I started using Linux in 2016, I stopped distro hopping with arch and I’m using it since 2019. But I’m looking forward to try nix like OSes like guix. I see the value of it, it’s just too much hassle right now. Meanwhile I’m using aconfmgr for tracking my modifications in my system.

I use rust only if we need performance, for small services. The industry does the same. People use node for backend but e.g. redis is in rust. It’s a good tool if you use it for the right stuff.

EDIT: redis is not in rust, but e.g. aws writes many services in rust
