One thing about the PC architecture (and that's very specific. PS4 is not a PC even though it's x86. You can't boot it like a PC and most of the hardware is ass crazy) is the standard made running Linux incredibly easy. Sure your video or audio or phone-modem might not work, but it would almost always boot to console.

I really worry about Linux getting left being with the Apple/M* or Microsoft/ARM offerings. You can take almost any Lenovo/Dell/HP offering and there's a good 80% chance all the hardware on it works with mainline Linux (unless it's super new and has like Wi-Fi7 or something). I don't want to see us getting to the point where Linux users are having to get very specific lappys just to run the OS we want.
