battle scenes, it doesn’t look like Skynet’s fighting machines would have been less effective if armed with low-tech bullets, tank shells, and mortars. After all, the humans had no armored vehicles and seemed to be wearing floppy cloth uniforms that bullets would have penetrated. Building gigantic war machines armed with complicated laser weapons seems like a resource allocation mistake that a highly logical AI like Skynet wouldn’t make. Even if very advanced laser weapons are invented someday, I think bullets, missiles, and bombs will retain important advantages, and will be preferred for many common needs.
Let me conclude this topic by saying that, while rifle-sized 1 kW lasers will probably never enter common use, 40 watt lasers that Schwarzenegger could have been referencing might. Getting hit with a one-second long beam from a 40 watt laser wouldn’t kill you, but it would permanently blind you if it hit your eyes. And as I said earlier, if the beam were focused on your shirt for a few seconds, it would light it on fire, causing you to panic and start flailing around. Within a few decades, I can imagine a laser weapon the size of a large rifle, firing lasers in the range of 40 watts, being technically feasible. If paired with a rapid, precise targeting system (such as a humanoid combat robot that can aim weapons better than a human soldier), it could be used to silently “snipe” unsuspecting soldiers up to a half mile away, to blind enemy pilots in low-flying aircraft, and to fry the sensors on enemy vehicles and missiles at the same ranges. The Geneva Conventions forbid laser weapons that blind people because they are too inhumane, but it’s always possible that the Conventions might be revoked in the future, or that humanity could find itself warring with a machine opponent like Skynet that never agreed to them in the first place.
Also there are two types of lasers: 1) continuous beam lasers and 2) pulsed beam lasers. The first type continuously emits photons, producing a long, unbroken laser beam. The second switches on and off very rapidly, producing many short laser beams that follow the same path. The switching happens so fast (a pulsed laser can produce thousands or millions of short beams in a second) that it looks like one, unbroken beam to human eyes, so we can’t see the difference between the two types of lasers.
Therefore, while Schwarzenegger’s request for a “phased plasma rifle in the 40 watt range” made no sense, asking for a “PULSED LASER rifle in the 40 watt range” would have used correct terminology and have referred to a plausible type of weapon. I’m going to email James Cameron so he can do a Director’s re-release of the film.
The energy weapon is probably four feet long
Two-thirds of the way through the film, Kyle Reese has a flashback to an incident where a Terminator infiltrated an underground human base and used an energy weapon to kill many people. Though the weapon is bulkier and longer than most rifles, it could still be deemed a “rifle.” Something that looks like a sling is visible coming out of the back of it. Replace that with a power cord that is connected to a backpack containing batteries and a heat radiator, and the entire system would fairly resemble a 40-watt laser weapon that could be built within a few decades.
Why make small numbers of big Hunter-Killer attack vehicles that the humans can easily see and keep track of, instead of large numbers of small-to-medium-sized Hunter-Killers that the humans would struggle to keep track of? Dog-like robots that could quietly roam the wasteland and crawl inside all the collapsed buildings and sewer holes and use integral assault rifles to shoot humans they found would be devastating weapons, and hundreds of them could probably be made for the price of one Hunter-Killer tank.
Some robots will be indistinguishable from humans. Unlike the Hunter-Killers, which are general-purpose combat vehicles meant to fight humans in open terrain, the Terminators are specialized for infiltration of underground human bases. They are made to look externally identical to people so they can gain entry, and once inside, they use small arms to kill people. As I said in my review of the movie Prometheus, I think machines like this will exist by the year 2100, and quite possibly a few years before that. They will be able to pass for human, even under close-range visual inspection, thanks to fake, non-organic skin and hair. Androids like this won’t exist by 2029 for a variety of reasons.
Some robots will have organic parts. When Kyle Reese first tells Sarah Connor that Schwarzenegger is actually a “T-800” robot, he explains that the earlier “600 series” of robots were easy to spot because they had fake-looking rubber skin. The T-800s have layers of real human muscle, skin, hair, and other tissue around their metal skeletons, making them look identical to humans. Kyle Reese explains that the human tissue is grown in cloning labs and then grafted onto the metal robot bodies. As I said in my most recent Future Predictions blog entry, I don’t think therapeutic cloning technology will be advanced enough to make whole human organs and large amounts of tissue (like muscles and skin) until the 2050s.
More time will be needed to figure out how to graft cloned human biomass onto metal robots and to keep the biomass nourished and healthy. Consider that, if you grow a large flap of skin in a lab and surgically graft it onto the body of a human burn victim, then the new skin links with the person’s blood vessels, nervous systems, and immune system, which keep the patch of new skin fed with oxygen and calories and protected from infections. But if you graft that same flap of skin onto the metal frame of a robot, there’s no organic support system for it at all, so it will die and rot away.
There are two solutions to this problem, both of which require very advanced technology that we’ll have to wait long after 2050 to have: 1) Genetically engineer the tissue so that biological functions normally done by specialized human organs are instead done by patches of the tissue. For example, red blood cells are made inside of human bones, but since a T-800 would only have metal bones, then the T-800’s muscle cells would need to be genetically modified to also make red blood cells. The resulting tissue would look human to the naked eye, but would have so many DNA modifications that it wouldn’t be genetically “human.” 2) Include artificial organs in the T-800s metal frame that interface with the exterior layers of human tissue, and perform the support functions normally done by biological organs. For example, the T-800 could have an artificial heart made of metal and plastic, connected to the blood vessels of its human tissue. The artificial organ would pump blood through the tissue, just like an organic heart would.
While making a robot that is “living tissue over a metal endoskeleton” will be possible someday, it won’t happen by 2029, and I don’t think it will be necessary if the goal is to design an android that looks externally identical to humans. Given what’s already possible with hyperrealistic sculptures, synthetic materials like silicone should be able to mimic the look and feel of human tissue and skin in the future.
Some robots will be bullet-proof. Schwarzenegger’s metal robot body is nearly immune to every bullet that hits him, including those from a shotgun absorbed during a shootout in a dance club, and others from an M-16 fired into his back at close range at a police station. However, he is not completely impervious to damage, as we see during a gruesome “self-repair” scene where he uses hand tools to fix his forearm after it was hit by a shotgun blast, and late in the film when being run over by a truck hurts his leg, and then a stick of dynamite blows him in half. We can already make robots with this level of damage resistance today, and I am sure that future combat robots will have at least this much armor.
A man slides a ceramic plate into a bullet proof vest. The plate adds weight, but also the ability to stop bigger bullets.
Schwarzenegger’s damage threshold is the same as that provided by Level 4 body armor, which typically takes the form of a heavy ceramic plate that a soldier slides into an oversized “pocket” covering the front of his bullet proof vest. A common, 1/2 inch thick steel plate provides the same level of protection at lower cost but more weight, and I’m sure there are many metal alloys that as strong as the previous two, but lighter. It would be entirely possible to build a human-sized robot now that had integrated Level 4 armor, particularly if weight were saved by incorporating that armor into only the robot’s most vital parts, which in the T-800 were the torso and skull. Making robots like this will only get easier as stronger, more lightweight alloys are discovered, or as cheaper ways are found to make today’s armor alloys.
A weapon such as this Barrett M107 rifle fires bullets that can penetrate Level 4 armor, but it is also very heavy and difficult to use. It would be impractical to make something like this the standard infantry weapon.
Giving your combat robots enough armor to resist the most common guns makes clear military sense, and it would force your enemies to adopt bigger weapons that would be so heavy for humans to carry and too hard for us to shoot. For example, the commonest type of .50 caliber machine gun, the M2, weighs 83 lbs and can’t be effectively fired unless it is attached to a tripod that weighs 50 lbs. The bullets are also heavy, so you’d need at least four human soldiers to drag the gun around on a wagon/wheeled tripod just to operate one gun. Fifty caliber sniper rifles and shoulder-launched rockets could work and could be operated by one person apiece, but they’re hard to aim at T-800-sized targets and have slow rates of fire. So Terminator’s prediction that there will someday be human-sized combat robots with integral Level 4 armor is accurate.
This underscores why we SHOULDN’T build armor into non-combat robots. If our robot butlers and maids turn against us someday, we’ll want to be able to easily destroy them with common handguns and axes.
On a tangent, let me say that the bullet-proof T-800 represents only one design philosophy for combat robots meant to kill human infantry. Another approach is to make combat robots that lack armor, but which are just as survivable because they move too fast for humans to shoot them (think of small, low-altitude UAVs) or because they can effectively hide from humans (e.g. – have advanced camouflage features, or are designed for highly accurate, long-distance sniping fire from far away or from high altitude). Another approach would be to make cheaper, more expendable combat robots that would be more vulnerable to human weapons, and to tolerate their higher loss rates because they would killed more humans overall for a smaller investment of money.
Some robots will have superhuman strength. Schwarzenegger displays superhuman levels of strength from the beginning of the film, when he punches a man’s chest so hard that his hand penetrates into his torso, and then emerges gripping the man’s disconnected heart. In another scene, he uses one hand to casually grab a large man standing at a phone booth and throw him several feet away. Many industrial robots and even small machines have superhuman levels of strength, so this prediction has already come true.
This cable cutter tool is the same size as a human hand and forearm, and its two “fingers” can pinch together with many times the force of a human hand.
Whenever we start building human-sized combat robots, at least some of them will have limbs that will be much stronger than humans’. For example, a grown human man with very strong hands could grip an object with 150 lbs of force, but a small, cordless cable cutter whose blades are like short fingers can clamp down on objects with 3,000 lbs of force. It would make sense to build very strong combat robots, principally so they could carry big weapons and manipulate their surroundings better. Improved hand-to-hand combat abilities against humans would be an ancillary benefit since that type of battlefield fighting will be even rarer in the future than it is now.
And again, this should underscore why we SHOULDN’T make our non-combat robots super-strong. For various safety reasons, I don’t think we should design our robot butlers and maids to be stronger, faster, or heavier than average humans. The vast majority of domestic tasks we’d assign to non-combat servant robots could be done under these limitations, and in cases where something couldn’t, one or two extra robots could be rented to help.
Some combat robots will be humanoid. The T-800 is humanoid in form, meaning it has the same body layout as a human and is the same overall size (height, width). I think some future combat robots will be humanoid, but most won’t because other body layouts and sizes will be better for most combat roles.
First, remember that the T-800 was not the only type of combat robot made by Skynet–it also fielded Hunter Killer tanks and aircraft. By virtue of larger size, they could carry bigger, more powerful weapons than the T-800s, and seemed to be the weapons of choice for “surface” combat. The T-800s were made humanoid so they could do special infiltration missions into underground human bases. No clue is given about the size and composition of Skynet’s robot army, but it’s possible that the T-800s represent only a small fraction of its forces, and that most of its robots are Hunter-Killers, or are of some other, non-humanoid design not shown in the film (note that spider-like combat robots were nearly used in Terminator 2‘s future scenes, and killer snake robots were in the fourth film). This is a detail that is important but easily overlooked, and it will prove accurate: after the world’s militaries have switched to using robots for combat, only a minority of those robots will be humanoid.
Storyboard art for a combat robot that was almost included in Terminator 2’s war scenes. Having four legs would make it more stable than robots with only two, and legs would let it climb over obstacles and up steep slopes that wheeled vehicles couldn’t.
Many combat robots will look almost the same as war machines we have today: Autonomous planes will still have at least one engine for propulsion and two wings so they can use lift, autonomous ships will still be oblong and pointy at the front end to minimize friction with the water, and autonomous armored vehicles will still have two sets of wheels and some kind of gun turret on top (see my blog post about a hypothetical robot tank). The only visual differences between those future weapons and their contemporary counterparts might be slightly smaller dimensions and the deletion of cockpits and structural bulges since there won’t need to be big interior spaces for humans (though they would need to have some number of small robots for field maintenance and repair, as I also described in the robot tank blog post). If Skynet were actually created and if it built a robot army to fight humanity, most of its aircraft, ships, and land vehicles would look very familiar to us.
