I’ve contributed both to NixOS and surrounding ecosystem.
Evidence:
Learning cliff rather than curve because:
The state of the documentation should have been unacceptable a decade ago. Very unacceptable now.
The tooling is also over a decade behind.
Governance leaves a lot to be desired.
These things are getting better but not fast enough that I’d recommend it.
If you really want to look into nix, use it on another distro and see if you’re still interested after getting a flake-based devshell together. (impossible challenge: do it for a python project that relies on complex dependencies like transformers)
