If I needed to know something and asked a person about it, I would be super angry if he didn't know a correct answer but just made up something that sounded like an answer. But that's what AI is when the answer isn't available to it from a real source -- why would anyone in his right mind need that?
I can see it being useful for AI to give me links or references to actual human created sources (humans can have credibility that can be evaluated, but for large language models that wouldn't mean anything). But finding links is what search engines had already been doing since the days of AltaVista.
