Seems someone's so unhappy that #vim and #neovim accept AI-assisted contributions that they forked vim https://codeberg.org/NerdNextDoor/evi/issues/1
Seems like a somewhat pointless uphill battle to me. If the contributions are of high quality and solve real problems they are perfectly fine in my book. It's not like the number of C, VimScript and Lua experts has been growing a lot in recent years. ;-) AI agents might help make some niche technologies less niche, which is not a bad thing...
