Oh god I hope not. Having worked in > 100kloc nix environments I am completely turned off of the idea. I really really tried, I installed NixOS as my main OS and used Nix whenever I could to try and pick it up, but it's such a complex beast I felt it slowed everything down. Simple tasks that would take 10 minutes in Docker suddenly became DevOps tickets. I suddenly had to write bindings for tools rather than apt-get them in a Dockerfile. Build times in Haskell were bad enough but suddenly you had nix into the mix and I'd be wasting half a day as Nix built the entire world - solved with internal caching servers but have fun trying to work out how to push something to that correctly.
