It makes sense to me that AI could conceivably already be as good at making the hard, data-based decisions that CEOs make, and that, therefore, they could one day be replaced by AI. Meanwhile, you've got the soft skills part of being an executive, which humans are better at (as long as the people they deal with are also humans). So, you could split that CEO role into two parts, each specializing in half of what a CEO today does. Both roles would probably do a better job than the median CEO today, and get paid less overall.
But that "not anytime soon" part is the only thing I disagree with. Because I just don't know how long the timeline is for stuff like that. It can change pretty fast.
