Claude Code uses Bun written in Rust now
The captured headline says Claude Code now uses Bun written in Rust; the HN comments debate the rationale, engineering trade-offs, and what evidence would show the change works.
Why it matters: Treat this as a reported change, not a demonstrated performance or reliability improvement: commenters ask about RAM, CPU, dead loops, deadlocks, and upgrade reliability, but the capture gives no measured answers.
