What on earth are you talking about? Git currently requires intelligence and hard work to learn properly. Regularfry suggests that we shouldn't need hard work to use a version control system. This statement isn't a proposition on the human condition, and doesn't need any proof.
Actually, I disagree. It took me no more than about half an hour to understand and use git properly. I don't particularly consider it to have been hard work.
As for it not being a proposition on the human condition - I mistook what he was saying, but then after it was clarified I understand what was meant. It was unclear to me what was being said - interestingly enough, that is the entire argument being expressed for the reason why git is "hard work".
