git is not "the fundamentals". It's a tool that's very difficult to learn but we are forced to use because "it won" at some point.

Git's difficulty is NOT intrinsic; it could be a much better tool if Torvalds were better at UX. In short, I don't blame people who don't want to "learn git". They shouldn't have to learn it anymore than one learns to use a browser or Google docs.

Git isn't fundamental, but version control is. If you're doing development without it, you're making a mistake.

You're likely using a VCS, which is likely git (or jj, hg, fossil, tfs, etc).

Therefore, you should know how to use whatever you're using. It shouldn't be "invisible" to you.
