The story only matters if it produces an industry-wide displacement in jobs. Failed billion-dollar IT projects are not a new thing, and don't disrupt the entire labor market.
To be clear: I'm not claiming that AI rollouts won't be billion-dollar failed IT projects! They very well could be. But if that's the case, they aren't going to disrupt the labor market.
Again: you have to pick a lane with the pessimism. Both lanes are valid. I buy neither of them. But recognize a coherent argument when I see one. This, however, isn't one.
