    What a great question.

    A few that come to mind. (In no particular order)

    • Socrates and Aristotle - literally changed the way humanity as a whole thinks, their influence echoes thorough time their ideas are talked about 2500 years later.
    • Marcus Aurelius - stoic philosopher and emperor, set the standard for what a great ruler could be, modern politicians have nothing on him.
    • Albert Einstein - literally changed the way we look at the universe, overturned Newton and his theories have stood up to ever more precise tests.
    • Linus Torvolds - the impact of the Linux kernel on computing cannot be overstated, from the smallest single board computers to the biggest most powerful supercomputers, all run Linux. The internet wouldn’t be the same without it.
    • Johannes Guttenburg - inventer of the printing press, the wide dissemination of knowledge that directly stemmed from this invention changed the world.
    • Alexander Fleming - discovered penicillin, finally gave humanity an effective weapon against bacteria, penicillin and it’s derivatives have saved billions of lives.
    • Stanislav Petrov - Ignored the nuclear early warning system, which erroneously reported 6 launches from the US against the USSR. If he had followed protocol the resulting nuclear response would have triggered WWIII, he saved billions of people by not launching.

    To those saying sports personalities, I doubt people will be talking about their achievements in couple of hundred years.

    Edit: added Stanislav Petrov.






  • As a life long atheist, the simple answer is no.

    The longer answer is:

    Humans have a brain that is effectively an extremely good pattern recognition engine, we are wired to find meaning in things, we anthropomorphize everything with no regard for logic or sanity.

    Humans are hard coded to make religion or religion adjacent things.

    To imagine a world without religion, would mean that we are talking entirely different brain structures, basically we wouldn’t humans anymore.

    In saying the above, I think religion has had its time, it has had a good run. It now causes far more problems than it solves. Having a belief system based on an imaginary sky daddy, really doesn’t add much to the modern world.

    Side note: why do people anthropomorphize their food, it is really messed up.




  • 3 hours a day wouldn’t be that useful. You still have to “be” somewhere 5 days a week.

    What is useful; I did this for a few years; 3 x 8hr days. Mon - Wed, normal work hours, and a 4 day weekend. No need for “public holidays” even paid time off becomes less relevant, when you can switch one week to Wed - Fri. Leaving Thur - Tue as a “normal” way to take time off, giving a 6 day weekend possible every second week.


  • High temperature superconductors.

    Specifically anything above commercial / household freezer (-18C); but if we could get to ~105C (above water boiling) it would change literally everything.

    Electric motors become more efficient over a much greater RPM range.
    Superconducting magnets become much easier to construct and run, this gives us a much better chance at fusion.
    Transmission lines themselves are pretty efficient as it is, but all of the associated switchgear at the conversion points all gets really warm, this could be virtually eliminated.
    The conductors on circuit boards, and potentially inside microchips. This reduces heat loading and thus makes all computing devices more efficient.
    The conductors in batteries; enabling these to be smaller and thus increasing battery energy density.
    Finally making super-capacitors actually viable as longer term energy storage.

    There are so many aspects of life that would be impacted by this one breakthrough, that it is probably the most important thing that will happen this century (scientifically speaking). It would be almost as revolutionary as when electricity itself became widespread.


  • Nuclear Fusion and “net zero emissions” doesn’t really make sense.

    What I think you are trying to say is that fusion is nearing the point where net energy is possible (that is getting more energy out then the amount of energy put in to create the reactions in the first place). Fusion is not practically close yet, but there are tantalizing hints that we are close.

    See this from 2022; the national ignition facility produced more energy that was impacted on the target (2MJ in 3MJ out), but this doesn’t take into account the huge inefficiencies in the laser generators to produce that 2MJ laser pulse.

    There are a bunch of fusion experiments that are hitting massive temperatures (120 - 150MK) which is starting to get into the range where practical fusion could occur, the center of the sun is approx 15MK but also has massive gravity to encourage fusion.

    So fusion is still a decade away at least, but we understand the science much more completely now. We know the problems (well a bunch of them) and it is mostly now a very difficult engineering problem rather a problem of understanding the science.
