As expected [0] [1], this was a clear advertisement / marketing opportunity of Anthropic's Fable model on rewriting Bun (which powers Claude Code) from Zig into Rust.

Now Claude, rewrite Claude Code from TypeScript to Rust. Make absolutely zero mistakes.

Not really and we both know that is not true.
The last line of the comment was the joke. [0] It is clear that you didn't get it and many others did. That is OK.
Heavens forbid anyone here is allowed to make any jokes on this site.
