    Guys… it’s over. They found out. Rust is not 100% safe. Time to re-rewrite everything in C.

    Don’t rewrite in Rust. Rewriting for memory safety is similar to premature optimization: it’s focusing on something that doesn’t give the most bang for the buck. Old & battle tested C/++ have few memory bugs. Most memory bugs exist in *new* C/++ code. Write NEW code in Rust.

    A space exploration game, where you discover that outer space is too far from the origin, and you start getting float32 precision problems

    C is a bad programming language *and* a lot of software we rely on is written in it. Both can be true at the same time.

    In Rust it’s called .unwrap() because runtime crashes are a gift
