So far, it appears those smart people have created a ideological caused self-extinction of western civilizations and thus a take-over by unapologetic expansionist imperialist cultural systems. Not very smart and not very longterm loadbearing.. it seems those "smart" people are mostly ideological driven and unable to work with the flawed, half-animal humans given.

Honestly -- I think the deeper point here is Nietzsche's: there's nothing wrong about winning. Nothing wrong about conquest. Nothing wrong with having three kids and outcompeting your neighbor.

This cultural meme spreads because short term gluttony is not, in fact, winning: if you eat your seed-corn, next year you starve. And winning is not about quantity either, but quality: I unapologetically want to shape the light-cone in my image, and my image recoils at torment.
