Are you replying to the wrong comment? I clearly quoted which part I were replying to. I didn't attempt to answer the question "why write Bun in Rust when CC itself can be written in Rust."

What I said is that "they know that LLMs are not the right tool for this" is not the answer, as CC is already vibecoded so it'd be very weird to believe you can't vibecode a port of CC.

The actual answer is, of course, the whole discussion is just making a hill out of a mole. Bun is not committed to a Rust rewriting, vibed or not.
