"just learn git" unpacks to two different things - gaining an understanding of the git model and how the various operations query and modify the repository state, and learning the arcane minutiae of git's command line invocations. the former is indeed a very valuable part of levelling up as a developer; the latter is only useful insofar as you have to interact with the `git` command line tool. it has no intrinsic worth, and if someone would rather write and use `gut` instead, more power to them!
