I wouldn't be so sure for Python. It's getting cluttered by the new additions, but what it's very good at is making very concise programs that, while brittle, can achieve a lot. Rust is mostly the opposite of that... I've been coding almost exclusively in Rust for the past two years and love it, but I really don't get why we should have universal tools.

Not a professional, just wrote some Python. I definitely find Rust difficult to learn. Mutability, variable borrowing, variable lifecycles etc, do I really need this? Personally I only want to learn another language rather than Python for performance issues, and C++ is far easier and a lot more intuitive.

Rust is a lot easier to learn than C++.
