You're cherry picking a handful of nerd billionaires who are getting into, lets face it, a pretty big gamble right now. SpaceX is the only success story of all the commercial space companies and the whole "The rich will find a way to become immortal and sell us the serum" scenario is this weird opposite of classism.
I'd also add that this mentality is why we had kings and dicators in human history. We're just too prone to thinking a few alpha males will Fix Everything and pesky things like division of power, politics, just get in the way of our Ayn Rand heroes. I think you can figure out in the lifecycle of kingdoms and dictatorships that the endgame is never paradise. Its usually a long ongoing nightmare of cronyism and human rights violations.
Weird to see a western person dismiss the incredible priviledge he has and free speech rights and lack of obligations of serfdom/slavery suddenly take up the mantle of 'let the alpha males fix everything you stupid bureaucratic peons.'
Just out of curiosity, do you think these gentle nerds would have thrived in a environment like the one you're applauding? Imagine Bill Joy or Wozniack or Bezos born into a crony capitalistic environment. Something tells me without the nannying of the western enlightened nanny state with its safe streets and cheap public education, would any of these guys have had the class mobility or opportunity to move upwards? Makes me wonder how many geniuses are being pissed away in places where the alpha males rule harshly. The world has probably lost hundreds of north korean and somalian genuises.
