> Nix is just another chef, ansible, cfengine, apt, pacman

No, because Nix code is actually composable. These other tools aren't.

[JamesSwift]

Not only is it composable, but it is generalizable. So yes there is also chef, ansible, apt, uv, nodeenv, etc... or there is just nix. It is able to be the "one tool" to rule them all, often with better reproducibility guarantees.
