Version control was always something that was adopted more by process-heavy organizations until the popularization of GitHub. Before that, it was common for the move-fast type of developers to eschew version control.
Earlier in my career, people didn't bother with the chore of using version control unless they were working on an important project that demanded it.
Idk, I feel like the difficulty of Git (which is real in some respects) has long been exaggerated by people who are categorically unwilling to RTFM.
Some slight rigor shows you are not just doing whatever. I found most projects once you scale past 2 or 3 people and your 3rd release you basically are forced into some sort source control. Or it is a game of 'what file did they break today and I have to spend 3 hours fixing before I can add my feature'. Then you end up with merge meetings and very weird things happening.
Usually missing source control in an older org means there is a large swath of tech debt. Watch for the weeds. You will find other things very quickly.
