I find this part very compelling

    vi basic grammar is verb followed by object; it’s nice because it matches well with the order we use in English, "delete word". On the other hand, it does not match well with the nature of what we express: There is only a handful of verbs in text editing (delete, yank, paste, insert… ), and they don’t compose, contrarily to objects which can be arbitrarily complex, and difficult to express. That means that errors are not handled well. If you express your object wrongly with a delete verb, the wrong text will get deleted, you will need to undo, and try again.

    Kakoune’s grammar is object followed by verb, combined with instantaneous feedback, that means you always see the current object (In Kakoune we call that the selection) before you apply your change, which allows you to correct errors on the go.

Unfortunately, I'd rather see this as an alternative input mode in vim/vscode/nvim than separate editor, so I won't need to throw away all knowledge/plugins/dotfiles accumulated over time, than switching to completely new editor. Baggage is hard.