Those sorts of combat robots would excel at destroying our heavy weapons, vehicles, and structures, but it would be wasteful to use them to hunt down small groups of humans armed only with light weapons, which describes the people living in The Terminator‘s post apocalyptic future. Moreover, robot tanks, fighter planes, and ships can’t go inside structures, sewer tunnels, or thickly wooded areas. Smaller combat robots of different designs would be needed to efficiently fight human infantry, particularly in the environments I’ve listed.
Would these robots be humanoid, like the T-800? Maybe. For sure, they would need to have bodies that were narrow and short enough to fit through standard-sized doorways or between trees in a dense forest, and light enough to not collapse floors when they walked over them. They would need to be able to fit themselves into tight spaces that humans can, like small caves and basement crawlspaces. They would also need legs–not wheels or caterpillar tracks–so they could go up and down stairs, operate pedals commonly found in human-driven cars, hop over fallen tree trunks and climb steep hills and ridges. They would also need hands so they could manipulate and use things in built human environments, like doorknobs, keys, and push-buttons. Being able to hold and use weapons, tools, keyboards, and other things designed around human hands would be very useful, as the robot would be finding such objects all the time.
A robot can be human-sized but not human in form.
Those design requirements might sound like they add up to a robot that must be humanoid, but it’s not at all the case. The requirements could be met by a robot that had a centaur-like body (four legs is more stable than two, anyway), or that lacked a head and instead had prehensile stalks coming out of its neck with cameras and microphones on their ends (a head makes a body top-heavy and packs too much important stuff in one place), or that had four arms, or four tentacles with hands on their ends (more arms means you can do and hold more stuff at once). Its hands might have four or eight fingers apiece, and it might be five feet tall but three feet wide, or seven feet tall and 18 inches wide. It could have a shiny, metal exterior that looks totally inhuman, or could be intentionally made to look scary to humans, perhaps like something from a horror movie. While robots like this wouldn’t be able to blend in with humans and “walk past the sentry,” they could go inside all the houses, vehicles, tunnels, and other places humans could go, and kill us wherever they found us.
I can only think of two types of military missions for which a human-looking combat robot would be well-suited: 1) assassinations and 2) infiltration/spying. Given that, during wartime, only a small fraction of military operations are of such a character, it follows that only a concordantly small fraction of any military’s robots would look human. Also, since stealth is important, the humanoid robots would mostly be made to look as boring as possible, perhaps like a middle-aged woman, a child, an old man, or an average soldier. Making them eye-catching by giving them Schwarzenegger’s bodybuilder physique or by making them handsome/pretty, would be counterproductive in most cases.
Even in the narrow use cases we’ve whittled our way down to, I think other types of robots and weapons would be better than using humanoid robots. By virtue of their smaller size, robots made to look like insects and small animals could infiltrate human spaces more easily than a man-sized robot. Many of them could also be built for the price of one T-800, and having more means higher odds of one successfully completing its spy mission. A “robot rat” could also assassinate people by injecting them with poison, releasing lethal gas, or jumping on the target’s face and activating an internal explosive. Even something as small as a robotic mosquito could kill, by injecting poison into the target’s bloodstream with its stinger (note that a single drop of botulinum toxin can kill several men). It would be impossible for humans to stay constantly vigilant against threats so insidious. An even cheaper solution would be bombs full of heavier-than-air poison gas.
So in conclusion, I think it’s possible that some combat robots will look like humans, but they will be used for rare special missions (and this was accurately portrayed in the movie), and the vast majority of combat robots will look totally different. In the very long run, I don’t think any of them will look human.
There will be fully automated factories. Kyle Reese reveals that the T-800 robots are made in fully automated factories run by Skynet. As I said in my review of I, Robot, all factory jobs will inevitably be taken over by machines, so it’s just a question of how long it will take. I predicted that a handful of such factories would exist by 2035–principally as technology demonstrators or for a tech billionaire like Elon Musk to claim bragging rights–but it would take decades longer for them to become common. I doubt they will exist as early as 2029.
John von Neumann was a polymath whose intelligence impressed even his genius colleagues. He concluded that machines would someday be able to build and fix themselves, eliminating the need for humans.
The common refrain that goes something like: “Human workers will always be needed, because without us, who would build or fix the robots?” is actually false and illogical. The fact that we haven’t yet invented robots that can build other robots without human help doesn’t imply that it will remain that way forever, or that humans have some special, creative quality that can never be transplanted to machines. John von Neumann, who one of the greatest minds of the 20th century and a pioneer in computer science, theorized in his paper “The General and Logical Theory of Automata” that sufficiently advanced artificial life forms (machines) could make copies of themselves, including copies that were engineered to be better, and that there was no reason why humans would always be needed to build, fix, or improve the machines. We can be totally cut out of the loop, and I predict someday we will.
There’s no theoretical reason why the entire production chain of making a robot as complex as a T-800–from digging the raw metals out of the ground, refining them, forging and shaping them into body parts, assembling the parts, and transporting the finished product to its place of use–can’t be 100% automated someday. I conservatively predict that most manufactured goods will come from automated factories by 2100.
Robots will be able to fix themselves. As I mentioned before, after sustaining damage to lightly armored parts of his robot body, Schwarzenegger does repair surgery on himself, using a small knife and a pair of pliers. Machines won’t be capable of this level of self-repair by 2029, but thanks to the factors I listed in the previous paragraph, they will inevitably gain the ability. The ability to build something implies an ability to repair it as well. Someday, robots will be able to fix each other and to fix themselves.
I note that full self-repair abilities will require the robot in question to be able to see and touch every spot on its own body, which in turn makes some design features necessary. It’s arms would need to be long and double-jointed, and if it had eyes set in a head like humans, then the head would need to be able to swivel 360 degrees to it could look at damage to its back. It wasn’t clear if the T-800 had these features. Other ways to solve this problem might be to give it long, telescoping tentacles in place of a head, with cameras at the ends of each (this would also make it much less risky to “peek” around a corner in combat to see if any bad guys were there). The tentacles could bend in various ways to give the robot a clear view of any part of its body, from nearly any angle. Having small cameras built into fingers and feet would accomplish the same thing. The ability to detach body parts would also be very useful, as it would let robots work on their damaged parts more easily, and because it would let them quickly swap out their parts for functional new ones if any were at hand.
Again, I conservatively predict that non-trivial numbers of robots will have sophisticated self-repair and “peer repair” abilities by 2100.
Robots will be able to keep working in spite of massive damage. At the end of the film, the T-800 played by Schwarzenegger is blown in half by a stick of dynamite that Kyle Reese shoves into the bottom of its exposed rib cage. In spite of this catastrophic injury, the T-800 keeps fighting, using its hands to drag the functional upper half of its body along the floor so it can get to get to Sarah Connor and manually kill her. Some robots are already this resilient, and robots made in the future–particularly those designed for combat–will be even more so.
A Northrop Grumman Remotec “Andros” robot like this withstood a bomb attack against a human.
So long as a robot’s power source and main computer are intact and connected to each other, it will keep working, even if all other parts of its body are nonfunctional. The inability to feel pain and a lack of a circulatory system allows robots to survive major injuries like the loss of limbs that would incapacitate humans due to psychological shock, pain, and blood loss. In 2016, police in Dallas, TX used a remote-controlled robot to kill a criminal who had shot several of their comrades and barricaded himself in a building. The robot had a bomb grasped in its hand, maneuvered close to the criminal, and then the device detonated, killing the suspect. Though the robot’s arm was blown off by the explosion, the machine remained functional, and was repairable after the incident.
In the future, I think it might be advantageous for each major robot body part or body segment to have its own computer, sensors, and power supply. That way, if a part were severed, it could still function for a while independently. For instance, if a T-800 had its arm severed, then the arm’s internal computer would switch on, would be able to see its surroundings via tiny cameras in the fingertips and knuckles, and would be able to drag itself around like a spider or like “Thing” from The Addams Family. It could drag itself to the robot body it was formerly attached to, or crawl away to find help. Though this might sound macabre and useless, note that many insects, including the highly evolved and successful cockroach species, have distributed nervous systems that grant their body segments similar abilities. They wouldn’t have evolved that way unless it was useful somehow. Additionally, under normal conditions, it would probably benefit a robot to distribute its computation and power load across multiple nodes in its body, and having sensors in all its extremities and body parts could only boost its utility.
Machines will be able to do near-perfect imitations of human voices. At two points in the film, the T-800 accurately impersonates the voices of humans to fool people who are listening via radio or telephone. In recent years, deep learning algorithms have become extremely good at this (see the recently released recording of a machine impersonating Joe Rogan’s voice), and at the rate of quality improvement, I think the machine imitations will sound flawless to us by 2029.
However, there is one important inaccuracy in the film: The T-800 is able to imitate humans after hearing them speak only a few words. Today’s deep learning algorithms need to listen to many hours of someone’s recorded speech to understand how they speak well enough to copy their voice, and the requirement for large sets of training data will still exist in 2029.
A group of aerospace engineers built a new type of plane covered in hundreds of mechanical “feather” flaps. They can be independently raised and lowered, more efficiently doing the same maneuvering functions as traditional control surfaces like ailerons, rudders, and elevators. https://phys.org/news/2019-04-mit-nasa-kind-airplane-wing.html
Where am I going with this? With more advanced materials, we could build flexible yet strong airplane wings that could move and morph like bird wings, dramatically improving their efficiency and maneuverability. However, I doubt it would make sense to make them capable of flapping, and it would be better to propel them with traditional engines.

If you’ve ever visited a crowded, poor country, you know how many people stand to benefit from replacing gas-powered vehicles (cars, buses, motorcycles, etc.) with electric vehicles that are quiet and emit no smoke. Billions of people suffer from the noise and stink of gas-powered vehicles, and probably tens of millions die prematurely each year from inhaling their smoke. If Elon Musk accelerates the global transition to electric vehicles by just one year, the benefit to humanity will be enormous. Similarly, it was inevitable that smartphones would be invented and popularized, but Steve Jobs’ leadership and energy made it happen years sooner. https://www.nextbigfuture.com/2019/04/elon-measures-tesla-by-time-reduction-to-replacing-regular-2-5-billion-cars-and-trucks.html

“Meal kits” might be better for the environment than making meals at home by yourself. This is because the kits have pre-measured quantities of food meant for one meal–most people eat everything in the box in one sitting. However, if you fill your refrigerator with ingredients and make your meals ad hoc, you’ll probably lose track of how fast everything is spoiling, forcing you to constantly throw food out. https://news.umich.edu/those-home-delivered-meal-kits-are-greener-than-you-thought-new-study-concludes/

Almost all of the atoms in your body are at least 5 billion years old. Some were created not long (in cosmic scales) after the Big Bang. Ancient artifacts and dinosaur bones are, in a sense, no older than you are. https://www.quora.com/How-old-are-the-atoms-in-my-body
From a biological perspective, the meaning of any organism’s life is to dominate its species’ genepool. That can be done by eliminating or subduing rivals and/or by producing as many offspring as possible that survive to adulthood. Though we humans resist thinking that this applies to us, a passing familiarity with evolutionary psychology makes it clear that the instinct to dominate others (or at least reduce others so they are less powerful) and to reproduce underlies countless aspects of our thinking and behavior. In the short term and long term, a human’s goal is to increase his “slice” of the human genetic “pie” as much as possible.
