While I agree that AIs would do a good job…
Would you rather take instructions from a ruthless robot or ruthless flesh sack?
A robot with access to all of the company data and mediocre decision making wouldn’t be terrible.
The flesh sack is choosing to be an insufferable twat, and the robot either doesn't have any choice or has a decent statistical justification for what it does.
Weirdly enough, I'd take the robot. At least we can pretend the robot doesn't know any better. The human is actively choosing to be a dick and profiting off it.
