if robots are the foundation of society, then we should all benefit equally[/i] from them.
Says who? We didn't all benefit equally from the domestication of cows. Some people are lactose intolerant. I really don't understand this obsession with equality that is unheard of in nature. It's completely subjective. Equality in outcomes or equality in opportunity? Equal rewards for effort or for productivity? The former produce what economists call "perverse incentives".

EDIT: I see now that this is one of the subjects in your link.
