For all the stupid Bazinga shit techbros talk about, a lot of the whole transhumanist utopia is possible...(eventually) Just not under capitalism. Even the very rich can't make it happen for them because they can't co-ordinate enough resources to achieve social rather than individual results.

Something like a suite of treatments for robust life extention, for instance, requires not just a miracle treatment but a complete overhaul of research, policy, treatment, care and monitoring methodologies. Even if you're rich enough to just buy and fund a full time research hospital devoted to you and you alone, it won't be enough to achieve the goal.

Even a cabal of the rich wont be able to co ordinate it, because at some point it'll get in the way of financial stability and their lanyard wearing handlers will do to them what the Bavarian government did to King Ludwig when his art projects got in the way of his personal finances (he never spent state funds contrary to popular belief, he was just rich enough to fuck the economy.)

And this is before we get to the fact that billionaires have lying grifters hanging from them like flies on shit.

If you want the cool tech shit, for you or your grandkids, communism is the only option.
