It's not quite pointless. A prepared outline/mind-map gives you a roadmap for learning beforehand; it can function like a good index.

It's better to memorize domain knowledge upon paths that are clearly understood (thus you are memorizing well-worn, acceptable paths), rather than synthesizing your understanding of a topic as you go along. The second is prone to mistakes and mistaken understanding, unless you're a subject matter expert or charting new domains of knowledge.

That is IMO already done by domain experts in the form of textbooks, courses, university classes etc. And with formal, tested relationships between various islands of knowledge. I'm not too sure how much I would trust an LLM to do this

[Tomte]

That’s an advance organizer (again, Joseph Novak). But it needs to be created by an expert, not by an LLM.

Making the index is part of the learning.
