  • Nobody used blockchain besides scam artists and money laundering schemes. VR was a super niche toy and was not shoved into anything. 3D was... Okay you have a point with that one, but AI can actually be pretty useful where it's actually useful.

    Most people now use chat gpt to some extent voluntarily, without it being shoehorned into an otherwise unrelated product. My mom told me how she was using it to help her rewrite her resume just the other day. I agree that there's a fad of it being forced into everything that doesn't need it, but i think it's here to stay.

    Also, agree to disagree on it having an "incredibly higher possibility of misuse". It's just a tool to let people do things they want to do, whether their intentions are good or not.

  • Glad there's a pair of wireless earbuds with replaceable batteries now, but it's pretty obvious that they only removed the headphone jack on their phone so they could sell more of these. i don't like encouraging scummy business practices like this especially when all it does is worsen my experience and create more waste.

  • This is not it (edit: "this" referring to atmospheric scattering), because if you look at the range of what is in shadow, it is significantly larger than the portion of the sky that you can see. If you could see that far, people in more of a 50% zone would be able to see the sky darken significantly in one direction and be bright in another. What we saw instead was the entire sky darkening evenly.

    The real answer lies mostly in our nonlonear perception of light, meaning that we're much more sensitive to the absolute change in amount of light when there's less light than when there's a lot. So the difference between 100% bright and 50% bright is a lot smaller to us than 50% bright and 0% bright.

    try turning on a flashlight during the day and during the night and you can see the difference the same absolute change in brightness makes in different lighting scenarios. Let's say that some flashlight is 5% the brightness of the sun. Going from 100% to 105% feels like nothing, but going from 0% to 5% is massive.

    In fact you can model this difference using existing perceptually accurate color spaces. Let's take the CIE Lab color space. To find the perceived brightness (L*) you take Y, which is the absolute brightness in the CIE XYZ color space and run it through the following function: 116 f(Y/Yn) - 16 where Yn is the brightness of some predefined white point, and f is effectively the cube root (though it's linear when lower than 6/29).

    If you look at the perceived brightness at 20% absolute brightness, you see that it's not too far from the 75% brightness OP was describing.

    I imagine there are other factors at play, but this is probably the biggest one.

  • You forget that technological progression is typically exponential as developed technologies each help to advance each other, and our collective base of theory grows. I also feel like machine learning can tip that curve a bit like it's currently doing in things like protein research.
