Git is certainly the only version control system I've ever used: I started using it when I was a new grad 15 years ago. Everything I know about Subversion or CVS (almost nothing) I know from reading explanations of Git aimed at their users or from trying to understand the origin of some of Git's terminology choices :) re whether the snapshot based world view is "natural" or not to Git users: I did some very unscientific polls about people's mental models of Git a while back at https://jvns.ca/blog/2024/03/28/git-poll-results/#commits That one says that 42% of folks who responded think of commits as "snapshots" and 50% as "diffs", which feels encouraging to me: after all, the poll doesn't ask how Git represents commits internally, and many people replied in the comments to say that they think of commits in both ways depending on the situation.
