I think its a fallacy to believe people like Zuckerberg or any other stupidly rich person aren't extremely calculative about this. I am very sure they have surrounded themselves by top tier engineers making very informed decisions while their top tier marketing teams make very calculated decisions on how its expressed to the public. The public generally is NOT in favor of AI outside of tech circles so it makes sense to communicate critique of AI to the public.

Executives are salivating at the prospect of AI being able to execute their plans instead of real humans. It is not even about human payroll cost, you can just tell that many higher up executives just complain about how hard it is to steer the ship and get people to work on the right things.

Unfortunately they also don't realize just how much decision-making real people do lower down the org-chart. Critical decisions are often done by the leaf nodes, often without even discussing it internally with the leaf-node team. AI will likely not be very good at this kind of decision making or realize any decision needs to be made at all.

Are you really saying that Mark Zuckerberg, CEO of "Meta", can't make a massive miscalculation?

At that level it becomes hard not to surround yourself with obsequious yes men who will instinctively agree with all your harebrained ideas about virtual reality or AI.
