So the "Bun being a vibe coded rewrite from Zig to Rust" is a different story than I think it's being sold as, from everything I can see. It's worth seeing several events laid out back to back.
- Zig has a no AI contributions policy. They've explained their rationale: https://kristoff.it/blog/contributor-poker-and-ai/
- Bun has a fork of Zig with AI generated changes. Zig's developers explain why they aren't merging them, and that they have their own path to relevant improvements https://ziggit.dev/t/bun-s-zig-fork-got-4x-faster-compilation-times/15183/19
- Anthropic acquires Bun https://www.anthropic.com/news/anthropic-acquires-bun-as-claude-code-reaches-usd1b-milestone
- Bun is working on an experimental rewrite from Zig to Rust using Claude driven by the Bun lead, now working for Anthropic https://news.ycombinator.com/item?id=48016880
What does Bun's lead have to say about AIgen contributions to FOSS?
> I expect OSS to go the opposite direction: no human contribution allowed. Slop will be a nostalgic relic of 2025 & 2026.

What can we make of this?
