I agree and I think the question is then, how much economically valuable work exists in a closed world? My hunch is less than people think. Finance can't rely on LLMs because its adversarial we can't all be listening to the same oracle and evidence of LLMs being any good at trading are nil. And then lawyers, as per usual, will simply regulate their job security into existence. Of course, AI feels amazing to Silicon Valley / Big Tech, software is the product. And often its software you sell to other people making software. But outside of that? Useful but lots of landmines.
People have to come to grips with the possibility that a technology can be extremely impressive but be a bust in utility. I'm not saying that's what AI is, I'm saying that nobody actually knows.
