And who is to say that the programmers of Rust built a perfect language that always generates code which is bounds-safe? I question that as I know from experience that no human has ever written 100% correct code 100% of the time; even machines aren’t capable of achieving that. Therefore, I hold that the entire promise of Rust is flawed. I don’t like Rust one bit.
Perhaps neon green with yellow letters would do the trick?
On the other side there are proper languages which do provide all safeties and beat rust or C++ in performance, such as pony. A proper type-system does help (compile-time guaranteed), but you could also add such features to the run-time system (e.g. a GC or safe threading with a single-writer system such as parrot). With rust you don't have any of it, you have to manually add locks or mutexes into your threaded code, and try to avoid unsafe.
