I mean by useless is it's so slow you can't make games or even big projects for GUI, only you can do is AI/ML, Data Science, and basic stuff. I think Rust is better because of its speed and language capabilities?
Saying one programming language is better than another is ignorant; it's like arguing a screwdriver is better than a wrench.
Each language has their strengths and weaknesses that make them better at some tasks and worse at other. Python's strength is ease of development. Performance isn’t a big concern if you just want to quickly develop the app you want.
Rust might be more performant, but if development takes twice as long and the app only runs once or a few times, that benefit is unrealized.
