Managers will be replaced by AI when people are willing to work for them. Does anyone really want that? Who the fuck wants to work for an unaccountable machine who you can’t grab a beer with after work? How much life are you willing to abstract away in the name of “efficiency”? To what end?
The exact same thing applies if you are a manager, do you really want a flock of loyal electric sheep to do your bidding? If you’re in management for control over others, how is that satisfying? If you’re in it to mentor, who comes after you? How?
Why does anyone want this? Our societies are already so mechanized and automated yet somehow we have less time than the average medieval peasant to enjoy our allegedly easier lives. What toil has been eliminated thus far?
