> At what point does a C++ programmer like yourself just switch to something that advertises safety but also C like performance?

As a former diehard c++ developer, modern c++ was the reason I started learning Rust.

All the good parts of modern c++, without any of the legacy baggage holding it back, and avoiding all of the things that made modern c++ necessary in the first place.

I still program in c++ professionally but only for legacy programs. For anything new I would avoid it in favour of a modern language.
