Using containers and std::string for everything eliminates the majority of safety bugs.

The safety bar is way way higher.

The C++ WG keeps looking down at C and the old C++ sins, sees their unsafety, and still thinks that's the problem to fix.

Rust looks the same way at modern C++. The std collections and smart pointers already existed before the Rust project has been started. Modern C++ is the safety failure that motivated creation of Rust.
