I'd compare it to the time investment in vim or emacs. Getting some basic stuff done is unlikely to be difficult. (e.g. using `nix shell nixpkgs#fd` to try out the `fd` tool). Getting a solution to a problem you have right now might be a quick copy-and-paste effort, or it might be a weekend's worth of tinkering to get even an unidiomatic solution. Gaining familiarity with it does take a long time though. Most NixOS users will be modest about their confidence in writing Nix code (albeit, most NixOS users are also very passionate about the advantages of Nix & NixOS can be).
