I agree with you: it is a bit of a "chicken and the egg" problem. I see it mostly as a tool that would be used/suggested by teachers, and that it would possibly be integrated in some editors targeted at beginners, such as Mu

I just joined the beta last week. I keep my notes as md files in a private github repo. I just "loaded" the folder in obsidian and it just worked. I imagine that any editor that you can use with your own storage place would work.
