It's mostly bad actors, and a smattering of optimists who believe that despite its current problems, AI will eventually and inevitably get better. I also wish the whole thing would calm down and come back to reality, but I don't think it's a bubble that will pop. It will continue to get artificially puffed up for a while because too many businesses and people have invested too much for them to just quit (sunk cost falacy) and there's a big enough market in a certain class of writer/developer/etc... for which the short term benefits will justify the continued existence of the AI products for a while. My prediction is that as the long term benefits for honest users peter out, the bubble won't pop, but deflate into a wrinkled 10 day old helium balloon. There will still be a big enough market driven by cons, ad tech and people trying to suck up as many ad dollars as possible, and other bad actors, that the tech will persist, and continue to infest the web/world for quite a while.

AI is the new crypto. Lots of promise and big ideas, lots of people with blind faith about what it will one day become, a lot of people gaming the system for quick gains at the expense of others. But it never actually becomes what it pretends/promises to be and is filled with people continuing the grift trying to make a buck off the next guy. AI just has better marketing and more corporate buy in than crypto. But neither are going anywhere.
