> w.r.t unsafe languages: it's not even possible to instrument and operate hardware in a "safe" way, even rust which is rather low level needs to be wrapped in unsafe in order to interact with hardware. Like you just said: security doesn't have to be boolean. Using more secure languages doesn't mean we have to completely banish every occurrence of unsafe in Rust. It just means we should avoid languages that force even business logic to be written using pointer arithmetic.
