Alternative interpretation: git is a terrible terrible tool. It solve's Linus' problem, but he also wrote the damn thing. Had GitHub not entered the scene we'd likely all be using something else, maybe even SVN still.

Maybe distributed source control really is this complicated and treating git as a deep skill is justified, but having also used Darcs and Mercurial I have a hard time believing that git's usability issues are inherent complexity and are in fact an artifact of git itself.
