I care about the internals of git about as much as I care about the internals of my filesystem.

It's probably helpful to know some basics, but do I need to know intimate details of my filesystem to use cp, mv, shell redirection? No. For most basic actions it Just Works™.

The problems in git are purely user-interface based. Other distributed systems have proven you can make a dcvs with a reasonably friendly UI.

That's because a file system is something you already understand, even if you've never actually used an old fashioned paper filing system. The software is providing you with something you understand.

Git is not providing you with something you understand. It is providing you with a DAG and you neither understand what that is or why you need it. The DAG is not the "internals of git". This is the big mistake. It is git. Everything about git is about building that DAG.
