    Artificial stem cells seem like the next thing to really revolutionize medicine.

    Quantum computers for brute force hacks seems doable in 100.

    Eye tracking pointer devices will likely be more convenient than mice within a dozen or two years. This will probably be widely available for people who are paralyzed first.

    Diamond processors are always 10 years away, but I think we can do it in 100. This would revolutionize the amount of power we can put through a chip without worrying about cooling.

    Quick charge capacitor replacements for standard rechargble batteries

    Low yield fusion plants. I’d like to think of them as capable of high yield, but it’s much harder than initially thought. Some ideas are quite promising for low yield.

    I’d really like to at least see humanity fully switch to clean energy in my lifetime but I’m losing hope.

    I should already be able to take a self-driving flying taxi to work. I should already be able to vacation on the moon. We shouldn’t be burning stuff to power all our modern tech.

    I grew up on 80s/90s scifi. I hope humanity can get it’s shit together and that the current anti-intellectualism phase we’re in is just part of a larger cycle.

          To be fair, you have a 1 in 95 chance of dying in an automobile accident.

          Based on modern safety standards for everything else, that’s unacceptable.

          If I offered you a job and said you have a 1 in 95 chance of dying from working this job, you would refuse. The most dangerous job in the USA is logging, with about a 1 in 1000 chance of dying. More lumberjacks die driving home than die working their extremely dangerous job.

          Not only should we have self-driving flying taxis by now, but we should also at least have level 5 self-driving cars so people aren’t constantly dying driving to get groceries or pick up their kids.

            No

            What we need is more bicycle roads, pedestrian walk ways and public transportation

            Suffice to say that 1 bus is safer than 30 cars but it also generates a shit tonne less pollution, but also keep in mind that the vast majority of car rides are short distance, even in the US

            In the Netherlands they changed everything to prefer bicycles and walking and it’s noticable. It changed architecture. It’s why in the Netherlands there are broad loads of small super markets. Wherever you are within a town you’ll have a super market at walking distance

            Many people there don’t have a car, not because they can’t afford it but because they don’t want one. Cars are expensive, cumbersome, dangerous, and ugly. You won’t see depressing towns there that are 70% concrete roads or parking lots. It’s all beautiful because they got rid of all that, it isn’t needed.

            In before anyone starts about how this can’t be done in the US: it can, and quite easily. Pedestrian and bicycle infrastructure costs a fraction of car infrastructure, it’s easier and faster to build, no parking lots required, you can now make that a store and get taxes from it, it’ll make your cities richer. People get more exercise, they’ll be healthier and happier, there are no downsides. Inclines near mountainous areas? Electrical bikes to the rescue.

            Please please do NOT push this car stuff, especially flying car stuff. It’s not needed, it’s a waste, it’s polluting even when electric, and we have flying cars, they’re called planes and there is a reason why pilots need to learn and train a LOT more than car drivers.

              Sure. I agree with all of that. But I live in a suburban sprawl of a US city that is just dense enough to have lots of cars, but nowhere near dense enough to have decent public transportation…unless we as a society decided to bulldoze this entire vast suburban landscape and start over with density as a goal. It’s hot here too. Nobody is riding their bike 12 miles to work in 95⁰ weather (35⁰ for our metric homies).

              Maybe within the next few years the Netherlands will let me and my family in as refugees so I can bike everywhere on a 72⁰ summer day.

              But I like where your head’s at. Hopefully you’re young and can make a difference.

          Exceeding FTL (and breaking causality) is basically a sci fi trope at this point with about as much credibility as psychics. To have at least some credibility you need one of: a testable hypothesis, or an unexplained phenomenon. Right now we have neither. At best, we have some equations, that work below light speed, where we can extrapolate past light speed and see how the math works. The problem is: none of these equations are testable as they all contain infinities or other asymptotic features that prevent passing light speed itself. So, if there’s no viable math to get from sublight to FTL, and there’s no unexplained phenomena, then what we’re left with is nothing.

          Even quantum entanglement, which is a darling of sci fi whenever they need a plot device (hello Le Guin and the ansible), has categorically been shown to obey causality and the light speed limit in every lab test.

          At some point it’s like asking for negative mass, antigravity, or other things that the math would allow. Except our universe doesn’t.

            in scifi there seems to be several types of ftl: one is typical warp like drive of trek, and star wars, and hyperdrives which is similar to transwarp/slipstream/xindi vortex travel, which is interdimensional travel so not technically violating light speed. and the least common one is interdimensional teleportation, BSG reimanging uses this tech, although they dint bother trying to explain it with technobabble at all, because of the showrunners allergy to trek-speak. STD, and a single episode arc of tng a group of terrorists were using interdimensional transporters.

            trek also had other forms of ftl, but those are very rare, and its pretty much similar to the last 2.

