I was a vim user for years. I accepted a challenge from the programmer who sat next to me (an emacs user): we'd swap editors for a week. Every time either of us swore or complained about the editor, we'd pay the other a dollar.
That was 2011. I've been an emacs user ever since.
Jokes aside, during the 1 or 2 weeks that I forced myself to use emacs (a few years back), I felt that I would get RSI because of the painful default keybindings. Of course, I didn't know of evil back then, so I returned back to using vim.
