Git is much easier to master than the piano. I played piano for years and can only just play two-handed melodies if they aren't well-aligned.

I've read a few blog posts and half a book on git, and I don't remember the last time I had issues with it.

I also don't recall a junior ever having trouble uploading files with git. Unless they're in an interactive rebase, which wouldn't happen your first time trying out git.
