> Are there any other advantages to using nix?

The advantages are more pronounced for DevOps than for developers.

e.g. for DevOps, Nix allows copying a package of software (and all its dependencies) from one computer to another, with confidence that the programs will work on both machines.

For developers, Nix is more appealing if you ever work on more than one computer. e.g. with Nix, it's easy to ensure you've got the same version of packages installed regardless of whether you're on macOS or Linux.

It's pretty neat for side projects, in order to get "I was able to build it now, I'll be able to build it in 6 months". Whereas, if you're otherwise relying on Ubuntu's system packages, maybe the package versions got updated, and so you'll need to spend time to get your program to work with the latest compiler/libraries.
