Again: git as some sort of Platonic ideal of an implementation of a DAG I don't care to argue about. But git's default user interface I will argue about until I'm out of breath, then keep arguing about. Nothing in that interface is designed to aid in learning. Nothing in it is designed so that mastering one task provides discoverability or intuitability of how to perform another task. It is a complex mess of inconsistencies, discontinuities and obscurities which point more to a lack of design or even of someone with authority to perform design than to anything else. It can only be "mastered" through rote memorization, and bears no necessary or useful relationship to the underlying data models and structures whatsoever.
