The way in which I feel like society is significantly more competent than depicted in Don't Look Up is that plenty of billionaires are not, in fact, idiots.
Some are, for sure, like Zuckerberg. Probably more than half. But not all of them. Vitalik Buterin, for example, the inventor of Etherium, and he's just a phenomenal guy. Gates is not an idiot. Musk is... arguably responsible for making things a lot worse, but obviously not a bad guy.
The most comprehensive single book that makes the case for AI risk is Superintelligence by Nick Bostrom, and I'm pretty sure all of the three people I just named read it. Bill Gates' recommendation was printed on the cover. Yet for some reason, he's still doing global poverty stuff instead of the thing that actually matters. Musk read it and wanted to do something, and well he fucked it up about as bad as was possible. But it still gives me hope because it feels like things could have been different. Maybe this Everet Branch is doomed, but there should be a bunch of other worlds that are doing better. One where Musk founded CloseAI and Gates poured billions into AI safety instead.
