It's not about the code or the use of AI. It's about the governance of the Bun project.

Nobody knows if the Rust AI rewrite was a good decision from a technical pov. We do know it was a unilateral and drastic decision taken behind closed doors and imposed onto all Bun users.

There was a poll on r/bun where only about 30% of users said they were going to use the Rust port.

Even worse, users on the Zig version have been pretty much abandoned. Any future bug fixes, security patches, etc will only be released in the Rust version.
