I disagree that Bob doesn't produce actual results, or that something that is mostly rubbish, but partly "interesting" is an actual result. We know the current incentives are all sorts of broken, across the board. Goodhart's law and all that. To me the question isn't who remains in academia given the current broken model, but who would remain in academia in one that isn't as broken.

To put a point on it, if public distrust of science becomes big enough, it all can go away before you can say "cultural revolution" or "fascist strongman". Then there'd be no more academia, and its shell would be inhabited by party members, so to speak. I'd gladly sacrifice the ability of Alice and others like her to live off producing "mostly rubbish" to at least have a chance to save science itself.
