I think the language is harder but more powerful than Nix’s.
Imo a better manual and examples would help a lot.
I’d say one of the biggest issues is the one with proprietary drivers - you can’t really find examples and guides on how to get drivers working because it’s kept hush-hush, and to install them yourself requires knowledge on how to set things up, knowledge which beginner users don’t have ofc.
I’m a big fan of Guix and Guile but atm I couldn’t switch over due to this.
