Nix and containerization aren't drop-in replacements for each other.

You can use Nix to build containers. Containers on their own don't guarantee reproducibility, especially if the build process isn't static and pure ( how many times do we `sudo apt update` inside a Dockerfile )?

And not everything is going to be containerizable. That only works for most applications. What if we're trying to manage our cloud servers? That's where Nix really shines.

Do you really think that Nix developers don't know how to containerize applications? You think people are using Nix because they refuse to learn how to containerize, and therefore opt to learn a _much more_ difficult and arcane build process? The logic doesn't track there.
