AFAIK, the design goals of Rust are better security and correctness in general, than C++. Have you looked at Rust and decided that it does not achieve that goal?
If someone hires me to work on a project, in the current state of affairs, they're much more likely to have picked C++ than Rust, and I don't get the choice (other than choosing whether to take the job). Rust doesn't (yet) open that many doors for me as an employee.
