I have always struggled a bit with shell replacements. I use zsh but only because of oh-my-zsh. Apart from that I always thought of shell scripts as a necessary evil for interoperability. Today you can usually expect a linux system to have bash or at least sh. That is why I do shell scripting. Nushell is usally not preinstalled on a system and so I cannot expect it.
If I want to do real scripting/programming I use python or another dedicated programming language. I don't really know what the value of Nushell is for me. Maybe the plugin system is amazing but at the moment I miss nothing in my zsh.
