I absolutely don't learn content from AI. LLMs still are at the point where they sound plausible to non-experts, but are just wrong about things you know well. So if you feel you are learning successfully with an LLM teacher, guess which side of that line you are on?

That being said, they absolutely can spin out a topic list and help you find gaps in your knowledge in order to create a self-study plan. As a over-engineered librarian, they are terrific.
