Even if a human expert responds about something in their domain of expertise, you have to think critically about the answer. Something that fails 1% of the time is often more dangerous than something that fails 10% of the time. The best way to use an LLM for learning is to ask a question, assume it's getting things wrong, and use that to probe your knowledge which you can iteratively use to prove the LLM's knowledge. Human experts don't put up with that and are a much more limited resource.
