I’ve seen too many embedded drivers written by well known companies not use spinlocks for data shared with an ISR.

At one point, I found serious bugs (crashing our product) that had existed for over 15 years. (And that was 10 years ago).

Rust may not be perfect but it gives me hope that some classes of stupidity will be either be avoided or made visible (like every function being unsafe because the author was a complete idiot).
