I tried to switch to nushell full-time but couldn't stick with it.

Ironically, the main friction point were not old-fashioned tools (which `from ssv` usually handled nicely) but the 'new generation' of core CLI tools like eza or fzf. They have really nice visualizations, but they do not output structured data as a middle step, so all the colours and lines only play havoc with nu's parsing.

Since I need to "ls" a lot more often than I need to do data manipulation, the tools won and I went back to zsh. Still keep nu around for the occasional config/data file wrangling though.
