> 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.
