Not the grandparent, but from what i can see, grandparent compares Nix with traditional package managers like dpkg or RPM, rather than Guix.

I cannot answer your question, but I think Nix has (for some reason) a lot more publicity than Guix at the moment.

[joepie91_]

Guix is derived from Nix, so that might be why.

If by "derived" you mean that it is another implementation of functional package management, then you are right.

But if "derived" implies that Guix is a fork, then you are mistaken.

Guix is not a fork of Nix.

[xwvvvvwx]

Guix is built on top of the nix daemon, so while it's not strictly a fork, derived seems fair.
