I work at a fairly large Python shop and we have some real performance problems with Python.
Most real world software will use many core libraries implemented in C/C++ for doing the heavy lifting. Just the FFI and creating all those Python objects makes it slow.
Python is a great language for prototyping and/or usage as a glue code.
Personally, I am more inclined to use Go for anything quick and performant. If Carbon language becomes a reality, I would bet on that since it allows seamless interoperability with C++ (and there is a large existing eco system). Else, time to learn Rust.
