Ok, so music education specifically... Sadly I can see that.
How to just play instruments and general basic features of genres.. I could see generative AI able to do things on that front. Most notably ability to analyze your performance and identify gaps. Basic rote stuff without need for creativity or soul. The same stuff that countless musicians have already done. I don't think there is a need to genAI up pre-recorded, non interactive lessons, but I could buy interactive AI experience as being feasible and competitive.
At least in theory, though I see that video of someone asking for feedback on their music and it's just literal random farting and the AI was still quite complimentary. But Iif someone told me someone curated a more specialized GenAI experienced that worked better in the context... I would at least believe in the feasibility.
