I have a serious question: If Emacs has a lot of the features people seek in Neovim, why not just use Emacs in evil mode? I watched this earlier today so it seemed relevant: https://youtu.be/JWD1Fpdd4Pc

Side note: I've been using Neovim for months now and I've not tried Emacs. Not because I don't want to but because Vim with the plugins i have works really really well.
