I don't think that was the case for me at least. I felt like (using your own analogy) the more I studied Rust, the better I learned how to use every other hammer. Learning a new programming language helped me learn c++ better since I was constantly on the lookout for potential memory leaks and other common pitfalls that Rust prevents. Now when I code in c++, I always try to write the code with safety in mind.
