Yeah. I start using git for personal projects in 2015 and didn’t even know about git diff until last year. All I knew was how to git add, git commit, pull and push. If anything tricky happened I just copied my changes, deleted the repo and recloned. I don’t think you need to teach git beyond those few commands to people but even then I’ve been using bash since I was a kid playing with openSuse so I’d imagine there’s a lot of bash experience that made it easier for me to pick up. I can’t imagine someone who’s never typed ls will have an easy time picking it up.
