>I know my text editor very well so that I can write efficiently. I know my compiler well enough to use it to build my programs in the various configurations I need. Aren't these somewhat different details to know tho, compared to knowing the insides of git? Knowing the commands, and options available in an editor is familiarity with an interface. You don't need to know exactly how it stores the buffer so it can stay responsive with large files, you don't need to know the rendering algorithms involved, etc. etc. Just the same, I don't think being able to use a compiler effectively depends on knowing how it does register allocation, or knowing if the parser is LALR or recursive descent. These are all implementation details. Good interfaces generally abstract over them, and present the user with what they need to use it. Version control being necessary doesn't change how people should approach learning it. At least, no more than we should expect good drivers to understand piston engines. (Though, drivers of manual transmission cars should probably understand clutches. Maybe Git is comparable to that?)
