This is a very bad take. Rust does solve very real problems in C family languages. The number of people I met in Rust conferences that rewriting at least parts of rather big C++ codebases weren't small either. However, there is still big amount of code that is purely C++. Many of the older code bases still use C++03-style code too. Or they were written in the OOP design pattern golden era that requires huge reactors to adapt functional / modern code. Anything with Qt will not benefit from smart pointers. Even with Qt 6. Rust cannot solve these problems since the challenges are not purely technical but social too.
