It took me a single afternoon to learn the basics and start using it. Contrary to what I initially thought, I didn't have to migrate all of my dotfiles at once. Then over the next couple of days, Codex migrated everything else for me.

One major benefit for me is that I no longer need to have once-in-a-while tools installed, because I can always spin up a temporary shell with `nix-shell -p packageName`. This significantly decreased the amount of software I have in my environment.

This works great with agentic coding. Agent wants to run `ripgrep`, but you don't have it? Tell it to run `nix run nixpkgs#ripgrep` instead.

But the biggest benefit is that now that you know Nix! So you can start using it to create reproducible development environments and uninstall mise, asdf, nvm, pyenv, etc. You can spin up reproducible servers running NixOS and never touch Ansible again. You can even install it in your router.

Or you can do none of that and continue just using it for your dotfiles. It plays nice with other tools.
