>how much would a company of Instagram's scale switching from Python to a lower level language like C++ I guess one thing you have to consider is 1. How many engineers do you have to hire to make Python "fast enough" vs 2. What does it cost to deploy a full C++ team? Is it easier for new programmers to learn & write safe C++ code vs. Python. I wonder what is cheaper?