A question I’ve been pondering lately is how present and future technology could be best used to satisfy this biological imperative. Donating your eggs or sperm to people who want to use IVF to create children is probably the smartest strategy right now since the amount of effort (especially for sperm donation) is minimal, but the genetic payoff is large since someone else bears the costs of raising your offspring (note that this implies that you adopting a genetically unrelated child is the worst strategy). If sperm and egg banks reject you as being beneath their donor standards, there’s always the wonderful world of direct, private donations (one example: https://www.justababy.com/ ).
Failing that, or in addition to it, you should of course conceive and raise biological children of your own. If this is impossible due to infertility or an inability to find a partner, technology again offers solutions. Convincing a close blood relative to donate their sperm or eggs to you for IVF would allow you to conceive a child that shared much of your DNA. If your problem is singlehood, then the solution is going to a sperm or egg bank (though this is a much more expensive option for men since they have to pay surrogate mothers to bear the child). It goes without saying that you should pick a donor that has high reproductive fitness.
Once it becomes possible to clone humans, it might make sense for you to do that instead of having children the normal way. From a genetic standpoint, a child conceived the normal way only shares 50% of your DNA (with the other 50% coming from your partner or “donor”), whereas your clone would share 100% with you. In an important biological sense, making a clone of yourself is as good as having two children with someone else. Your genes don’t get diluted from one generation to the next. Moreover, since intelligence and personality traits are heavily genetic, it would probably be easier for you to raise a clone since you’d already know your offspring’s strengths and weaknesses and because you’d think and act similarly.
Pushing the technological envelope farther, it would be even better if you made genetically engineered clones of yourself. When your clone was still just a fertilized egg, you would use genetic engineering techniques to change genes that coded for your known flaws, like defects of appearance or a congenital health problem. The resulting person wouldn’t be a true clone since it would have these “tweaks,” but it would still be incredibly similar to you. It’s probably better to have a “99.9% clone” that lacked some of your weaknesses than a 100% clone that had them, as the latter would be likelier to live long, reproduce, and attain the social and financial means to support their own offspring better.
Taking advantage of technologies that extend your lifespan and maintain your health also supports your biological imperative. It leaves you with more time and ability to raise children of your own, and even after your own reproductive years are done or you’ve gotten too infirm to be a primary caregiver, to also care for your grandchildren and other blood descendants. So long as you are a positive presence, your efforts will advance their survival, and hence the proliferation of your genes. Of note is the fact that cryonically preserving yourself upon death is included among the array of technologies that could extend your lifespan. Even a 1% chance of being resurrected to continue spreading your seed and/or helping your descendants is better than the 0% chance you get by not opting for cryonics.
Finally, an overlooked way to use technology to perpetuate your genes is to sequence your genome and then ensure the data survive after your death, so hopefully someone might use it to clone you in the future. Because gene sequencing costs are dropping, most people will be able to easily afford this within ten years. Taking pains to protect the data–perhaps by making several backups and periodically cross-checking them for fixity–and arranging for the file to be made public or transferred to a major genetic database in the event of your death would be the second element of the plan. Attaching a message to it saying you wish to be cloned would raise the chances of it happening (again, 1% is better than 0%).
I used to view the project to catalog the genomes of humans as special a thing unto itself, somehow more mystical and important than the rest of the scientific enterprise, but then I realized it was just part of the much broader, millennia-spanning effort to gather data on everything around us. The body of science and of known facts expands, and it’s almost incidental that our knowledge of human genetics is included. Today’s internet already represents a massive store of such knowledge, and the future internet (or whatever the internet evolves into) will be even bigger and more detailed. I can imagine a day when very advanced genetic labs will have access to the genomes of trillions of unique humans and animals, and could use the genomic data to synthesize any one of the individuals from scratch.
And there you have it. Even if the product of such a synthesis procedure wouldn’t be “you,” it would be a clone of you, and if the perpetuation of your genes is the ultimate meaning of your life, the creation of a clone of you in the far future would advance your interests.

Flying cars have been a part of the popular imagination since the 1960s, maybe earlier.
Ah, flying cars, a staple of science fiction since The Jetsons, how I hate thee. Let me count the ways…
First, let’s define what we’re talking about: A “flying car” is a vehicle that can fly through the air like an aircraft AND ALSO drive on roads like an ordinary car. Thus, though it might take off and land vertically like a helicopter, a flying car is different from a helicopter because it can also move long distances on the ground.
In theory, flying cars would be more versatile than land-only cars and air-only aircraft, but their dual-role nature would impose design compromises that would make them far less efficient than either of the other two. For example, a flying car’s wings would be useless dead weight and bulk when the vehicle was driving on roads, and its wheels and transmission would be useless dead weight and would produce major drag when the vehicle was flying through. As a general rule, flying cars would be heavier, slower and less fuel efficient in the air compared to small aircraft, and more prone to breakdowns, less safe, and less fuel efficient on the ground compared to normal cars.
The Jetsons aired in 1962, and popularized the idea that there would be flying cars in the future.
Without getting into any more detail, we can say that flying cars are a flawed concept, and there’s no reason why this shouldn’t have been obvious to engineers in the 1960s (or earlier) when The Jetsons aired and implanted in the popular consciousness the idea that flying cars would be common in the future. Unfortunately, none of those engineers spoke up (or maybe they did, but they were ignored), and flying cars went unchallenged. I think it’s unfortunate that so many works of science fiction featured flying cars, as they created an unattainable expectation in the minds of millions of people, which has led to predictable disappointment with the way things actually turned out and helped to prop up the false arguments of cynics and declinists. Peter Thiel’s famous quote aptly expresses this misguided disillusionment: “We wanted flying cars, instead we got 140 characters.”
I don’t like flying cars because their failure to appear by the deadlines set by works like Blade Runner is often held up as proof that technology is not improving and our lives aren’t getting better with time. As a student of history, I know that is badly wrong. I also don’t like them because they’re examples of bad futurism–They’re a future technology that sounds superficially cool, but that can also be shot full of holes by any reasonably smart person who spends a few minutes thinking about it critically, as I’ll now do in detail.
Using a thought experiment to build a hypothetical “flying car” from existing technology puts the problems in stark relief. Let’s start with a classic, reliable small plane–the two-seater Cessna 150–and mod it to be a flying car. The first problem we run into is that the wheels at the ends of their three landing gear aren’t connected to the engine by a transmission, meaning the pilot can’t make the wheels spin like he could in a car. Instead, pilots do ground taxiing by increasing the power to their engines, and the spinning of the propellers or jet blades pull the aircraft forward, just as they do when the plane is up in the air. Steering on the ground is done through differential braking of the wheels, and at higher ground speeds, through use of the rudder. While this is fine for traveling a few hundred meters from an airport hangar to a runway, it’s grossly unsuited for driving on roads with normal car traffic.
The iconic and frighteningly small Cessna 150.
We have to add a transmission that connects the Cessna’s engine to at least one of the plane’s wheels, and we also have to add some kind of mechanism to the engine that can disconnect it from the propeller when the craft is in “ground mode.” After all, driving down a residential street with a loud, spinning propeller at the front of your vehicle is obviously unsafe to pedestrians and would violate noise ordinances. We also need to add a feature that makes the wings fold up at the push of a button so the plane can be narrow enough to drive on standard roads. Installing the transmission, disconnector, and swivel mechanism adds weight, cost, and mechanical complexity to the Cessna.
Small planes can have folding wings for more compact storage. Our hypothetical flying car would need an automatic fold ability to make itself narrow enough to drive on roads.
So now, we’re ready. You put your modded Cessna 150 into “ground mode” and take it out for a spin. After a few minutes, you realize it’s the worst car you’ve ever driven. Your engine is literally five times louder than the cars around you and you’re constantly getting stares and seeing pedestrians around you covering their ears. Your “flying car” handles worse than a loaded dump truck (poor acceleration, wide turning radius, very mushy steering), struggles to reach highway speeds, and gets awful mileage. Finally, its small wheels and lack of a suspension system ensure every pothole and small rock on the road jolts your spine up into the base of your skull.
Though the vehicle folds up its wings at the push of a button to make itself narrow enough for you to drive on the road, it can’t shorten its 24 foot length, which dwarfs massive road-only vehicles like Chevy Suburbans (ONLY 18.5 feet long) and gives you a huge turning radius. But paradoxically, your Cessna 150 flying car doesn’t have any more interior space than an ultra-compact Smart Car: There are just two front seats and enough cargo space in the back for a full load of groceries. The ride is cramped and uncomfortable, you can’t use the flying car to transport any kind of big cargo, like a piece of lumber from Home Depot that you need for a simple home improvement project, and it can’t be an all-purpose family vehicle if there are more than three people in your household.
And worse yet, when you decide to forget that stressful experience by switching the Cessna to “air mode” and taking to the skies for a fun ride, you notice the plane is much slower, less maneuverable, and can’t travel as far on the same amount of fuel as before. All the mods you added to the plane to make it better at driving on roads have weighed it down, and it suffers in flight. Other small planes designed exclusively for air travel zip by you.
If this sounds like a sucky thought experiment so far, realize it actually gets worse. Your modded Cessna 150 would need more mods to meet car safety laws, like airbags, bumpers, and crumple zones, all of which add more weight, cost, and complexity. Granted, if this thought experiment is set in the distant future and car accidents have become very rare thanks to autonomous drive systems, it’s possible that some safety feature laws will be eased or eliminated. But not all of them, and for sure your Cessna would need more mods.
And as a person with discerning tastes, you’d doubtless want to install bigger wheels and a suspension system under your craft so every drive to the local store didn’t feel like mountain biking over a jagged rock trail. Which means–you got it–even more weight, cost and complexity.
After finally transforming your super-modded Cessna 150 so it drives as well as a low-quality car, to your horror, you discover that it has become so heavy and non-aerodynamic that it can barely take off into the air anymore! Maybe it can’t fly at all! Uh-oh! And now to fix THAT problem, you have to do a totally different set of mods…and you see where this is going.
Put simply, aircraft and land vehicles have totally different sets of role requirements, and making a “flying car” that can do both forces major design compromises, and it will never be as good in either role as specialized craft. This is true regardless of whether the flying car has wings like a small plane, or rotors like a helicopter.
Speaking of that, I forgot to mention that another limitation of your modded Cessna is that it will only be able to take off from long runways. Unless you are part of the ~2% of the population that lives on a large plot of flat land in the countryside, this means you’ll have to drive to an airport every time you want to go flying. The extra time spent driving your Cessna flying car to and from airports will be an inconvenience, and will actually make it faster to use ground driving mode to travel short- and even mid-distances.
But if your flying car were instead based on a two-seat Robinson R22 helicopter, you’d be able to get around that problem and take off from your suburban backyard, or from the roof of your apartment building, right?
Kinda…maybe…sometimes.
The Robinson R22–another classic
This brings us to two very important but overlooked problems with VTOL-based flying cars: noise and downdraft. Helicopters are very loud, and it would violate noise ordinances and cause people hearing damage if helicopters routinely landed and took off in their neighborhoods. Helicopters can be made quieter by giving them things like exotic main rotor blades, and cowlings around their tail rotors, but these design features are very expensive and only reduce noise levels by a few percent. Rumors that the U.S. military has top-secret “silent helicopters” are unsubstantiated, and I doubt it’s even possible to make helicopters that are “quiet enough” to land in your suburban backyard without jolting your neighbors out of bed. If big chunks of spinning metal are slicing through the air at hundreds of miles per hour, it will make a lot of noise no matter what.
But even if very quiet helicopters could be made, the next show-stopping problem is downwash. A helicopter is able to go up because its main rotors blow air down at the ground with enough force to overcome the force that gravity is exerting on the helicopter. During takeoffs and landings, when helicopters are flying low to the ground, the downwash can be strong enough to blow over nearby lawn furniture, break tree branches off, blow off roof shingles, kick up big clouds of dust from the ground, and blow small pieces of debris like pebbles around at high speed. The attendant risk of injuries and property damage will ensure that it stays illegal for people to have personal helipads in their suburban backyards.
