Replaces the Archwiki with basically 0 docs

Arch wiki is still relevant, I still use it as a reference on my NixOS box.

a large chunk of your Linux knowledge no longer applies

Your pacman and pacur (or whatever the name of the air helper soup de jour is this week) will no longer apply. Most of my linux knowledge was still applicable. You have all the same programs that run in the same way as they do on arch.

you can't compile from source

Sure you can. Want to compile everything from source? Just turn off using the cache. NixOS is a source based distro.

everything is different

Also no. I use the same programs I can get on most other distros.

the nix language kinda sucks until you "get" it, etc.

If you have ever used another functional language its fine.

After nix there is only sadness

It is better in all the ways. Newer packages, no imperative config, reproducible.

nVidia drivers on NixOS are easier and more pain free that on any other distro I've used.

Good now wipe it and install NixOS. You're ready.
