And that's the part that the AI optimists in these discussions skip over. They want to talk about this new and glorious AI-infested future, but not mention the holocaust that will happen to get there. For most people, the holocaust is the only relevant part, because they'll be destroyed in it [1]. The glorious future of abundance without work is one they'll never see [2].
[1] Most likely through grinding poverty and deprivation, which is how capitalism does it. Not gas chambers or anything.
[2] That future, like you said, a smaller group. I think eventually it will roughly consist of the nepo babies of some billionaires and a smallish group of Lumon-employees (the cultists, not the severed) who must worship them to survive.
