Bloom's 2 sigma problem
I am already working on fixing this: https://github.com/trane-project/trane/No AI needed. Just an old fashioned depth first search through a graph of skills and dependencies.I made it to help me practice music, but I have been branching out and using it to study math for a few weeks. I find myself saying "just one question more" and then spending another half hour in it.Still needs more material to be useful to other people but it's a solid experience. I learned and memorized how to play most of the notes in the saxophone with good intonation in about a week, as a complete beginner.
