Exactly the type of usage I would hope to see advocated for in the future. As I wrote, when leveraged with Socratic methods and a sort of "interactive documentation", they can really boost one's understanding. Of course, this is predicated on the individual having enough information to know the right questions to ask.
I also do this. It would be better I think to generate exact references to primary and canonical sources to avoid learning LLMisms, or to feed it these and have it ensure its material is anchored to those good references.