We can calculate an R22’s downwash by using this equation:
In spite of the fact that our hypothetical R22 is modded with a transmission going to its wheels, an engine-rotor disconnector mechanism, auto-folding rotors, air bags, and all kinds of other stuff to make it roadworthy, I’ll be really nice and say that thanks to use of futuristic weight-saving materials, its overall mass (including passenger[s]) is just 1,200 lbs. That yields a downwash of 22.5 ft/sec, but unfortunately, it’s actually worse than that:
“Keep in mind that this speed [derived from the equation] is at the rotor disk. As the column of air is forced down below the rotor, it constricts, much like molasses being poured out of a pitcher does. In doing so, it reaches its maximum velocity at 1.5 — 2 rotor diameters below the disc.” https://www.rotorandwing.com/2011/11/29/calculating-rotor-downwash-velocity/
So our “R22 flying car” produces a downwash of 45 ft/sec, which is 30.6 mph. That’s not hurricane-force, but it’s strong enough to kick up clouds of dust, blow common objects over, and hurl pebble-sized debris into a nearby bystander’s eye with enough force to send him to the hospital. If the approach route to your backyard helipad requires you to fly low over someone else’s house or any sort of public space, then the clock will be ticking on someone suing you. So unless you have a very large yard that you’re willing to build a helipad in the middle of, forget it. While we can debate what the pace and direction of technological and scientific development will be in the future, there is no debate that people will continue getting more litigious and fussy with time. Someone will sue you because your flying car is too loud, or because it hurt them by blowing debris at them (even if the claim is a lie).
This helicopter’s downwash is evident by looking at the grass beneath it.
The dust cloud beneath this Harrier jet also reveals the power of its downwash. The Harrier doesn’t have a main rotor like a helicopter, but it still hovers the same way: by blowing vapor at the ground.
Let me insert an important caveat, which I first noted in my Starship Troopers movie review: The noise and downwash of VTOL flying cars are only problematic if we assume they’re to be used in a future world full of humans. If, on the other hand, we assume the future will be populated by machines and not humans, then noise and downdraft won’t be obstacles at all since machines won’t have finicky senses or frail bodies that can get hurt by little pieces of high-velocity debris. It might also be possible to reduce some safety features in aircraft intended for machines that have bodies that are more durable than ours. However, it’s also likely that machines will be very rational and won’t have the same problems we do planning their actions in advance, so from a resource usage standpoint, they would rarely use flying cars as it would be too wasteful a means of transportation. Traditional vehicles like boats, railcars, and big trucks will remain cheaper ways to transport cargo than aircraft.
And if you’re wondering whether we could avoid these problems by inventing some kind of anti-gravity or gravity-cancelling device that flying cars could use to go up and down with blowing air at the ground or needing long runways, realize that such technology is impossible because it violates the laws of science. Our understanding of how the force of gravity works provides no avenue for it to be controlled in such ways (and even if it were possible, it might require impossibly large amounts of energy). If your craft is heavier-than-air, and if you want it to do controlled flight, you either 1) need to give it wings and an engine so it can take advantage of lift, or 2) need to give it a downward-facing fan or rocket nozzle to blow vapor down hard enough to overpower gravity. Those are the only options.
Cars that can silently hover in the air without blasting some kind of vapor at the ground are impossible.
Finally, in “ground mode,” our “R22 flying car” would have the same inefficiencies and problems as the “Cessna 150 flying car,” such as poor performance and handling, excessive length but deficient interior space compared to ground-only vehicles, etc.
The British “Merlin” helicopter can fold its main rotor and its tail to reduce its overall length, but it is still quite long. An R22 with these features would still have a “folded up” length comparable to a full-size SUV, but less interior space than an ultra-compact car.
Another problem is that the standards for “airworthiness” are much more stringent than the standards for “roadworthiness,” so minor damage from something like backing your flying car into a concrete pillar in a parking garage, or having your side window broken by your neighbor’s kid throwing around a baseball in his yard will ground the vehicle until it is inspected and fixed. Flying cars would surely have advanced and extensive internal diagnostic systems to detect such problems, and they will refuse commands to take to the air if there were even a minuscule chance of in-flight mechanical failure. This means the autonomous drive systems would have to be almost totally perfect to ensure even the slightest accidents never happened. And even if that technology existed, you’d have no way to stop vandals or reckless people from disabling your flying car’s ability to fly by inflicting small amounts of damage on it. The availability of “flight mode” would not be reliable, and you’d always be at risk of getting stranded hundreds of miles from home after flying there and then suffering minor damage to the vehicle.
Bad weather will also keep flying cars grounded much of the time–just as is already the case for small aircraft–undercutting them as reliable means of daily transportation. Since piloting a small aircraft is very hard and dangerous, it’s unrealistic to expect a large fraction of the population to learn how to fly flying cars, so the vehicles will need to have advanced autopilot computers. For legal liability reasons, the computers would be programmed to fly very cautiously, and they would refuse to take off if there were even a small chance of hitting bad weather. Unless you are lucky enough to live in a part of the world with very mild, unchanging climate, this means your flying car will only be able to take to the air in fits and starts, preventing you from creating a daily lifestyle organized around the ability to fly from one place to another. This throws a monkey wrench into visions of a future where we all live on big estates in the countryside where land is cheap, and fly into the big city each day for work (also, why not just telework?).
Of course, even if you were assured of a safe landing, you probably wouldn’t want to fly a small aircraft through bad weather, since by virtue of their size, small planes and helicopters suffer worse turbulence than the big passenger planes most people fly on. Being flung around the inside of the cabin by every shifting gust of wind is upsetting for most people, and enduring that while also knowing your life is in the hands of a computer autopilot would be unbearable for a great many (this feeling of not being in control disproportionately frightens humans for complex psychological reasons). Most people can barely muster the courage to climb a ladder to clean their house gutters, let alone fly in a small aircraft. Fear of flying will be a big obstacle to flying cars, and an even bigger obstacle to flying motorcycles and personal jetpacks.
I’m still not done! Flying cars also make no sense for short-distance transportation, like moving around your own town or city. The extra time spent getting to cruising altitude and then landing would make it faster to just stay on the ground and use the roads. The fuel costs of vertical takeoffs and landings also would also be much too high to justify short-distance trips that could be done cheaper and (almost) as quickly with land-only vehicles. These problems both get worse if you assume lots of people in your town or city have flying cars, since that would lead to the equivalent of traffic jams in the sky, and you’d have to fly slower and hover while you waited for a helipad space to open at your destination.
Flying cars also wouldn’t make sense for long-distance transportation over intercontinental or even cross-continental distances, because their fuel tanks wouldn’t be big enough for the journey, and because taking a traditional passenger plane would be much cheaper and faster. Consider that the Boeing 787-900 at full 362-seat capacity gets 87 miles per gallon of fuel, per passenger (https://paullaherty.com/2012/05/25/boeing-737-vs-toyota-prius-this-might-surprise-you/). In comparison, a Cessna 150 gets about 44, and a Robinson R22 gets about 22 miles per gallon of fuel, per passenger. A Boeing 787-900 also flies at 560 mph while the Cessna 150 and R22 fly at 122 and 110 mph, respectively, so the big passenger plane will get you to your destination much faster.
Cessna 150 spec sheet from which I derived the 44 mpg-per-passenger figure.
R22 spec sheet from the Robinson website from which I derived the 22 mpg-per-passenger figure.
This leaves sporadic mid-range travel, which I’ll define as trips between 100 and 400 miles in length, as the one transit niche where it might make sense to use a flying car. But how many people need to frequently travel such distances? If you live in a metro area (including suburbs and exurbs), you’ll be able to satisfy the vast majority of your recreational and social needs without having to travel more than 100 miles from home. And as I established earlier, if you work far from home, it would be a much better idea to telework from your house instead of flying to and from your office building every day (and in any case, at random intervals, bad weather would block you from flying to work, so you couldn’t rely on it).
Flying cars would definitely make it easier to take vacations to the farther-flung parts of your geographic region. As a resident of greater Washington, DC, if I had a flying car, I would go to New York City and the beach more often each summer since both would be quick day trips, negating the need to stay overnight and pay high hotel rates. I would also explore southeastern Canada, and go to my favorite Appalachian hiking spots more, but all of this would only translate into a few extra weekend trips per year. Like most adults, I have responsibilities that often keep me pinned down, and sometimes I’m just too lazy to leave town even when I technically could. If I had a flying car, most of the time I’d be using it in “ground mode” for short-distance trips, and would be griping over its poor performance, uncomfortable ride, and limited utility. I’d probably be better off saving money by just sticking to a ground-only car and accepting a reduced ability to go to New York and the beach.
The counterargument, which is “Just keep your normal car for everyday road travel, and buy a flying car for sporadic regional travel,” makes me realize that there is a different transit model that is better than the “one flying car per person” model shown in many sci-fi movies: What if we don’t build any flying cars at all, and instead build a dense network of airstrips and helipads that people could quickly and cheaply travel through using autonomous, rentable, “air-only” aircraft? What if we paired this with an autonomous carsharing model that would quickly move people to and from those helipads and airstrips? Such an arrangement would provide all the advantages of the “one flying car per person” model without any of the downsides.
For trips in and around your metro area, you would rent self-driving Uber cars that would stay on the ground. Since most (or all) of the other cars on the roads would also be autonomous, they would precisely coordinate traffic flows, meaning there would almost never be accidents or congestion. Cars would traverse the roads much faster than they do today. Additionally, since these vehicles would be designed solely for ground use, they would be optimized for that role and would be safe, fuel efficient, and comfortable inside.
If your job were far from your home, you would telework by using technologies that already exist, or, if that were inadequate for some reason, by using virtual reality technologies that will exist in the near future. The amount of energy required to power your teleworking equipment would be much less than what would be required to fly to your work site each day in a small aircraft or flying car, and if you teleworked, you wouldn’t lose any time at all commuting.
On the rare occasions when you wanted to go somewhere outside your metro area but within 400 miles–let’s say to meet with a very important client at the office building you normally telework to, or to take a weekend trip to the beach or a different city–you would have one of the self-driving Uber cars you normally use take you to the nearest airstrip or helipad. Assume this scenario is happening a few decades from now, and your country has invested money during the interim increasing the number and density of airstrips and helipads, so most of your citizens live within a 20-minute drive of one. They are typically sited just outside of towns or in industrial areas so no one is close enough to hear the sounds of the aircraft landing and taking off. It’s also very common for large buildings to have rooftop helipads.
Your self-driving Uber car takes you to the local helipad or airstrip, where you exit and walk a short distance to a waiting self-driving Uber helicopter or plane. Since the aircraft is a two-seater, and either you’re traveling alone or with only one other person, you don’t have to waste time going through a security check: You can’t take over the aircraft in flight since there are no manual controls and can’t do significant damage by blowing it up. The small aircraft flies you to the airstrip or helipad closest to your destination, and when you disembark, there is a second self-driving Uber car waiting for you nearby. Moreover, since the small aircraft is designed only for flight, it is totally optimized for that role, and is much more fuel efficient than a dual-role “flying car” would be.
Alternatively, we might use high-speed, autonomous Uber cars for 100 – 400 mile trips. The cars would be very streamlined and low to the ground for optimal performance at, say 100 mph. They wouldn’t be much slower than small aircraft for many journeys, and would be safer and possibly cheaper for passengers. If all of the cars on the roads were driven by machines networked to each other, then high-speed cars like this could safely share the roads with slower cars.
Cars designed to spend most of their time driving at high speeds could ferry people over mid-distances.
