> can actually be pretty useful. It indicates somebody already minimally investigated a thing

Every time this happens to me at work one of two things happens:

1) I know a bit about the topic, and they're proudly regurgitating an LLM about an aspect of the topic we didn't discuss last time. They think they're telling me something I don't know, while in reality they're exposing how haphazard their LLM use was.

2) I don't know about the topic, so I have to judge the usefulness of what they say based on all the times that person did scenario Number 1.

Yeah if the person doing it is smart I would trust they had the reasonable prompt and ruled out flagrant BS answers. Sometimes the key thing is just to know the name of the thing for the answer. It's equally as good/annoying as reporting what Google search gives for the answer. I guess I assume mostly people will do the AI query/search and then decide to share the answer based on how good or useful it seems.
