You mean placebo? Not sure that Dunning-Kruger is applicable here

I wonder if this means that going to the gym is a huge source of exposure then. Enclosed environment with rubber mat flooring and weights constantly banging against it..

This isn’t Reddit. Awesome bacon sauce posts generally aren’t appreciated

You obviously haven’t done it both ways and are assuming that spearing requires more dexterity than cutting. Hilarious that you could just try it for yourself and figure out that knife in the dominant hand works well but choose instead to bore everyone with your ignorance and stunning closemindedness

I think the reality is that the brain is an organ and loses functionality in old age, similar to the heart, lungs, liver, skin, whatever you want to name. Lifestyle plays a significant role and I think you’ll find that people that take care of themselves and have less loss of functionality are significantly happier and wiser in their old age. I do think that there’s adaptive functionality in hormonal changes though

Pretty sure the people who have to choose between eating and a $2 adapter and not eating and a Bluetooth keyboard have a better understanding of the trade offs and what’s viable than you do. Not sure what real point you’re trying to make here

It doesn’t matter if companies ditch people or not. If AI progress continues at the current rate the world will be completely unrecognisable in 10 years. The consumer and capitalist systems are almost certainly not a part of that world and the people making AI know that

The Youtube video was also made by the Indian Government. Validating the Indian Government's claim against the Indian Government's same claim (Test 15 in this case) probably doesn't tell us much

My ChatGPT said lead chromate isn't soluble in water so it's unreliable :(

Depending on how quickly the body would convert the plastic in this highly unrealistic hypothetical, that might work out just fine

I get that your point is that we don’t have a strong intuition for lenses and that’s tied to a lack of evolutionary reason to have them. I agree and suspect that might be the point of why Apple are using a the lens effects. We don’t need to go so far as to say the natural world is completely devoid of such phenomena. Of course they’re there but they’re largely not relevant to survival throughout human history

Not saying this makes the ui good but it should go without saying that the natural world has water which acts as a lens.

Also, of course we have perception of droplets. What we don’t have is an intuitive understanding of how light interacts with droplets.

I suspect that Apple are trying to leverage this lack of intuition to make their ui interesting to look at in an evergreen way. New backgrounds mean new interesting interactions. I’m not confident that they’ve succeeded or that that’s actually a good goal to have though. I have it on my iPhone 13 and personally I find it annoying to parse, and I feel relief when I go back to traditional apps untouched by the update like Google Maps

How is currying favor and badly attempting to dogwhile (turned out to be a full blown whistle that people somehow still didn't hear) being an edgelord? Being an edgelord is saying something 'wrong' to try to be badass. Elon is funding and supporting far right parties to try to enrich himself. These things are not the same lol

Considering his support of far right German parties around the same time, it seems far more likely he was doing it to curry favour like he’s tried to do with Trump

How is he exaggerating the situation? What is false about the criticism? Are you referring to a previous time where they cried wolf? I read through the Twitter thread and GrapheneOS seemed pretty even keeled and above board about it to me (even if that is uncharacteristic)
