That's such a big question! With regards to enhancing learning, I've already been able to apply it to books (and drafts of books) I'm curious about, but not sure if I have bandwidth to read - between the general "deep dive", the directed (with a prompt) "deep dive", and being able to get chapter summaries and cross references, I've found it immensely helpful in guiding me through works and determining whether or not something is worth my time.
I cannot even begin to put a price on how much that's worth to me!
