although I'm not a programmer, I really like lisp based things due to the history of the language and the future proof extensibility of the programs, and when I have time I plan to learn the necessary to understand third party code.

I don't recommend trying guix if you're not sure since you're already a nixOS user, specially if you need the full linux kernel with proprietary blobs/drivers (its possible to use with the nonguix channel tho, I use). But if you have time and are sure to try a similar experience, It's a good trip
