There are some similarities, like the module system, and the "self" convention for methods which in Rust is a keyword.

At some point the similarities with Python stop and the similarities with C++ start. Although without the sins of C++ (like decades of backwards compatibility going back to plain C), which greatly reduces the decision fatigue you get as a C++ developer.

Unlike C++, Rust can be learned. I maintain that nobody truly knows C++. There will be always C++ code that cannot be explained by an expert. Everyone learns a dialect of C++ that they feel comfortable with, but the entire space of what's possible within C++ and the implications of each feature at compile-time and run-time became too complex to be learned.
