I think you're underestimating a bit. We must implement AI because they were able to sell it so good that they got billion $ investors (see all the money coming from Qatar/saudi arabia etc). That's a lot of money coming in that allows to innovate/etc.
I swear that every 5-10 years, corporate CEOs all get together in a secret meeting where they all agree on the next buzzword technology. They invite Harvard Business Review and the tech press to give them their marching orders. Then, finally, the white smoke comes forth from the chimney indicating the next bubble buzzword has been chosen, and the industry goes bananas over it for 10 years for no reason.
It "could be anything", but the current AI trends/updates are really impressive. This is why they are investing.
If we reach a limit in the next 5 years, so be it. But it's driving and pushing for a paradigm shift in the way things work - search, coding, tooling, etc. It touches almost anything people do, not a specific group of people, but society as a whole.
