I could go on and on about the limitations of min_const_generics, missing TAIT (type alias impl trait), unstable coroutines/generators, etc. but none of that stuff erases how much of a miracle Rust is as a language. The industry really needed this. It's practically the poster child of memory safety and security-critical industries are picking it up and Ferrocene is pushing it in safety-critical environments as well and it's just. Good. Please. Finally a serious contender against the terrible reign of C and C++.
