Nix will not overtake Docker because 1. The overlap is not that big 2. Nix has usability issues That being said Nix even with its usability issues works better for reproducible development environments than anything else (including Docker) ATM. Therefore in my view either Nix or something very similar will be the solution for this and replace Docker (some people run builds using Docker containers) for this use case.
