Are you kidding? Just one very obvious example: Rust has had good interfaces for std:: optional and std::expected since v1. C++ is finally getting them in c++23 and c++26 (maybe) respectively.
Moreover, you only have to learn Rust once because the language doesn't have nearly the same number of weird limitations and radical overhauls every 3 years. I attend the conferences and write C++ regularly. I still run into issues when reviewing teams where I have to consult the standard because I'm not sure if some weird construct is valid because everyone has their own subset of C++ they're comfortable with. God forbid you have to onboard someone new to the language and explain all the different kinds of initialization, a topic that's utterly trivial in literally any other language.
As an aside, static code analyzers are not able to provide the same kind of guarantees rustc does to arbitrary C++.
