The issue with investing similar levels of effort into making C++ safer is the C++ standards committee doesn't want to adopt those kinds of improvements.

I am not interested in C++, it is also far too complex. In my opinion software needs to become simpler and not more complicated, and I fear Rust might be a step into the wrong direction.

Which is also the reason why we don't have #pragma once and many other extensions like it. Except we do. Compilers can add rust-like static analyzers without the standard committee mandating it.
