I mean the answer is simple, money. There's a bajillion dollars getting shoved into this crap, and most of the bulls are themselves pushing some AI thing. Look at YC, pretty much everything they're funding has some mention of AI. It's a massive bubble with people trying to cash in on the hype. Plus the managerial class being the scum they are, they're bullish because they keep getting sold on the idea that they can replace swathes of workers.
