OP was needlessly combative. But, if I have to write a program that is correct (i.e. does what I want it do to), I'm going to write it in Rust. Not because you cannot write correct programs in Python. But because it's easier to prove it's correct in Rust.
As a solo dev, I find that I start off in Python, but at a certain project size I find it too unwieldy to manage (i.e. make changes without breaking things) and that's when I implement part or all of the project in Rust.
