And you were born with an understanding of how a keyboard and mouse worked or how windows seperated different GUI contexts and what all those symbols around them meant? I'm not saying you have to understand the nuts and bolts because abstractions exist but those abstractions still present you with a model and you need to understand that model to use them. People often present git's model mixed in with its nuts and bolts, which I think is unhelpful because the model is actually really simple and the nuts and bolts are not so important.
