To be clear, I understand the appeal of Fish and its reason to exist. It's just I convinced myself that the standard shell should be POSIX compatible (had used ZSH for years too, before trying out Fish). And frankly, I am good enough in Bash for daily use and for scripting, that I can use it. Every time I look at Fish (to almost try it again), I'm jelious about some of the syntax and trap cleanups and features. Maybe one day I change my mind. I actually have plans to install Fish again and see how it goes.

Nushell is really an interesting one. This is how I imagine a modern shell should be like. But the reality is, that all the Linux tools and commandline are not based on this concept. That's why I never got into. And Xonsh, well I write Python too, and not sure how confusing that would be... I just brought up these shells to make a point about Fish being different and that I categorize it like those.
