I used to use visual studio and I think I maybe also learned some very basic vim (arrow keys, i, dd, p, :wq) to do some remote sysadmin type things. I wanted to learn Common Lisp which, at the time, meant having to learn Emacs too. And then I was more interested in things outside of windows and Emacs stuck. (Also the calculator in it is amazing).

Funnily, I also work for a company where many people use Emacs (it was the only editor with good support for our tools for a long time – you can even order lunch from it – new hires were encouraged to use it, even non-software engineers when they needed to interact with the Linux side of things) which I think is pretty uncommon. There was definitely a time 10 years or so ago when vim seemed to have massive popularity online and everything else seemed to fly under the radar.
