I'm on year 6 and still feel the same way, using NixOS for all my machines, and also for my homelab servers (building on the main machine and then deploying over SSH). Everything else feels primitive by comparison. Rolling back is incredible.

I have one github repo with a top-level flake containing system definitions for all of my machines. Much of my config is modularized, so it's easy to take custom stuff from one machine and use it on another.

It's nice to hear that AI tooling is making it more accessible for people.