              And every one of those are as grounded in reality as sci fi’s agelong obsession telepaths, telekinesis, or mutants with powers.

              There is a class of modern sci fi authors are all coming to terms with this.

              I’d recommend checking out stories like Neptune’s Brood – sci fi which takes on interstellar economics in slower than light scenarios.

          Basically, physics says that nothing, not even information can actually travel faster than the speed of light. It’s a universal limit that shows up when you do the math on relativity. This concept is called “causality”.

          Because of this, FTL communication is probably impossible. Quantum entanglement seems like it could provide a loophole, but it doesn’t actually work that way. To actually use quantum entanglement for communication, it actually needs a confirmation message, which would have to be delivered by a different means (every quantum message needs a non-quantum confirmation). That confirmation would be bound by the speed of light, thus preserving causality.

          This is a very very rough description based on my memory, so some details may be a little off, but it should cover the gist. This article goes into more detail:

          https://bigthink.com/starts-with-a-bang/quantum-entanglement-faster-than-light/

          Edit: After reading, the answer is more that attempting to impart information onto the entangled particles to send a message necessarily breaks the entanglement and thus does not transmit the information to the other side. Entangling the particles makes their states related to each other, but only at the time of entanglement, and anything that changes either particle (including measuring it) will break the entanglement going forward.

            Yup. You just summed up the start of the conversation I had with ChatGPT to figure out exactly what we were talking about Here and why the fact that even if we can’t directly send coherent information, if it appears that a change in particle A directly causes a change in particle B, and it appears that that causation happened Instantaneously, we can’t ever prove it or measure it or know it for certain, because the proving measuring and knowing would have to have occurred at instantaneously themselves in order to actually be proof at all. The even more fascinating part I wound up with is discovering the Holographic Principle, as discovered by Beckenstein and later expanded on and proven by Stephen Hawking, that says that all information in the 3-D world is actually encoded into a 2-D framework. That one blew my mind and I’m gonna be thinking about that for a while.

              The holographic principle is fascinating, though a quick nitpick: I’m pretty sure we’ve only proven it for contracting spacetimes (as opposed to our expanding one), but a lot of people imagine it does apply to ours as well (I certainly suspect it does)

        The idea is this:

        2 particles are quantum entangled. Whatever happens to one instantly happens to the other regardless of distance.

        So you establish a state that means “0” and a state that means “1” and you can send binary.

        At a minimum, you have quantum Morse code.

          If you change one of the particles it just breaks the entanglement. If you measure one, then you instantly know the state the other will have when measured, but the result of your measurement - and therefore the other one also - is random. The only way to correlate the two measurements of the two particles is to send the results (at C or slower) to the same place and compare them. Otherwise each just looks like a random result.

              I read it. Doesn’t mention FTL, because that’s not a possibility for actually transmitting info.

              Edit: I think the way these quantum encryption systems work is that basically the photons (and I assume it’s polarization being measured) become the encryption key to a message that is sent conventionally.

              Like the sender generates a bunch of entangled photons, sends the paired ones to the recipient, measures their photons and uses the results to encrypt the message, the receiver measures theirs and gets the same results, the sender sends the encrypted message over email or whatever, and the recipient has the same key because of entanglement.
              Meanwhile an eavesdropper measuring the photons would mess them up for the recipient so the message wouldn’t decrypt.

            (I know nothing about this)

            Could you to the sub-C measurement test enough times to show that it just empirically works, and then use it on that basis? Or are you saying that the sub-C measurement would prove that it doesn’t work (and it produces random noise)?

              I’m not sure what you mean by ‘use it on that basis’. Yes, entanglement has been proven to work, but it can’t be used to communicate FTL.

          I’m familiar with quantum entanglement. It doesn’t work because you have no way of affecting which state you’ll measure, and thus what state the other particle will be in.

                That’s not the part you were trying to say couldn’t be done. ;) You were trying to argue that quantum entanglement couldn’t be used to communicate, clearly it can.

                The FTL bit is the science fiction premise of the thread. ;)

                  That is indeed that bit I was saying couldn’t be done. Entanglement alone can’t be used to communicate; a signal has to be sent conventionally over the distance.

                  The FTL bit is physically impossible, so it’s not really “achievable in a reasonable time-frame”