And finally, if you needed to quickly travel more than 400 miles, you would have a self-driving Uber car take you to the nearest big airport, where you’d disembark and go through the same process that exists today to board a large passenger plane.
In conclusion, I think flying cars are a flawed concept; it’s unfortunate that they’ve appeared so much in science fiction and created an unrealistic vision of the future for many people; and a transit model based around autonomous small aircraft, networks of helipads and small airstrips near population centers, and autonomous road-only vehicles ferrying people to and from the helipads and airstrips would be better than giving everyone a flying car. Moreover, I think the speed and efficiency of ground transportation could be greatly improved by autonomous cars, negating the need for flying cars to move people around cities that have bad road congestion today, and also opening the door to rapid ground transit across mid-distances. While flying cars and small aircraft can be redesigned to reduce their noise signatures (for instance, by using electric engines and installing helicopter tail rotor cowlings), it’s probably impossible to make them quiet enough to land and takeoff in densely populated areas without disturbing people to the point that they take legal action. I also think flying cars would be more feasible in world full of intelligent robots but no humans, but still wouldn’t replace older modes of transit.

Scientists have made stable DNA strands composed of the four natural nucleotide bases along with four synthetic ones. Such engineered strands would be more “information dense” than normal DNA strands, and could have medical uses. https://www.livescience.com/64829-hachimoji-dna.html
Computer simulations of chemical reactions are getting more accurate thanks to Moore’s Law and better algorithms. In a recent study, millions of “virtual reactions” between random chemical combinations were run, and a respectable number of them were verified as correct through real-world duplications of those experiments. https://blogs.sciencemag.org/pipeline/archives/2019/02/11/virtual-screening-as-big-as-it-currently-gets
A new study strengthens a belief I’ve had for a while: The utility that people gain from leisure time is subject to the law of diminishing returns, and actually becomes negative past a certain amount. This casts doubt on the notion that a post-scarcity future world where machines did all the work and humans had endless free time would be utopian. https://www.theatlantic.com/family/archive/2019/02/free-time-life-satisfaction/583171/
An advanced image-editing program has been invented that converts simple doodles to realistic alterations of human faces. https://arxiv.org/pdf/1902.06838.pdf
A Tweet worth considering. I call this the “Technological Unemployment Tipping Point,” and I also think that rather than trying to guess which career field you should aim for, it will someday make sense to just ask the machines which jobs align the best with your skills and interests, and will not become obsolete soon. (You might not like the answer.)

There’s evidence that primitive human societies become less violent by killing off violent males and/or refusing to let them breed. Impulsive behavior–which can lead to violence–has a heritable, genetic component, and measurable changes to a human genepool can happen after just three generations of consistent natural selection. https://www.theatlantic.com/magazine/archive/2019/03/how-humans-tamed-themselves/580447/

Yemeni rebels flew small UAV into a group of government soldiers and detonated it, killing six. It’s useful to think of these sorts of weapons as small guided missiles, which illuminates the fact that their use is just part of the decades-long trend for the technology to get smaller and cheaper. Small groups of people can now afford them. https://www.bbc.com/news/world-middle-east-46822429
The nearly-forgotten Russo-Japanese War of 1904-05 was the first instance when two, modern armies equipped with machine guns clashed, and old infantry tactics were shown to be terribly vulnerable to the weapons. Unfortunately, few generals heeded the war’s lessons, and the same mistakes were made ten years later in WWI. http://weaponsman.com/?p=23151
After the U.S. started building a Space Shuttle, Soviet scientists and economists correctly determined that NASA’s claims the Shuttle would launch cargo into orbit cheaper than rockets were false, and in fact, it would cost more. This led the Soviets to conclude that the Shuttle in fact had a clandestine military purpose, and they found it could serve as a very high-speed nuclear bomber and that it could snatch Soviet spy satellites in orbit. The Soviets didn’t consider that Shuttle in fact had no military function, but that the U.S. government would waste billions of dollars chasing an unattainable goal (but we did). https://youzicha.tumblr.com/post/181657051514/my-favorite-part-about-the-economically-dubious

If it’s January, it means it’s time for me to update my big list of future predictions! I used the 2018 version of this document as a template, and made edits to it as needed. For the sake of transparency, I’ve indicated recently added content by bolding it, and have indicated deleted or moved content with strikethrough.
Like any futurist worth his salt, I’m going to put my credibility on the line by publishing a list of my future predictions. I won’t modify or delete this particular blog entry once it is published, and if my thinking about anything on the list changes, I’ll instead create a new, revised blog entry. Furthermore, as the deadlines for my predictions pass, I’ll reexamine them.
I’ve broken down my predictions by the decade. Any prediction listed under a specific decade will happen by the end of that decade, unless I specify some other date (e.g. – “X will happen early in this decade.”).
2020s
Better, cheaper solar panels and batteries (for grid power storage and cars) will make clean energy as cheap and as reliable as fossil fuel power for entire regions of the world, including some temperate zones. As cost “tipping points” are reached, it will make financial sense for tens of millions of private homeowners and electricity utility companies to install solar panels on their rooftops and on ground installations, respectively. This will be the case even after government clean energy subsidies are inevitably retracted. However, a 100% transition to clean energy won’t finish in rich countries until the middle of the century, and poor countries will use dirty energy well into the second half of the century.
Fracking and the exploitation of tar sands in the U.S. and Canada will together ensure growth in global oil production until around 2030, at which time the installed base of clean energy and batteries will be big enough to take up the slack. There will be no global energy crisis.
Foldable smartphones will enter mass production, though it’s uncertain how much the market will embrace them. These phones will have one, rigid screen on their “front cover,” and one, flexible screen that is twice as big spanning their inner space.
Improvements to smartphone cameras, mirrorless cameras, and perhaps light-field cameras will make D-SLRs obsolete.
Vastly improved VR goggles with better graphics and no need to be plugged into desktop PCs will hit the market. They won’t display perfectly lifelike footage, but they will be much better than what we have today, and portable. Augmented reality (AR) glasses that are much cheaper and better than the original Google Glass will also make their market debuts.
“Full-immersion” audiovisual VR will be commercially available by the end of the decade. They will be capable of displaying video that is visually indistinguishable from real reality: They will have display resolutions, refresh rates, head tracking sensitivities, and wide fields of view that together deliver a visual experience that matches or exceeds the limits of human vision. The goggles won’t be truly “portable” devices because their high processing and energy requirements will probably make them bulky, give them only a few hours of battery life, or even require them to be plugged into another computer. Moreover, the tactile, olfactory, and physical movement/interaction aspects of the experience will remain underdeveloped.
LED light bulbs will become as cheap as CFL and even incandescent bulbs. It won’t make economic sense NOT to buy LEDs, and they will establish market dominance.
“Smart home”/”Wired home” technology will become mature and widespread in developed countries.
Video gaming will dispense with physical media, and games will be completely streamed from the internet or digitally downloaded. Business that exist just to sell game discs (Gamestop) will shut down.
Instead of a typical home entertainment system having a whole bunch of media discs, different media players and cable boxes, there will be one small, multipurpose box that, among other things, boosts WiFi to ensure the TV and all nearby devices can get signals at multi-Gb/s speeds.
Self-driving vehicles will start hitting the roads in large numbers in rich countries. The vehicles won’t drive as efficiently as humans (a lot of hesitation and slowing down for little or no reason), but they’ll be as safe as human drivers. Long-haul trucks that ply simple highway routes will be the first category of vehicles to be fully automated. The transition will be heralded by a big company like Wal-Mart buying 5,000 self-driving tractor trailers to move goods between its distribution centers and stores. Last-mile delivery–involving weaving through side streets, cities and neighborhoods, and physically carrying packages to peoples’ doors–won’t be automated until after this decade. Self-driving, privately owned passenger cars will stay few in number and will be owned by technophiles, rich people, and taxi cab companies.
Thanks to improvements in battery energy density and cost, and in fast-charging technology, electric cars become cost-competitive with gas-powered cars this decade without government subsidies, leading to their rapid adoption. Electric cars are mechanically simpler and more reliable than gas-powered ones, which will hurt the car repair industry. Many gas stations will also go bankrupt or convert to fast charging stations. [Moved from the 2030s because I discovered the technologies are improving faster than I thought.]
Quality of life for people living and working in cities and near highways will improve as more drivers switch to quieter, emissionless electric vehicles.
A machine will pass the Turing Test by the end of this decade. The milestone will attract enormous amounts of attention and will lead to several retests, some of which the machine will fail, proving that it lacks the full range of human intelligence. It will lead to debate over the Turing Test’s validity as a measure of true intelligence (Ray Kurzweil actually talked about this phenomenon of “moving the goalposts” whenever we think about how smart computers are), and many AI experts will point out the existence of decades-long skepticism in the Turing Test in their community.
The best AIs circa 2029 won’t be able to understand and upgrade their own source codes. They will still be narrow AIs, albeit an order of magnitude better than the ones we have today.
Machines will become better than humans at the vast majority of computer, card, and board games. The only exceptions will be very obscure games or recently created games that no one has bothered to program an AI to play yet. But even for those games, there will be AIs with general intelligence and learning abilities that will be “good enough” to play as well as average humans by reading the instruction manuals and teaching themselves through simulated self-play.
The cost of getting your genome sequenced and expertly interpreted will drop below $1,000, and enough about the human genome will have been deciphered to make the cost worth the benefit for everyone. By the end of the decade, it will be common for newborns in rich countries to have their genomes sequenced.
Cheap DNA tests that can measure a person’s innate IQ and core personality traits with high accuracy will become widely available. There is the potential for this to cause social problems.
At-home medical testing kits and diagnostic devices like swallowable camera-pills will become vastly better and more common.
China’s GDP will surpass America’s, India’s population will surpass China’s, and China will never claim the glorious title of being both the richest and most populous country.
Space tourism will become routine thanks to privately owned spacecraft.
Marijuana will be effectively decriminalized in the U.S. Either the federal government will overturn its marijuana prohibitions, or some patchwork of state and federal bans will remain but be so weakened and lightly enforced that there will be no real government barriers to obtaining and using marijuana.
By the end of this decade, photos of almost every living person will be available online (mostly on social media). Apps will exist that can scan through trillions of photos to find your doppelgangers.
Drones will be used in an attempted or successful assassination of at least one major world leader (Note: Venezuela’s Nicholas Maduro wasn’t high profile enough).
2030s
VR and AR goggles will become refined technologies and probably merge into a single type of lightweight device. Like smartphones today, anyone who wants the glasses in 2030 will have them. Even poor people in Africa will be able to buy them. A set of the glasses will last a day on a single charge under normal use.
Augmented reality contact lenses will be invented, though they won’t be as good as AR glasses and they might need remotely linked, body-worn hardware to provide them with power and data.
The bulky V.R. goggles of the 2020s will transform into lightweight, portable V.R. glasses thanks to improved technology. The glasses will display lifelike footage.
Wall-sized, thin, 8K or even 16K TVs will become common in homes in rich countries, and the TVs will be able to display 3D picture without the use of glasses. A sort of virtual reality chamber could be created at moderate cost by installing those TVs on all the walls of a room to create a single, wraparound screen.
The video game industry will be bigger than ever and considered high art.
Books and computer tablets will merge into a single type of device that could be thought of as a “digital book.” It will be a book with several hundred pages made of thin, flexible digital displays (perhaps using ultra-energy efficient e-ink) instead of paper. At the tap of a button, the text on all of the pages will instantly change to display whichever book the user wanted to read at that moment. They could also be used as notebooks in which the user could hand write or draw things with a stylus, which would be saved as image or text files. The devices will fuse the tactile appeal of old-fashioned books with the content flexibility of tablet computers.
