I mean, I'm still on Yosemite, and I didn't even want to "upgrade" to that (but had to, to use the iPhone 8 I bought). I would rather have stuck with Mavericks. Every new macOS update seems to bring new freedom-limiting changes which I fundamentally disagree with, and it's getting harder and harder to justify using such a closed platform...

Stratechery's mention of what hackers/programmers move to as being an indicator of what's next is interesting, as currently it feels like these types of people are largely moving to more open platforms. I see it all over my social networks where super talented engineers are embracing not only open software, but open hardware, too... We shall see, I guess.
