C++ has much more bigger inertia. It is like the "default" for all the areas where it is being used. So when learning a language people would rather go to C++ first and then to Rust, if they are really planning to work in corresponding area (game dev etc.). Or even go to C. Rust will probably replace C++ in some areas where it is a legacy app (or part of the app) that is not changed frequently anymore.
