As someone using nix because I messed up my arch luks encryption because of single command on stackoverflow..... I haven't really learned nix os language right now and I have only installed bare minimal software like a librewolf, prism launcher, kde, I used to be a hyprland user and I might switch back in some days. The biggest advantage to me feels nix-shell which is cross platform I installed obs-studio from nix-shell, built a video, then used another nix-shell for ffmpeg and converted video to mp4 and uploaded it to github. This is my general use case of obs and I very rarely make recordings and so this idea that I can install/try out software without having to worry about anything while still having no xdg issues unlike flatpak is a godsend. Did I mention I started using nix-shell for places I would've used docker, like stirling-pdf one off cases Most of the software on my computer needs to be rarely accessed and I love the sanity that nix provides knowing that It won't make my update times faster/if-any unlike archlinux and dependency hell is a problem I truly despise. I have looked for better alternatives, maybe spack comes to mind, but nix-shell is still crazy good. And I can also some day use a functional programming to make it even more automated.
