It’s a good troubleshooting tool. Pasting in weird error messages that don’t turn up any useful search results is pretty useful, even if the response it gives is partially inaccurate, it usually at least gives a bit more information than a search engine, which gives me more context to narrow my search terms and find a solution to the error.

It’s especially useful for learning Nix, since the online documentation is a bit shit and ChatGPT seems to have enough grasp on the Nix language and how to configure things in NixOS to tell me what I’m doing wrong.
