An update on Bun’s experimental migration from Zig to Rust:

The Rust rewrite now passes 99.8% of Bun’s pre-existing Linux x64 glibc test suite.

If true:

   Green light for the rewrite-it-in-rust and pro AI crowd.

   Amber light for the bugs that are in the rust rewrite.

   Red light for the 100% anti-AI folks.

Unfortunately, when to someone takes the absolute position of hating something such as AI and progress; there will always be someone else that is determined to turn that into marketing content and attempt to prove them wrong.

Anthropic is not only doing just that, but won't let the Zig community stop them even when they used Claude to improve the compiler (and have checked the code themselves) and will use this opportunity to market Claude to migrate Bun from Zig to Rust.

6 days of work to do this. Even if it doesn't end up becoming meaningful, it shows just how tokens and work done will be linked now and in the future.

It's going to be hard to compete with someone or a company that has more compute. They will just be able to do things you can't.
