They don't hate it. There's no antagonism that I know of there. I believe they want it to be fully human-authored and want low-hanging fruit items to be good onboarding for developers, not targeted by AI contributions. Simon Willison wrote a good blog post on it: https://simonwillison.net/2026/Apr/30/zig-anti-ai/

The Bun pull request was refused for additional reasons: 'AI is entirely beside the point here...': https://ziggit.dev/t/bun-s-zig-fork-got-4x-faster-compilatio...

None of this is, in the original comment's text, "hating... AI".
