I think the truth is that at many (most?) places, perceived productivity and convincing is all that matters. You don't actually have to be productive if you can convince the right people above you that you are productive. You don't have to have competence if you can convince them of your competence. You don't have to have a feasible proposal if you can convince them it is feasible. And you don't have to ship a successful product if you can convince them it is successful. It isn't specifically about AI or LLMs. AI makes the convincing easier, but before AI, the usual professional convincers were using other tools to do the convincing. We've all worked with a few of those guys whose primary skill was this kind of convincing, and they often rocket up high on the org chart before perception ever has a chance to be compared with reality.
