The AI bubble will "burst" as soon as they figure out how to inflict all the damage onto regular working people. The housing bubble bursting is what enabled the ownership class to kick a bunch of working people out of their homes and then buy up all the recently vacated real estate for cheap. Nothing about the damage that the rich did to our economy caused any of them to face any actual consequences.
The promise of AI was that it would replace all the workers, but it's not doing that fast enough and it's beginning to look like it never will. We've been hearing that the AI bubble will "burst any day now" for years at this point, but if it happened right now, the ownership class are the ones who would be left holding the bag, and that can't be allowed to happen. When they find a way to take it out of our hides, we'll see that suddenly the "invisible hand of the free market" will present a scenario such that the floodgates open and the bloodbath is finally allowed to proceed. I imagine that's why they started wrapping up so many pension funds and the like in AI investments.
