I think the worst case scenario, and the one that I think is the most likely, is that we plateau at broad and shallow AI. Broad enough such that it can be used to replace many workers (it may not do a great job though), but narrow enough such that we don't really see the kinds of productivity increases that would usher in the pseudo-utopia that many AI folks talk about.
