53 days after Cloudflare announced that their service was now “more secure” because they had ported it to Rust... an error in their Rust code caused a massive outage.

Rust protects you about memory use error, on all the other errors you are on your own. I once wrote

> something_something(a, b, 0)

instead of

> something_something(a, b, 1)

No compiler will detect that. Maybe an AI review, but it was like 10 years ago, before the AI era.