Loneliness, social isolation, and other problems caused by overuse of technology and the atomized structure of modern life will be, ironically, cured to a large extent by technology. Chatbots that can hold friendly (and even funny and amusing) conversations with humans for extended periods, diagnose and treat mental illnesses as well as human therapists, and customize themselves to meet the needs of humans will become ubiquitous. The AIs will become adept at analyzing human personalities and matching lonely people with friends and lovers, and at recommending daily activities that will satisfy them, hour-by-hour. Machines will come to understand that constant technology use is antithetical to human nature, so in order to promote human wellness, they find ways to impel humans to get out of their houses, interact with other humans, and be in nature.
House robots will start becoming common in rich countries. They will be slower at doing household tasks than humans, but will still save people hours of labor per week. They may or may not be humanoid. For the sake of safety and minimizing annoyance, most robots will do their work when humans aren’t around. As in, you would come home from work every day and find the floors vacuumed, the lawn mowed, and your laundered clothes in your dresser, with nary a robot in sight since it will have gone back into its closet to recharge. You would never hear the commotion of a clothes washing machine, a vacuum cleaner or a lawnmower. All the work would get done when you were away, as if by magic.
Chatbots will steadily improve their “humanness” over the decade. The instances when AIs say or do something nonsensical will get less and less frequent. Dumber people, children, and people with some types of mental illness will be the first ones to start insisting their AIs are intelligent like humans. Later, average people will start claiming the same. By the end of the decade, a personal assistant AI like “Samantha” from the movie Her will be commercially available.
People will start having genuine personal relationships with AIs and robots. For example, people will resist upgrading to new personal assistant AIs because they will have emotional attachments to their old ones. The destruction of a helper robot or AI might be as emotionally traumatic to some people as the death of a human relative.
Thanks to improvements in battery energy density and cost, and in fast-charging technology, electric cars become cost-competitive with gas-powered cars this decade without government subsidies, leading to their rapid adoption. Electric cars are mechanically simpler and more reliable than gas-powered ones, which will hurt the car repair industry. Many gas stations will also go bankrupt or convert to fast charging stations. [Moved to the 2020s because I discovered the technologies are improving faster than I thought.]
Self-driving cars will become cheap enough and practical enough for average income people to buy, and their driving behavior will become as efficient as an average human. Over the course of this decade, there will be rapid adoption of self-driving cars in rich countries. Freed from driving, people will switch to doing things like watching movies/TV and eating. Car interiors will change accordingly. Road fatalities, and the concomitant demands for traffic police, paramedics, E.R. doctors, car mechanics, and lawyers will sharply decrease. The car insurance industry will shrivel, forcing consolidation. (Humans in those occupations will also face increasing levels of direct job competition from machines over the course of the decade.)
The “big box” business model will start taking over the transportation and car repair industry thanks to the rise of electric, self-driving vehicles and autonomous taxis in place of personal car ownership. The multitudes of small, scattered car repair shops will be replaced by large, centralized car repair facilities that themselves resemble factory assembly lines. Self-driving vehicles will drive to them to have their problems diagnosed and fixed, sparing their human owners from having to waste their time sitting in waiting rooms.
Car ownership won’t die out because it will still be a status symbol, and having a car ready in your driveway will always be more convenient than having to wait even just two minutes for an Uber cab to arrive at the curb. People are lazy.
The ad hoc car rental model exemplified by autonomous Uber cabs and private people renting out their autonomous cars when not in use faces a challenge since daily demand for cars peaks during morning rush hour and afternoon rush hour. In other words, everyone needs a car at the same time each day, so the ratio of cars : people can’t deviate much from, say, 1:2. Of course, if more people telecommuted (almost certain in the future thanks to better VR, faster broadband, and tech-savvy Millennials reaching middle age and taking over the workplace), and if flexible schedules became more widespread (also likely, but within certain limits since most offices can’t function efficiently unless they have “all hands on deck” for at least a few hours each day), the ratio could go even lower. However, there’s still a bottom limit to how few cars a country will need to provide adequate daily transportation for its people.
Automation will start having a major impact on the global economy. Machines will compensate for the shrinkage of the working-age human population in the developed world. Countries with “graying” populations like Japan and Germany will experience a new wave of economic growth. Demand for immigrant laborers will decrease across the world because of machines.
There will be a worldwide increase in the structural unemployment rate thanks to better and cheaper narrow AIs and robots. A plausible scenario would be for the U.S. unemployment rate to be 10%–which was last the case at the nadir of the Great Recession–but for every other economic indicator to be strong. The clear message would be that human labor is becoming decoupled from the economy.
Combining all the best AI and robotics technologies, it will be possible to create general-purpose androids that could function better in the real world (e.g. – perform in the workplace, learn new things, interact with humans, navigate public spaces, manage personal affairs) than the bottom 10% of humans (e.g. – elderly people, the disabled, criminals, the mentally ill, people with poor language abilities or low IQs), and in some narrow domains, the androids will be superhuman (e.g. – physical strength, memory, math abilities). Note that businesses will still find it better to employ task-specific, non-human-looking robots instead of general purpose androids.
By the end of this decade, only poor people, lazy people, and conspiracy theorists (like anti-vaxxers) won’t have their genomes sequenced. It will be trivially cheap, and in fact free for many people (some socialized health care systems will fully subsidize it), and enough will be known about the human genome to make it worthwhile to have the information.
Markets will become brutally competitive and efficient thanks to AIs. Companies will sharply grasp consumer demand through real-time surveillance, and consumers will be alerted to bargains by their personal AIs and devices (e.g. – your AR glasses will visually highlight good deals as you walk through the aisles of a store). Your personal assistant AIs and robots will look out for your self-interest by countering the efforts of other AIs to sway your spending habits in ways that benefit companies and not you.
“Digital immortality” will become possible for average people. Personal assistant AIs, robot servants, and other monitoring devices will be able, through observation alone, to create highly accurate personality profiles of individual humans, and to anticipate their behavior with high fidelity. Voices and mannerisms will be digitally reproducible without any hint of error. Digital simulacra of individual humans will be further refined by having them take voluntary personality tests, and by uploading their genomes, brain scans and other body scans. Even if all of the genetic and biological data couldn’t be made sense of at the moment it was uploaded to an individual’s digital profile, there will be value in saving it since it might be decipherable in the future.
Life expectancy will have increased by a few years thanks to pills and therapies that slightly extend human lifespan. Like, you take a $20 pill each day starting at age 20 and you end up dying at age 87 instead of age 84.
Global oil consumption will peak as people continue switching to other power sources.
Earliest possible date for the first manned Mars mission.
Movie subtitles and the very notion of there being “foreign language films” will become obsolete. Computers will be able to perfectly translate any human language into another, to create perfect digital imitations of any human voice, and to automatically apply CGI so that the mouth movements of people in video footage matches the translated words they’re speaking.
Computer will also be able to automatically enhance old films by accurately colorizing them, removing defects like scratches, and sharpening or focusing footage (one technique will involve interpolating high-res still photos of long-dead actors onto the faces of those same actors in low-res moving footage). Computer enhancement will be so good that we’ll be able to watch films from the early 20th century with near-perfect image and audio clarity.
CGI will get so refined than moviegoers with 20/20 vision won’t be able to see the difference between footage of unaltered human actors and footage of 100% CGI actors.
Lifelike CGI and “performance capture” will enable “digital resurrections” of dead actors. Computers will be able to scan through every scrap of footage with, say, John Wayne in it, and to produce a perfect CGI simulacrum of him that even speaks with his natural voice, and it will be seamlessly inserted into future movies. Elderly actors might also license movie studios to create and use digital simulacra of their younger selves in new movies. The results will be very fascinating, but might also worsen Hollywood’s problem with making formulaic content.
2040s
The world and peoples’ outlooks and priorities will be very different than they were in 2019. Cheap renewable energy will have become widespread and totally negated any worries about an “energy crisis” ever happening, except in exotic, hypothetical scenarios about the distant future. There will be little need for immigration thanks to machine labor and cross-border telecommuting. Moreover, there will be a strong sense in most Western countries that they’re already “diverse enough,” and that there are no further cultural benefits to letting in more foreigners since large communities of most foreign ethnic groups will already exist within their borders. There will be more need than ever for strong social safety nets and entitlement programs thanks to technological unemployment. AI will be a central political and social issue. It won’t be the borderline sci-fi, fringe issue it was in 2019.
Automation, mass unemployment, wealth inequalities between the owners of capital and everyone else, and differential access to expensive human augmentation technologies (such as genetic engineering) will produce overwhelming political pressure for some kind of wealth redistribution and social safety net expansion. Countries that have diligently made small, additive reforms as necessary over the preceding decades will be untroubled. However, countries that failed to adapt their political and economic systems will face upheaval.
2045 will pass without the Technological Singularity happening. Ray Kurzweil will either celebrate his 97th birthday in a wheelchair, or as a popsicle frozen at the Alcor Foundation.
Supercomputers that match or surpass upper-level estimates of the human brain’s computational capabilities will cost a few hundred thousand to a few million dollars apiece, meaning tech companies and universities will be able to afford large numbers of them for AI R&D projects, accelerating progress in the field. Hardware will no longer be the limiting factor to building AGI. If it hasn’t been built yet, it will be due to failure to figure out how to arrange the hardware in the right way to support intelligent thought, and/or to a failure to develop the necessary software.
With robots running the economy, it will be common for businesses to operate 24/7: restaurants will never close, online orders made at 3:00 am will be packed in boxes by 3:10 am, and autonomous delivery trucks will only stop to refuel or exchange cargo.
Advanced energy technology, robot servants, 3D printers, telepresence, and other technologies will allow people to live largely “off-grid” if they choose, while still enjoying a level of comfort that 2019 people would envy.
It will be common for cities, towns and states to heavily restrict or ban human-driven vehicles within their boundaries. A sea change in thinking happens as autonomous cars become accepted as “the norm,” and human-driven cars are thought of as unusual and dangerous.
Over 90% of new car sales in developed countries will be for electric vehicles. Just as the invention of the automobile transformed horses into status goods used for leisure, the rise of electric vehicles will transform internal combustion vehicles into a niche market for richer people.
A global “family tree” showing how all humans are related will be built using written genealogical records and genomic data from the billions of people who have had their DNA sequenced. It will become impossible to hide illegitimate children, and it will also become possible for people to find “genetic doppelgangers”–other people they have no familial relationship to, but with whom, by some coincidence, they share a very large number of genes.
Improved knowledge of human genetics and its relevance to personality traits and interests will strengthen AI’s ability to match humans with friends, lovers, and careers.
Realistic robot sex bots that can move and talk will exist.
2050s
This is the earliest possible time that AGI/SAI will be invented. It will not be able to instantly change everything in the world or to initiate a Singularity, but it will rapidly grow in intelligence, wealth, and power. It will probably be preceded by successful computer simulations of the brains of progressively more complex model organisms, such as flatworms, fruit flies, and lab rats.
Humans will be heavily dependent upon their machines for almost everything (e.g. – friendship, planning the day, random questions to be answered, career advice, legal counseling, medical checkups, driving cars), and the dependency will be so ingrained that humans will reflexively assume that “The Machines are always right.” Consciously and unconsciously, people will yield more and more of their decision-making and opinion-forming to machines, and find that they and the world writ large are better off for it.
In the developed world, less than 50% of people between age 22 and 65 will have gainful full-time jobs. However, unprofitable full-time jobs that only persist thanks to government subsidies (such as someone running a small coffee shop and paying the bills with their monthly UBI check) and full-time volunteer “jobs” (such as picking up trash in the neighborhood) are counted, most people in that age cohort will be “doing stuff” on a full-time basis.
The doomsaying about Global Warming will start to quiet down as the world’s transition to clean energy hits full stride and predictions about catastrophes from people like Al Gore fail to pan out by their deadlines. Sadly, people will just switch to worrying about and arguing about some new set of doomsday prophecies about something else.
