LLMs are so good at telling me about things I know little to nothing about, but when when I ask about things I have expert knowledge on they consistently fail, hallucinate, and confidently lie...
But it's still not completely right. LLMs are actually great to tell you about things you know little about. You just have to take names, ideas, and references from it, not facts.
(And that makes agentic coding almost useless, by the way.)
