When you're writing into a text file and then save it, you don't have to manually select what lines or pages you're saving - you're saving all of it So? When you're saving a file, you're also overwriting its entire contents. Good luck reverting back to the file before you saved it. There is no automatic model for "this change is worth tracking" and "this change is not important enough to annotate". That's the model that git is enabling, and it has nothing to do with the "save" button in an editor. If anything, it has more to do with the "track changes" feature in Word, but more powerful because it allows you to group multiple edits in the same change.
