Interesting points, I've definitely run into memory constraints which resulted in completely unresponsive hosts a few times over the years. But as the author said, I don't see this changing within any another of time due to the large scale archetectural changes required...
The author also mentioned "I’m tempted to abandon using Windows, macOS and Linux as the main platforms with which I interact.". Does anyone know which "daily driver" compatible operating system the author could be referring to?
FreeBSD? Gentoo? There aren't really that many options that are maintained depending on their definition of Linux. Might as well not use any computers at that point because you'd be on TempleOS with no internet and barely any colors.
I have never even looked at it before so I just did. It is. It looks more complicated than arch. But everything compiles locally which for some reason swoons me. I just got into Linux 2 uears ago, and just got on arch. So that may be my next target.
It's anyone's guess, really. I can think of a few "exotic" OSs, like Solaris, Haiku (BeOS like), AROS (Amiga like and compatible), Kolibri and Risc OS, but I doubt the author would use any of those in any capacity.
