Recently, I recommended to a friend that basic vim/vi is worth learning because it’s a baseline that you can always trust will be there across different Linux systems.

They asked me what I used most on my home system, and the answer was emacs, but I was very clear that I was not recommending it. It’s a particular kind of person who finds themselves at home in emacs, and for everyone besides those people, selling them on emacs would feel like persuading them to do hard drugs.
