You are indeed technically correct, sir or madam.
To be honest, if Linux magically disappeared I'd just lean more heavily on using my Android devices.
At least for now, there's more capacity to have primarily FOSS on Android than on Windows or Mac.
I expect that will change with time and Google wearing away at the systems, but right now you can install a FOSS rom and have the majority of your apps from F-Droid, and the equivalent isn't possible on x86 devices.
Watching the various Linux for ARM projects with great interest to hopefully take over when Google eventually ruins Android too.

I was considering giving NixOS a go. What are you finding difficult about it?
