My hypothesis is people will get burned out on this unguided learning via LLMs and still want some sort of curated/guided learning experience through material to understand some subject.

There is the problem of "I don't know what I don't know" that a course can solve for you. An LLM can sort of do that, but you have to take its word for it, and it does it pretty much strictly worse at the moment (but is much more flexible).

I'm less optimistic. Already 20+ years ago many people complained if you pointed them to books which answered their questions in depth. The standard reply was "just tell me how to solve this particular problem" instead.
