Nitpick, but I love vim (and to a lesser extent emacs) and am not a programmer (sadly). I don't believe you need to be a programmer to use them. Using vim is "just" using your computer. Personal notes, system configuration (dotfiles), anime playlist management (.m3u files mainly), checking the name of a unicode character I don't recognize (vim-characterize), inverting capitalization (select and hit ~) or making large formatting changes to some text (block select visual mode and multi-line editing, macros) to post elsewhere, bulk renaming of files (vidir), writing emails (aerc), vim is my go-to for all that. That's not even getting into vim-inspired separate programs like ranger and qutebrowser.
