Vim's model of modality and mnemonics is a beautiful, powerful, amazing paradigm. Here's the thing though - there's no such thing as the "vim-mode". None of the IDEs and editors like IntelliJ, VSCode, XCode, Android Studio, Sublime, etc., can properly emulate Vim navigation. The one exception is Emacs.
Pretty much every other IDE fails to comprehensively replicate Vim. Unless it's Vim/Neovim, vim-mode in all of them is just that - an emulation. However, Evil mode in Emacs feels much more natural. Sometimes, you forget that it's an afterthought, an extension, and not a built-in functionality.
Just that alone speaks volumes about the extensibility of Emacs.
While Evil-mode (the Extensible VI Layer for Emacs) obviously is not the most important or even built-in feature of Emacs, as a nerd and a computer programmer, if I discovered that there's a civilian plane that can perform a vertical landing, yet never actually needs to use it, I would still love that model over any other planes, even if the feature is purely accidental. The fact that it can do so alone would be great evidence of amazing engineering.
And as a die-hard Vimmer, one day I had a revelation - I realized that Emacs vims better than Vim and Neovim. While also opening possibilities for many, many other things.
