I used SVN once for my capstone project 11 years ago, graduated that same year, and literally haven't encountered it a single time in my career since then.

It definitely wasn't everywhere 10 years ago (but github was). Do you mean 15-20?

Regardless, having completed a CS degree during the period SVN was supposedly everywhere and only encountered it once because someone in my capstone team knew how to use it, I'm inclined to think it didn't permeate everything the way git does now.

If I could complete a bachelors in CS without encountering it in any of my courses, I think it's safe to say git is much more ingrained in the field now (pretty much every syllabus I come across online for CS courses from the last 5 years has had some github links)

SVNs heyday is closer to 15 years ago at this point.
