> - AI responses I get are walls of written diarrhea

Evidently the people you are communicating with are not good writers/thinkers. That's the prerequisite for effectively using AI for writing help. Just as its the prerequisite for using it to produce code. If you can't code, you can't get Ai to produce good code.

So the real issue here, perhaps, is "vibe writing" rather than "Ai assisted writing".

> I'd rather get the bad/misleading/not-useful response from the person, rather that the good one they made via AI. This way I know they don't know what they're doing, are bad communicators, depend purely on the AI, and thus their position can be eliminated or replaced by someone cheaper merely relaying to/from the AI.

Agreed. But if people who don't understand the issue are feigning competence via AI then that's a fundamental problem of not just competence across many domains, but also character. As I said in another comment, the policy should be something to the effect of "you're paid for competence, integrity etc. If you don't have that, we don't need you. Take that into account when you use Ai"
