• Nix will never replace arch. Arch focuses on a KISS philosophy, whereas Nixos Isn’t that. But as an Arch user, I do enjoy nixos, because hacks and tape is done on in a standardized language, all in a centralized, easily searchable, understandable, and editable repo. With arch, it comes with no hacks and tape, so you apply them all yourself. They are very different distro’s, but they often appeal to the same kind of person.
