Some people I know also seem to believe this? Like all the AI providers are going to go bankrupt and we'll just go back to what there was before? Do they not realize that indeed the productivity gains are there?
Sure, there's a lot to be debated about how this fell on many people's laps, on how they are being asked to do more, with the same pay and sometimes putting in more hours. These are pressing issues that have emerged as a natural (or, well, maybe forced for some) consequence of a complete shakeup in the world in general. But I don't think society (i.e. most people) will go back to what was before unless we actually have some form of devastation that really physically prevents us from doing so.
If OpenAI and Anthropic and what have you go bankrupt, others will continue. Maybe the economics will look a bit different, but to think we will just go back to what it was seems, to me, completely nonsensical. But maybe I'm the one spouting nonsense. We'll see in a few years...
