(Copying my comment in programming.dev:)

It is very interesting to see how with Rust and Guix, there is some convergence between programming worlds which so far have been rather separate universes. For example, Rust makes it easy to write modern system libraries which previously would have been written in C, the Linux kernel is slowly adopting Rust, and Guix makes it easy to use such libraries in strong-dynamically typed languages like Guile, Racket, or Python.

For the general programming community, the promise is that Guix kinda solves the packaging and dependency resolution problem for multi-language projects. And it is making good strides - Guix contains over 50,000 packages now, not counting the nonguix channels which add e.g. non-free firmware. (Just for convenience, here how to install the Guix package manager im Arch).
