  • Adding on to what GreyEyedGhost said, since the year 2000 the price of solar power (per watt) has fallen by more than 50x. Because of this huge drop in price the installed solar capacity has been doubling every 3 years. That means that in the time since 2020 we’ve built more solar capacity than we did in the previous 20 years combined.

    If that’s not good enough then idk. Imagine holding any other technology to that standard. The model T came out almost 100 years ago for an inflation adjusted price of $27,000 and with an MPG of 7.5. ICE cars today are better in a lot of other ways but they are not 50x cheaper and they are not 50x more fuel efficient than that.








  • If the tank were made of a carbon fiber composite it would make it a little less scary. CF’s high strength and brittle failure mode mean that the tank would “open up” on a seam when ruptured, but would stay mostly intact. Additionally CF’s low density would mean that any small pieces of shrapnel that were created would have limited penetrating power and range.

    Still I’m not sure I would want to stand next to it. At 10,000 PSI a small hole (or opened valve) in such a tank would produce a gas stream with enough energy to seriously injure or kill you (leaks in 4000 PSI steam lines can cut your flesh and create gas pockets inside you). The entire tank letting go all at once would surely create a shockwave that would obliterate you.

    In my personal experience I’ve had to go out of my way to find every quality product I’ve ever purchased, from dishwasher detergent to heat pumps, and none of them were the ones with the highest advertising budgets. You’re right that we all have limited time and can’t possibly evaluate every single thing that exists, but hype men don’t help with that. The professional liars and manipulators that work in advertising only add to the noise and make it take longer to arrive at a conclusion. For example the fact that there are the 12 different brands of space heaters that come in different sizes and shapes and at different price points despite all performing the exact same way. It’s like that with literally everything, from bar soap, to maple syrup, to sunscreen.

    I think this way because I am autistic. I honestly cannot imagine feeling the need for hype men. The phrase “you need hype men” sounds to me like “you need your abuser, you cannot live without them”.

    Something like 35% of autistic people attempt suicide because of what the original post describes (and not just in science, but in every aspect of the world). And yeah, I think if I had to work for someone like Steve Jobs or Elon Musk I would as well.

    “Asshole” is the word for a guy who likes to cut people off in traffic. I think there’s probably a more appropriate word for someone who emotionally manipulates you over the course of years so you’re continually a nervous wreck and can be destroyed any time it’s convenient for him. Seriously if you haven’t watched the interview I linked at least look at the first couple of minutes.

    And at the end of the day, who did this behavior actually benefit? Steve helped make Apple a lot of money, sure, but where did most of that money go? It didn’t go to the employees he abused, that’s for sure. But maybe Apple products ended up benefitting society as a whole, and without Steve we wouldn’t have had that? Well you already said that more often than not Apple’s success didn’t have anything to do with technical superiority.

    The fact that people like this (Steve Jobs, Elon Musk, etc) often head successful companies isn’t an example of how beneficial they are, it’s an example of how broken our system is.
