Most people understand this to be ridiculous. But let's get back to the possibilities tech-savvy writers are actually proposing/attracted to.
E.g.:
Git is built for complex use cases, but perhaps it works just as well for simple ones?
Maybe it can be skinned or otherwise humanized for prose authors?
and my personal favourite (not even being sarcastic)
Maybe git could help authors passively capture valuable revision history that often slips through our fingers and is lost?
