My comment on Emacs is a bit flip - but it’s based on what I’ve seen and from my biased vi-using POV. Almost every IDE or developer-focused app I use has some sort of Vi keybinding either available as a plugin or built-in. And they’re often pretty good. Even joplin which is a note-taking app has Vi keybindings built in (though to be fair it also supports emacs keybinds).
If anything Vi keybindings have become more popular over time not less. “back in the day” getting any sort of Vi keybindings working with IDEs was either impossible or painful and limited. These days it’s a checkbox. The nice thing is I can take a good sub-set of the Vi bindings between many editors and IDEs. Ideavim’s implementation is quite good and even supports vim macros which are amazing once you get the hang of them.
