of course!

you’re definitely right about needing to be a particular type of insane for Nix to fully click, and I’ve seen enough people bounce off of it that I try to make Nix optional (but very nice to have) wherever I can

with that said, there are a few areas where what Nix does is irreplaceable. broadly, areas like deployments (devops), embedded development (where Nix’s methods of cross compilation and target configuration are much saner and more reliable than average), and developer tooling are where it’s extraordinarily difficult to replicate what Nix provides, and those are also the areas where I’ve personally seen the most production usage of Nix.

I don’t personally coordinate a professional team that uses Nix, but it might be worth looking up impressions from companies that do. to my memory, two companies I know use Nix heavily are Pololu Robotics and replit (which uses Nix as a user-facing part of their developer tooling; fair warning though, last time I looked they were heavily enshittifying and pushing a bunch of AI shit).
