Yeah, I think it’s a fair characterization, I just wanted to clarify that it is indeed based on Unix. To my knowledge I’ve never used BSD. I didn’t move away from Windows until I, like you say, just didn’t have the bandwidth to do more than one experimental thing with my computer. Windows pushed me out a few years back, and I went with Linux because of the breadth of support. I’ve got tons of time to do research, though. By which I mean read random Wikipedia articles in the bathroom, TBH. I found a big tree somewhere on there a long time ago, showing the progression from PDP Unix all the way to the latest FreeBSD (with Linux as a little tag on the side, lol).
