The thing is that for a majority of cases, this is all one needs to know about git for their job. Knowing git add, git -m commit “Change text”, git push, git branch, git checkout , is most of what a lone programmer does on their code.
Where it gets complicated real fast is collaboration on the same branch. Merge conflicts, outdated pulls, “clever shortcuts,” hacks done by programmers who “kindof” know git at an advanced level, those who don’t understand “least surprise,” and those who cut and paste fixes from Stackexchange or ChatGPT. Plus who has admin access to “undo your changes” so all that work you did and pushed is erased and there’s no record of it anymore. And egos of programmers who refuse any changes you make for weird esoteric reasons. I had a programmer lead who rejected any and all code with comments “because I like clean code. If it’s not in the git log, it’s not a comment.” And his git comments were frustratingly vague and brief. “Fixed issue with ssl python libs,” or “Minor bugfixes.”
