I'd assume that many CEO are driven by the same urge to please the board. And depending on your board, there might be people on it who spend many hours per week on LinkedIn, and see all the success stories around AI, maybe experienced something first hand.
Good news: It's, from my estimate, only a phase. Like when blockchain hit, and everyone wanted to be involved. This time - and that worries me - the ressources involved are more expensive, though. There might be a stronger incentive for people to "get their money back". I haven't thought about the implications yet.
