Vim, the text editor, might be relevant if you want a powerful text editor that's installed on basically any *nix system ever. Nano has become nearly as ubiquitous so it's unlikely that you'll need to know vi/m on most hosts these days.

Vim, the editing paradigm, is a relevant skill if you value trading time to learn a way of editing text that is vastly different from traditional. It's a faster way of editing that once you grok it will probably make you annoyed about editing text in editors that don't support it. VS Code has a pretty good vim implementation, though. I personally think it was worthwhile, but people value different things. You might not like the investment of time it takes to become proficient or may not find it as useful as I have.

I can't speak to what is the state of the art for Lisp development. I'm confident that you can use editors other than Emacs or Vim for it, though.
