Until people routinely use a RefCell equivalent in C++, abandon APIs like string_view, stop mutating directly through shared references, and stop using multiple threads (or C++ somehow finds a way to encode thread safety into its type system), most C++ programs that are memory safe are only so by coincidence. The whole point of Rust is to make memory safety a locally provable property, and even modern C++ has far too many idioms that abandon that local provability to make global memory safety feasible in large programs.
