Well, I don't know what "worse" means in this context. If it means "less memory safe", that's clearly not true: RefCell and Mutex are formally memory safe, while the C++ equivalents are not. If it means "less correct" in a more vague sense, then that's essentially an argument that Rust programs have more bugs than C++ programs, which seems dubious and certainly not something I'd accept at face value.
