You mean the CEO of the company that just rode the AI hype wave to become one of the top 3 most valuable companies in the world? It's his fiduciary duty to say things like that, whether or not he believes them, the same as every other CEO in the AI space.

People really oversell fiduciary duty. Yet the whole point of top-level corporate roles is to steer a company predicated upon opinion, which means that you have great latitude to act without malfeasance.
