I'm not super optimistic personally, but isn't the optimistic outcome obvious? If AGI takes over, solves robotics, (and doesn't kill us all,) then we could see the elimination of all human labor for the purposes of meeting necessities.

Unless AI can solve the "people with access to capital would prefer to keep it rather than share it freely" problem, this doesn't actually lead to human flourishing. You need to pay for the labor-bot and you don't have any money to do so because there are no jobs available for you.

Given that AI doesn't seem to be solving the allocation problem even for things like distributing fairly inexpensive TB drugs to people who need them, I'm not holding my breath.

Do you think our economic system is prepared to cope with that?
