That’s a subjective take. GNU Nano has always been the default editor for so long alongside vi. But when you say that Emacs keybindings are good for Mac user - I can’t help but wonder - what type of generalization is that? Do you have a source to back this claim?
Now, don’t get me wrong - I love Kakoune. But no one outside of the developer community will make an effort to learn atypical text editors with chords and modes.
