At one point, sooner or later, you have to tell them they just need to learn the language.
I'd rather spend time explaining the language than teaching them workarounds.
Having said this, we already do have ways to dodge the language for example using imperative package management. But that's exactly how another such blog post could be written how it doesn't always work due to "freedom" that Nix tries to provide.
Lesson learned here is: pick your fights carefully.
