I'm worried about their disproportionate ability to influence DAOs.
Humans wont be the only actors in the economy. So will A.I.. And A.I. wont have an ex-wife to take half of their money. An A.I. wont lose respect for money through generations.

Imagine we call it "proof-of-work" selling the dream that you'll never have to work again
AI is just a tool used by human. So if human is getting divorce, wife will take half of money earned by ... AI in this case. Unless you are talking about full consciousness AI. If so, then answer my question... why would a super intelligence manipulate your DAO? What are the benefits for a being who can have everything and needs nothing at the same time? We are just a peace of walking meat.
Check IDENA. It might be interesting for you. Its very small project. It has fixed rewards (50k new coins daily). So there is always inflation but the rate of inflation (percentage) is going down over time. Its not POW, its Proof of Person. Sybil resistance achieved via touring test.
