There is sadly ample fiscal headroom in mundane drone-like work that was being outsourced (still cheaply, I might add) that AI can replace and even do a marginally better job of. I suspect AI prices can even increase and it will still be profitable for enterprises.
Companies like this will certainly keep expanding their AI use, and once they commit to that, there's little stopping them from moving to open models or local inference if need be.
My concern is less over the bubble and more over the social cost of AI. Call centres and the like provide a tremendous number of jobs. As AI moves into enterprises more and more, where are all these people supposed to work? Become baristas? They certainly won't be "learning to code"... What sorts of social and other unrests will this cause?
These forces I think will muddy the waters and make predictions difficult. Say what you want about the AI bubble, but if it pops, it will be different than previous ones. The bubble doesn't even need to burst because of the insane economic model, if enough people are economically devastated by it, it will cause ripple effects of its own.
