This phrase immediately turned the rest of my hair gray. I'm old enough to still think of Git as the "new" version control system, having survived CVS and Subversion before it.
At my mid 90s Unix shop, everyone had to use someone’s script which in turn called sccs. I don’t recall what it did, but I remember being annoyed that someone’s attempt to save keystrokes meant I had to debug alpha-quality script code before the sccs man page was relevant.
Adding -x to the shebang line was the only way to figure out what was really going on.
I still remember dragging my team kicking and screaming away from Subversion. Which, to be fair, was fine. I think GitHub’s rise was really what won it for git vs subversion. The others though, good riddance.
