People don't want to learn git because it's a bad tool. There are better source control systems, that are far easier to reason about, but they don't have the proliferation that git does.
There's a reason git came into existence for linux kernel development. The linux kernel is a project so massive and so decentralized that it needed a fitting tool to be able to tame the chaos. And git did that perfectly.
Out of curiosity though, what to you is a better source control system?
