I've found nixos is perfect for me since I like how precisely I can configure it.
Oddly enough, I've had a decent chunk of my only barely technical friend group switch to it for the opposite reason. They all just copypaste snippets of config between each other, and if something breaks they just go back a revision. I doubt any of them spend much time configuring anything. It really is the perfect idiot proof distro and I don't normally see people talking about that side of it
Yeah, I think Nix is a good concept but I feel like 99% of the config work could be managed by the OS itself and a GUI to change everything else. I also feel like flakes should be the default, not this weird multiple systems thing they have. I also wish most apps would have a sandbox built in, because nix apps would then rival flatpak and, if ported to Windows, become a universal package manager. Overall good concept but not there yet.
