I've watched movies and TV shows. I've read science fiction. And I've read some fantasy. And I'll begrudging admit that I once read an Ayn Rand novel. But, for the life of me, I have no freaking idea where these tech bro billionaires are getting their ideas. Nobody needing jobs? Millions of people working high-paying jobs in space? No need for doctors? Or teachers?

Is it drugs? Licking too much lead paint? Stanford? It's drugs isn't it?

Maybe it's related to men also purportedly thinking about the fall of Rome every 67 seconds or some other such nonsense.
@dabeaz my theory is that having enormous wealth establishes the fallacy that what they think must be correct (otherwise how could they get the wealth) and therefore the world should be the way they believe it should be, because that must be correct, no matter how weird the ideas are. Something along those lines.
