I think it’s the majority, still. Not sure if that’s technically changed to KDE with Steam Decks though.

Yes. Yes we are.

That probably won’t work by default because ulimit sets maximum processes per user, but I haven’t tried it recently, or with emacs.

Hmm, I didn’t expect that last one.

Very fair point, thanks.

While you are correct in that macOS primarily isn’t composed of tools that “do one thing well”, macOS is still UNIX-certified under the Single UNIX Specification (identical to saying it’s POSIX-compliant and X/Open Curses compliant) and is literally a UNIX system. Most Linux and even BSD systems are not UNIX these days, though I’d say a higher proportion of their tools/components follow the UNIX philosophy.
