I'm using Fish for years, tried Nushell recently, but it didn't click for me. While I like the principle of data being more than just plain text, it probably was just too alien to me.

A few here said they don't use Fish or another shell due to compatibility issues, but I wonder what the problem is: If I want to use a script written for another (POSIX) shell, it most likely has a shebang (or I can add it), so it will get properly executed using that other shell…
