I can indulge the hypothetical and I appreciate your openness to engage in both sides.

I think as you stated, human nature and history is where I am looking at this from. People have a tendency to be unable to sit and do nothing for extended periods of time. I believe we are purpose driven but purpose is pretty loosely defined here.

Indulging the hypothetical (and arguably realistic in some circumstances) that AI replaces a tier of repeatable tasks I believe it would work from the bottom up. Tasks that are extremely repeatable would probably be gone 1:1 and it would be a sliding ratio as complexity increased where having human intervention as a backup becomes justifiable.

This would create a squeeze on the labor force which would bring up the very real and fair question of "How is it that I am unable to survive daily life when 100 - 200 years ago none of this automation / technology existed."

I think this could drive a sort of re-examining of what exists RE: a very inefficient and flawed system with a large amount of people possessing a lot of anxiety and time on their hands. It would be like the Eye of Sauron made up of those who were caught in the crossfire.

On the other side of the haves and have-nots I can imagine there being a very Harrison Bergeron style mindset of trying to popularize pacification until the next great innovation just solves itself.

On the extreme end, I just cannot imagine euthanasia, genocide, or population control schemes. It feels like we have come so far. How could it be possible we regress that far? I could imagine myself not wanting to live through any part of that. This seems like a very extreme and existential point to reach. I am trying to keep my thoughts pinned closer to biological and historical drivers.

I think we are hormone driven chemistry sets. I believe we respond to stimuli. I find it hard to believe anyone at any level could shut off that drive at such a massive scale and accurately predict the other side.
