The CEO role is mostly about doing what you are told by shareholders. Last thing you want to do is remove the final limitations of a conscience from the position. An AI for ceo’ing will be optimised to be evil. More evil than the average psychopathic/narcissistic/Machiavellian CEO.
edit: Downvoters might wanna learn to read more thoroughly. I’m saying CEOs have almost no conscience. I’m not saying they have more than a narc/psycho/machi level of conscience, I’m saying they have a tiny tiny scrap of it(rarely), which the AI will not have.
