I really dislike Nix/NixOS, but I think it's kind of unreasonable to claim something is unappealing because of a learning curve. Pretty much everything on the planet has a learning curve; if a project is genuinely innovative or aiming for a paradigm shift, and you find the benefits of it worthwhile, there's probably always going to be a learning curve.
That said, are we really reading the same post? What's presented here is...really simple, and you should be pretty much familiar with most of it if you actually set up Gentoo and Arch in the past; pretty much everything directly translates that requires user interaction in this, and the package format is pretty similar to write & read, too.
