I have seen this idea constantly popup in most discussion relating to Python and mathematical programming. Numpy being written in C justifies itself to be above criticism of Python's inefficiencies.
I sometimes am not sure if it is programming elitism or a valid argument.
If it is a valid argument, is Python should only be used as tool for proof of concept? And when there is enough traction the existing codebase should be rewritten to one of those better languages? Have you rewritten your codebase in this way and if so what was your thought process behind it?
Imagine binding typos keeping someone awake at night. It's 2022.
