Ask HN: Can you show me how fast coding is in vim?

I have tried to learn vim, and I am on the fence about which editor to use. I have tried Atom, Eclipse, Emacs, etc. VSCode just came out and Facebook has its Nuclide editor on the shelf. People hold vim as a pinnacle of editing technology.

Can you show me with a short screencast why vim is superior? And, why it is worth spending the time to learn, not only mentally and visually, but also mechanically with my hands.

Thanks.
