The "just use Nix" people are just like the "write it in Rust" brigade.

And the things both groups promote share exactly the same problem ...

A stupidly enormous learning curve.

That's why your average person prefers to just the job done in a container vs Nix, or in Go vs Rust.

I'm sure Nix is awesome, just like I'm sure Rust is awesome. But honestly, I've got enough going on in my brain at $work and $home without having to wrangle some obscure config syntax (Nix) or obscure low-level language complexities (e.g. Rust's infamous borrow-checker).

Every time I go back and look at Rust or Nix my brain is just like .... no, thanks.
