I learned (neo)vim this last year. It really wasn’t that bad. You need to learn like maybe a dozen hotkeys to get going, but after that you can do :h <topic> for everything else. And it’s not even like you lose full functionality of your mouse, at least neovim supports a lot of mouse movements

My 3 year old is obsessed with it. He’ll randomly come up to me, say siiiix seeveeen and then run away giggling to himself.
