For the soft CEO skills, not so much.
Not that that's a deal-breaker. I have a vision of an AI CEO couched as a "strategic thought partner," which the wet-CEO just puppets to grease the skids of acceptance among the employees.
I'd fully trust an AI CEO's decision making, for a predictable business, at least. But some CEOs get paid a lot (deservedly so) because they can make the right decisions in the thick fog of war. Hard to get an AI to make the right decision on something that wasn't in the training corpus.
Still, business strategy isn't as complex as picking winners in the stock market.
