No way. It’s still a specialist OS. There’s no way I’m putting this into the hands of a linux newbie or even the average linux user. There config still doesn’t have a UI, the flakes vs non-flakes debate is still in full swing (nixpkgs doesn’t have flakes), the doc is far, far, far from user friendly, writing a nix package is still not easy, and so much more.
Nix for sure was (and probably is) ahead of its time, but the UX is amongst the worst I’ve experienced - and I’ve written init and upstart services and configured my network with ipconfig before networkmanager was stable.
