This has been the same argument since the invention of pen and paper. Yes, the tools reduce engagement and immediate recall and memory, but also free up energy to focus on more and larger problems.

Seems to focus only on the first part and not on the other end of it.

Without the engagement on the material you are studying you will not have the context to know and therefore focus on the larger problem. Deep immersion in the material allows you to make the connections. With AI spoon feeding you will not have that immersion.
