Would your co-workers not make sh!t up if they weren't using LLMs? Pretty sure they would. And MUCH more frequently than the very rare hallucinations one runs into with decent LLMs these days.

My coworkers can be wrong, sure. But no, they weren't making stuff up pre-LLMs. But now making stuff up is automated and easy, so we've gone from simply mistaken to piles of "what the hell is this even trying to say?"