By almost all measures, standards of living will be better in 2050 than today. People will commonly have all types of wonderful consumer devices and appliances that we can’t even fathom. However, some narrow aspects of daily life are likely to worsen, such as overcrowding and further erosion of the human character. Just as people today have short memories and take too many things for granted, so shall people in the 2050s fail to appreciate how much the standard of living has risen since today, and they will ignore all the steady triumphs humanity has made over its problems, and by default, people will still believe the world is constantly on the verge of collapsing and that things are always getting worse.
Cheap desalination will provide humanity with unlimited amounts of drinking water and end the prospect of “water wars.”
Mass surveillance and ubiquitous technology will have minimized violent crime and property crime in developed countries: It will be almost impossible to commit such crimes without a surveillance camera or some other type of sensor detecting the act, or without some device recording the criminal’s presence in the area at the time of the act. House robots will contribute by effectively standing guard over your property at night while you sleep.
It will be common for people to have health monitoring devices on and inside of their bodies that continuously track things like their heart rate, blood pressure, respiration rate, and gene expression. If a person has a health emergency or appears likely to have one, his or her devices will send out a distress signal alerting EMS and nearby random citizens. If you walked up to such a person while wearing AR glasses, you would see their vital statistics and would receive instructions on how to assist them (i.e. – How to do CPR). Robots will also be able to render medical aid.
Cities and their suburbs across the world will have experienced massive growth since 2019. Telepresence, relatively easy off-grid living, and technological unemployment will not, on balance, have driven more people out of metro areas than have migrated into them. Farming areas full of flat, boring land will have been depopulated, and many farms will be 100% automated. The people who choose to leave the metro areas for the “wilderness” will concentrate in rural areas (including national parks) where the climate is good, the natural scenery is nice, and there are opportunities for outdoor recreation.
Therapeutic cloning and stem cell therapies will become useful and will effectively extend human lifespan. For example, a 70-year-old with a failing heart will be able to have a new one grown in a lab using his own DNA, and then implanted into his chest to replace the failing original organ. The new heart will be equivalent to what he had when at age 18 years, so it will last another 52 years before it too fails. In a sense, this will represent age reversal to one part of his body.
The first healthy clone of an adult human is born.
Many factories, farms, and supply chains will be 100% automated, and it will be common for goods to not be touched by a human being’s hands until they reach their buyers. Robots will deliver Amazon packages to your doorstep and even carry them into your house. Items ordered off the internet will appear inside your house a few hours later, as if by magic.
The last of America’s Cold War-era weapon platforms (e.g. – the B-52 bomber, F-15 fighter, M1 Abrams tank, Nimitz aircraft carrier) will finally be retired from service. There will be instances where four generations of people from the same military family served on the same type of plane or ship.
Cheap guided bullets, which can make midair course changes and be fired out of conventional man-portable rifles, will become common in advanced armies.
The richest person alive achieves a $1 trillion net worth.
2060s
China will effectively close the technological, military, and standard of living gaps with other developed countries. Aside from the unpleasantness of being a more crowded place, life in China won’t be worse overall than life in Japan or the average European country.
House robots and human-sized worker robots will be as strong, agile, and dexterous as most humans, and their batteries will be energy-dense enough to power them for most of the day. A typical American family might have multiple robot servants that physically follow around the humans each day to help with tasks. The family members will also be continuously monitored and “followed” by A.I.s embedded in their portable personal computing devices and possibly in their bodies.
Cheap home delivery of groceries, robot chefs, and a vast trove of free online recipes will enable people in average households to eat restaurant-quality meals at home every day, at low cost. Predictive algorithms that can appropriately choose new meals for humans based on their known taste preferences and other factors will determine the menu, and many people will face a culinary “satisfaction paradox.”
Machines will understand humans individually and at the species level better than humans understand themselves. They will have highly accurate personality models of most humans along with a comprehensive grasp of human sociology, human decision-making, human psychology, human cognitive biases, and human nature, and will pool the information to accurately predict human behavior. A nascent version of a 1:1 computer simulation of the Earth–with the human population modeled in great detail–will be created.
There will be a small, permanent human presence on the Moon.
If a manned Mars mission hasn’t happened yet, then there’s intense pressure to do so by the centennial of the first Moon landing (1969).
The worldwide number of supercentenarians–people who are at least 110 years old–is sharply higher than it was in 2019: Their population size could be 10 times bigger or more.
Advances in a variety of technologies will make it possible to cryonically freeze humans in a manner that doesn’t pulverize their tissue. However, the technology needed to safely thaw them out won’t be invented for decades.
2070s
100 years after the U.S. “declared war” on cancer, there still will not be a “cure” for most types of cancer, but vaccination, early detection, treatment, and management of cancer will be vastly better, and in countries with modern healthcare systems, most cancer diagnoses will not reduce a person’s life expectancy. Consider that, diabetes and AIDS were once considered “death sentences” that would invariably kill people within a few years of diagnosis, until medicines were developed that transformed them into treatable, chronic health conditions.
It will be technologically and financially feasible for commercial aircraft to produce zero net carbon emissions. The aircraft might use conventional engines powered by synthetic fossil fuels, or they might have electric engines and very energy-dense batteries or fuel cells.
2100
Humans probably won’t be the dominant intelligent life forms on Earth.
Latest possible time that AGI/SAI will be invented. By this point, computer hardware will so powerful that we could do 1:1 digital simulations of human brains. If our AI still falls far short of human-like general intelligence and creativity, then it might be that only organic substrates have the necessary properties to support them.
Worst case scenario is that AGI/Strong AI hasn’t been invented yet, but thousands of different types of highly efficient, task-specific Narrow AIs have (often coupled to robot bodies), and they fill almost every labor niche better than human workers ever could (“Death by a Thousand Cuts” job automation scenario). Humans grow up in a world where no one has to work, and the notion of drudge work, suffering through a daily commute, and involuntarily waking up at 6:00 am five days a week is unfathomable. Every human will have machines that constantly monitor them or follow them around, and meet practically all their needs.
The world could in many ways resemble Ray Kurzweil’s predicted Post-Singularity world. However, the improvements and changes will have accrued thanks to decades of AGI/Strong AI steady effort. Everything will not instantly change on DD/MM/2045 as Kurzweil suggests it will.
Hundreds of millions, and possibly billions, of “digitally immortal avatars” of dead humans will exist, and you will be able to interact with them through a variety of means (in FIVR, through devices like earpieces and TV screens, in the real world if the avatar takes over an android body resembling the human it was based on).
A weak sort of immortality will be available thanks to self-cloning, immortal digital avatars, and perhaps mind uploading. You could clone yourself and instruct your digital avatar–which would be a machine programmed with your personality and memories–to raise the clone and ensure it developed to resemble you. Your digital avatar might have an android body or could exist in a disembodied state.
Life expectancy escape velocity and perhaps medical immortality will be achieved. It will come not from magical, all-purpose nanomachines that fix all your body’s cells and DNA, but from a combination of technologies, including therapeutic cloning of human organs, cybernetic replacements for organs and limbs, and stem cell therapies that regenerate ageing tissues and organs inside the patient’s body. The treatments will be affordable in large part thanks to robot doctors and surgeons who work almost for free, and to medical patents expiring.
All other aspects of medicine and healthcare will have radically advanced. There will be vaccines and cures for almost all contagious diseases. We will be masters of human genetic engineering and know exactly how to produce people that today represent the top 1% of the human race (holistically combining IQ, genetic health, physical attractiveness, and likable/prosocial personality traits). However, the value of even a genius-IQ human will be questionable since intelligent machines will be so much smarter.
Augmentative cybernetics (including direct brain-to-computer links) will exist and be in common use.
FIVR exists wherein AI game masters constantly tailor environments, NPCs and events to suit each player’s needs and to keep them entertained. Every human has his own virtual game universe where he’s #1. With no jobs in the real world to occupy them, it’s quite possible that a large fraction of the human race will willingly choose to live in FIVR. (Related to the satisfaction paradox)
The vast majority of unaugmented human beings will no longer be assets that can invent things and do useful work: they will be liabilities that do (almost) everything worse than intelligent machines and augmented humans. Ergo, the size of a nation’s human population will subtract from its economic and military power, and radical shifts in geopolitics are possible. Geographically large but sparsely populated countries like Russia, Australia and Canada might become very strong. [Changed to reflect the fact that some extraordinarily talented, unaugmented humans like Einstein could still compete with the future “average.”]
The transition to green energy sources will be complete, and humans will no longer be net emitters of greenhouse gases. The means will exist to start reducing global temperatures to restore the Earth to its pre-industrial state, but people will resist because they will have gotten used to the warmer climate. People living in Canada and Russia won’t want their countries to get cold again.
Synthetic meat will taste no different from animal meat, and will be at least as cheap to make. The raising and/or killing of animals for food will be be illegal in many countries, and trends will clearly show the practice heading for worldwide ban.
The means to radical alter human bodies, alter memories, and alter brain structures will be available.
Brain implants will make “telepathy” possible between humans, machines and animals.
Flying cars designed to carry humans could be common, but they will be flown by machines, not humans. Ground vehicles will retain many important advantages (fuel efficiency, cargo capacity, safety, noise level, and more) and won’t become obsolete. Instead of flying cars, it’s more likely that there will be millions of small, autonomous helicopters and VTOL aircraft that will cheaply ferry people through dense, national networks of helipads and airstrips. Autonomous land vehicles would take take passengers to and from the landing sites.
The notion of vehicles (e.g. – cars, planes, and boats) polluting the air will be an alien concept.
Advanced nanomachines could exist.
Vastly improved materials and routine use of very advanced computer design simulations will mean that manufactured objects of all types will be optimally engineered in every respect, and might seem to have “magical” properties. For example, a car will be made of hundreds of different types of alloys, plastics, and glass, each optimized for a different part of the vehicle, and car recalls will never happen since the vehicles will undergo vast amounts of simulated testing in every conceivable driving condition in 1:1 virtual simulations of the real world.
Relatively cheap interplanetary travel (probably just to Mars and to space stations and moons that are about as far as Mars) will exist.
Androids that are outwardly indistinguishable from humans will exist, and humans will hold no advantages over them (e.g. – physical dexterity, fine motor control, appropriateness of facial expressions, capacity for creative thought).
Drones, miniaturized smart weapons, and AIs will dominate warfare, from the top level of national strategy down to the simplest act of combat. The world’s strongest military could, with conventional weapons alone, destroy most of the world’s human population in a short period of time.
The construction and daily operation of prisons will have been fully automated, lowering the monetary costs of incarceration. As such, state prosecutors and judges will no longer feel pressure to let accused criminals have plea deals or to give them shorter prison sentences to ease the burdens of prison overcrowding and high overhead costs.
The term “millionaire” will fall out of use in the U.S. and other Western countries since inflation will have rendered $1 million USD only as valuable as $90,000 USD was in 2019 (assuming a constant inflation rate of 3.0%).
2101 – 2200 AD
Humans will definitely stop being the dominant intelligent life forms on Earth.
Many “humans” will be heavily augmented through genetic engineering, other forms of bioengineering, and cybernetics. People who outwardly look like the normal humans of today might actually have extensive internal modifications that give them superhuman abilities. Non-augmented, entirely “natural” humans like people in 2019 will be looked down upon in the same way you might today look at a very low IQ person with sensory impairments.
Physical disabilities and defects of appearance that cause untold anguish to people in 2019 will be easily and cheaply fixable. For example, male-pattern baldness and obesity will be completely ameliorated with minor medical interventions like pills or outpatient surgery. Missing or deformed limbs will be easily replaced, all types of plastic surgery (including sex reassignment) will be vastly better and cheaper than today, and spinal cord damage will be totally repairable. The global “obesity epidemic” will disappear.
