I certainly echo that it's a bit of a curse because as soon as you go off the happy path you start needing to learn the internals & the language neither of which are particularly easy. That being said, the rollback capacity, the ability to include a deterministic set of software needed for any particular software project (the inclusion of shell.nix or build.nix in a repo) is one of the few new pieces of technology that I'm unambiguously excited about becoming wide spread. It doesn't feel like it carries a dual use problem like AI or cryptocurrencies.

This could mean the first time you want to use something that isn't inside nixpkgs, which to be fair has now overtaken AUR to be the biggest single repo of packages: https://repology.org/repositories/statistics/total
