Absolutely zero requirement or expectation to be technical is the biggest one IMO. For example you don't have to know or care what an operating system is or does to use macos, which is a lot less congnitive load. And some Linux based OSes solved this too, like ChromeOS and Android. One of the big value props for specialization in civilization is that you can just worry about your own thing - like idk how to fix a broken down NYC subway train and I don't really care as long as someone does. And Linux pretty handily wins in server land where the users have specialized into being technical and that's their job.
