  • The biggest problem IMO is the fact that all our power generation technology comes down to “boil water to turn turbine”. How we generate the heat changes, but not how we turn it into electricity.

    Technically the ones that use steam to spin turbines are:

    • Coal plants
    • Gas plant
    • Thermal Solar Plants
    • Nuclear Fission Plants
    • Nuclear Fusion Plants

    Then you have ones that spin turbines, but using other methods:

    • Hydro dams and tidal power - use water
    • Engines / Generators - use controlled explosions
    • Wind Turbines - use wind

    Then you have the few that truly don’t use spinning turbines:

    • Solar Panels - they use semi-conductors specially designed so that light causes the electrons in the material to start flowing, directly creating usable electricity.

    • Piezo Electrics - similar semiconductors that react to material stress (bending etc) and cause electrons to flow

    • Batteries & Fuel Cells - store power in chemical form, and the reactions cause the electrons to flow directly

    • (Proposed) Direct Energy Converters - experimental devices long proposed for nuclear fusion reactors that can directly produce flowing electrons. There’s been recent research investigating doing this with fission reactors as well.







  • That’s long and kind of interesting, but also super pop-sci-y.

    The opening talks about how music physically reshapes your brain, but what doesn’t?

    A professional athlete’s brain is going to develop differently from a professional chef or professional writer or professional mathematician. Whether you regularly exercise or take drugs or do whatever will all change which regions of your brain get more or less prominence and resource and change it’s wiring. That how the brain works.

    The rest of the points all follow in a similar manner. Some are interesting and can be taken at face value, a lot have glaring obvious questions unanswered that make it sound like someone is boosting a nothing study result.

    Overall, they don’t add up to a particularly interesting or cohesive point, it honestly feels AI generated.


  • If you’re talking the US government, then no, they don’t need political capital from the people, they just need capital capital and they can use that to swing elections and bribe politicians.

    Regardless, some AI companies will inevitably survive. It is legitimately useful in solving a ton of problems that were near impossible before. Literally this xkcd. Now it’s not “I’ll need a research team and five years”, it’s “sure, easy API hit, we’ll just have to manage cost / use”, in the future, it will be “sure, we’ll just add a background task client side”.






  • We do know that the US was targeting the Iranian Revolutionary Guards Corp (IRGC), and the school is in an IRGC compound.

    The most likely explanation seems to be that they intended to target an IRGC building, but instead hit the school. Whether that’s an issue with the missile’s guidance system, the plane’s targeting system, outdated maps, or a flaw in whatever process the military is using to select targets, is unknown.

    It’s of course, possible that the US intentionally bombed a little girls school, but it seems somewhat unlikely. Even the most hawkish war mongerers recognize that randomly slaughtering hundreds of school girls is not going to gain support for your war.
