Why is calling out to C code via something like numpy a bad thing?

Python is never going to be as fast as C. Ever. Even if you somehow managed to decouple numeric types from PyObject in a backwards compatible way it would not be as fast.

Type Hints can’t be used as an optimization in the interpreter due to the way they are resolved. And in any case, it would not be safe to do so and there are very few cases where optimizations make sense.
