I'm in this school of emacs usage. I use Aquamacs on my Mac and while I've been using Emacs for almost as long as kabdib, I've barely scratched the surface of what Emacs can do. For me, the biggest thing that'll get me to drop out of IntelliJ (I was so happy to learn that there were Emacs keybindings hidden in one of IntelliJ's Mac keymaps) and into Emacs is to do ctrl-x(...ctrl-x) to record a macro, then ctrl-x NUMBER ctrl-x e (I'm hoping I'm translating muscle memory correctly) to do a repeated complex edit on a block of text. It's always fun to see junior devs (and occasional seniors) watch me do this and ask, How did you DO that?
It's fun to see someone's jaw drop when you show them what you can do with a keyboard macro, some regular expressions and a little shell integration.
More than simple fun; I've saved people from hours and sometimes days of drudgery with just a few minutes of mucking about in Emacs. Teaching someone simple automation is pretty rewarding. Even if they are not technically capable of repeating your solution, at least they go away with a problem solved AND the knowledge that there are usually better options available than drudgery.