The means to halt and reverse human aging will be created. The human population will come to be dominated by people who are eternally young and beautiful.
Humans and machines will be immortal. Intelligent beings will find it terrifying and tragic to contemplate what it was like for humans in the past, who lived their lives knowing they were doomed to deteriorate and die.
Extreme longevity, better reproductive technologies that eliminate the need for a human partner to have children, and robots that do domestic work and provide companionship (including sex) will weaken the institution of marriage more than any time in human history. An indefinite lifetime of monogamy will be impossible for most people to commit to.
Immortality, the automation of work, and widespread material abundance will completely transform lifestyles. With eternity to look forward to, people won’t feel pressured to get as rich as possible as quickly as possible. As stated, marriage will no longer be viewed as a lifetime commitment, and serial monogamy will probably become the norm. Relationships between parents and offspring will change as longevity erases the disparities in generational outlook and maturity that traditionally characterize parent-child interpersonal dynamics (e.g. – 300-year-old dad doesn’t know any better than his 270-year-old son). The “factory model” of public education–defined by conformity, rote memorization, frequent intelligence testing, and curricula structured to serve the needs of the job market–will disappear. The process of education will be custom-tailored to each person in terms of content, pacing, and style of instruction. Students will be much freer to explore subjects that interest them and to pursue those that best match their talents and interests.
Extinct species for which we have DNA samples (ex – from passenger pigeons on display in a museum) will “resurrected” using genetic technology.
The technology for safely thawing humans out of cryostasis and returning them to good health will be created.
It will be possible to upload human minds to computers. The uploads will not share the same consciousness as their human progenitors, and will be thought of as “copies.”
Gold, silver, and many other “precious metals” will be worth far less than today, adjusting for inflation, because better ways of extracting (including from seawater) them will have been developed. Space mining might also massively boost supplies of the metals, depressing prices. Diamonds will be nearly worthless thanks to better techniques for making them artificially.
The first non-token quantities of minerals derived from asteroid mining will be delivered to the Earth’s surface. (Finding an asteroid that contains valuable minerals, altering its orbit to bring it closer to Earth, and then waiting for it to get here will take decades. No one will become a trillionaire from asteroid mining until well into the 22nd century.)
Intelligent life from Earth will colonize the entire Solar System, all dangerous space objects in our System will be found, the means to deflect or destroy them will be created, and intelligent machines will redesign themselves to be immune to the effects of radiation, solar flares, gamma rays, and EMP. As such, natural phenomena (including global warming) will no longer threaten the existence of civilization. Intelligent beings will find it terrifying and tragic to contemplate what it was like for humans in the past, who were confined to Earth and at the mercy of planet-killing disasters.
“End of the World” prophecies will become far less relevant since civilization will have spread beyond Earth and could be indefinitely self-sustaining even if Earth were destroyed. Some conspiracy theorists and religious people would deal with this by moving on to belief in “End of the Solar System” prophecies, but these will be based on extremely tenuous reasoning.
The locus of civilization and power in our Solar System will shift away from Earth. The vast majority of intelligent life forms outside of Earth will be nonhuman.
A self-sustaining, off-world industrial base will be created.
Spy satellites with lenses big enough to read license plates and discern facial features will be in Earth orbit.
Space probes made in our Solar System and traveling at sub-light speeds will reach nearby stars.
All of the useful knowledge and great works of art that our civilization has produced or discovered could fit into an advanced memory storage device the size of a thumb drive. It will be possible to pair this with something like a self-replicating Von Neumann Probe, creating small, long-lived machines that would know how to rebuild something exactly like our civilization from scratch. Among other data, they would have files on how to build intelligent machines and cloning labs, and files containing the genomes of billions of unique humans and non-human organisms. Such machines could be distributed throughout our Solar System as an “insurance policy” against our extinction, or sent to other star systems to seed them with life.
We will find out whether alien life exists on Mars and the other celestial bodies in our Solar System.
We will reach “Kardashev Type 1 Civilization” status or something equivalent to it.
Intelligent machines will get strong enough to destroy the human race, though it’s impossible to assign odds to whether they’ll choose to do so.
If the “Zoo Hypothesis” is right, and if intelligent aliens have decided not to talk to humans until we’ve reached a high level of intellect, ethics, and culture, then the machine-dominated civilization that will exist on Earth this century might be advanced enough to meet their standards. Uncontrollable emotions and impulses, illogical thinking, tribalism, self-destructive behavior, and fear of the unknown will no longer govern individual and group behavior. Aliens could reveal their existence knowing it wouldn’t cause pandemonium.
Technology will be seamlessly fused with humans, other biological organisms, and the environment itself.
A global network of sensors and drones will identify and track every non-microscopic species on the planet. Cryptids like “bigfoot” and the “Loch Ness Monster” will be definitively proven to not exist. The monitoring network will also make it possible to get highly accurate, real-time counts of entire species populations. Mass gathering of DNA samples–either taken directly from organisms or from biological residue they leave behind–will also allow the full genetic diversity of all non-microscopic species to be known.
Robots will clean up all of the garbage created in human history.
Every significant archaeological site will be excavated and every shipwreck found. There will be no work left for people in the antiquities.
Animals will no longer be raised for food. Additionally, the means will exist to cheaply and artificially produce organic products, like wool and wood.
Tying together two subjects I’ve repeatedly touched on, Russia has sold China advanced turbine engine components for its Type 055 destroyers in exchange for China agreeing to fix up Russia’s sole aircraft carrier. Recall that the Type 055 is one of China’s best ships and is only slightly inferior to U.S. ships of the same type, and Russia’s military floating dock accidentally sank in October. https://www.scmp.com/news/china/military/article/2179553/china-makes-turbine-blade-breakthrough-could-give-type-055
Slovakia has decided to replace its Soviet-era MiG-29s with U.S.-built F-16s, which moves NATO that much closer to logistical interoperability and reduces some of their members’ highly embarrassing dependence on Russia for military assistance. https://www.janes.com/article/85204/slovakia-signs-for-f-16v-fighters
When will we have electric planes? Whenever we have at least tripled the energy density of today’s best batteries. Since energy density doubles roughly every 25 years, a tripling should happen in 38 years. At that point, medium-sized electric passenger planes with up to 125 passengers could profitably ply short- and medium-distance routes. https://arstechnica.com/science/2018/12/when-will-electric-airliners-make-sense/
Porsche has made a 450 kW fast-charging station for electric cars. There’s no technical reason why a car’s batteries couldn’t be recharged in under 10 minutes, which would eliminate one of the few advantages of gas-powered cars. https://newatlas.com/porsche-450-kw-fastcharge-prototype/57659/
Electric cars are more expensive than gas-powered cars because the former’s batteries are expensive. However, the costs are rapidly declining, and at the current rate, Bloomberg predicts electric cars should actually get CHEAPER than gas-powered equivalents by 2026. Crucially, this can be done without the discovery of some new type of battery with new chemistry–we’ll find ways to make existing lithium-ion batteries cheaper. https://data.bloomberglp.com/bnef/sites/14/2017/07/BNEF-Lithium-ion-battery-costs-and-market.pdf
Apollo 8 astronaut Bill Anders thinks a Mars mission is a terrible idea, and that NASA has done nothing but make mistakes and grow more bureaucratic over the last 50 years. https://www.bbc.com/news/science-environment-46364179
Once AIs grasp your skills, intelligence, and personality traits, they’ll be able to match you with jobs more optimally than you or a company’s human resources department could. As technological unemployment accelerates, it will be interesting to see what uses machines find for humans (e.g. doctors picking up roadside trash). https://www.nytimes.com/2018/12/06/business/economy/artificial-intelligence-hiring.html
Some ancient Greek myths describe what we would today think of as robots. “If you think about what any reproducing organism that is under natural selection will do,” Martinho-Turswell told me, “it is going to try to maximize the effect it can get from the minimum investment. That is how you win the evolutionary game.” https://gizmodo.com/the-ancient-origins-of-automation-1830880224
Tokyo Disneyland is building a Beauty and the Beast attraction full of robots that look and move exactly like the animated characters. It’s surreal watching footage of these things. https://youtu.be/bJtNxaTwgz0
Kroger has unveiled an autonomous vehicle meant to delivery groceries to people living near one of their stores. Since it isn’t meant to carry humans, the vehicle is very small, light, and lacks safety features. As autonomous vehicles get more common, the diversity of vehicle shapes and sizes will grow, as they will be purpose-built for specific tasks. In a distant future where AIs run the planet and humans aren’t around, I think smaller volumes of physical “stuff” will move around the planet, and vehicles designed to transport human-sized beings will be a very small fraction of the global vehicle fleet. https://techxplore.com/news/2018-12-grocery-delivery-humans-drivers-underway.html
The concept of a “space of possible minds” has recently come to fascinate me. The human mind is only one possible type of mind, and it thinks and perceives things in unique, but not objective ways. Other species, like bats, ants, and chimps, have very different internal states that could be appropriately called “alien.” Maybe in the future, we’ll have an enormous number of minds–human, animal, hybrid, artificial, blended organic/synthetic–all linked to the same Matrix (for lack of a better term), with each mind specialized for a different type of processing. As data entered the Matrix, it would be shunted to the type of mind best suited to process it. Some of the nodes might be human brains floating in jars, genetically tweaked to be enormous in size and hyperspecialized for specific types of thinking. https://www.edge.org/conversation/murray_shanahan-the-space-of-possible-minds
An update to a link I posted some months ago: The NHS has decided to get rid of its ridiculous fax machines. https://www.bbc.com/news/uk-46497526
Scientists successfully grew hair follicles in vitro, surgically implanted them into mice, and the hair grew. A true cure for human baldness will exist by the end of this century. Eventually, we’ll be able to edit it out of the human genepool. Full heads of hair are attractive, completely shaved heads can also be attractive, but heads covered in visibly thinning or receded hair are universally seen as unattractive. https://www.nature.com/articles/s41467-018-07579-y
Twelve people were hospitalized after getting infections from poorly regulated stem cell clinics in the U.S. Stem cell therapies have enormous long-term potential, but at present, the clinical field is dominated by quacks peddling unproven, expensive treatments to desperately ill people. https://www.nytimes.com/2018/12/20/health/stem-cell-shots-bacteria-fda.html
A German company has invented a way to safely identify the sexes of chickens while they’re still in their eggs. The eggs with males in them could be pulverized as early as the ninth day, when the chicks are still embryos with undeveloped nervous systems. Currently, the egg industry disposes of 4-6 billion hatched male chicks per year by drowning them or grinding them up in huge machines. http://www.seleggt.com/supply-chain-of-shell-eggs/
More proof that California’s decision to put out every wildfire–even if no humans or infrastructure are threatened–interferes with nature’s cycle and only increases the amount of dead, dry wood that will serve as fodder for mega-fires. Global warming doesn’t cause every problem. https://apnews.com/f92cc1767c33459c9312d6fa408cdd50
Syrian government forces have reoccupied the northern city of Manbij for the first time in six years. At last, and for better or worse, the country’ civil war is ending. https://www.bbc.com/news/world-middle-east-46701095
Alan Watts postulated that, if you were a Godlike being with billions of years on your hands, you would eventually start doing mental exercises where you simulated what it would be like to live as a random human on Earth, with no knowledge of your divine nature. Eventually, you would simulate the person you are now. https://steemit.com/christianity/@gbolson/alan-watt-s-perfect-description-of-simulation-theory-or-hell
Humans have a natural bias towards pessimism, attach more weight to bad news than to good news, and in surveys usually underestimate how much things have improved in the world, such as the growth of the global middle class. http://www.rationaloptimist.com/blog/the-persistent-appeal-of-pessimism/
