We'll see about that. As of yesterday I have started writing performance-critical software in Python. It's a large application, and many components might go slow in Python. However, my suspicion is that one part of the code will be particularly slow. I will then optimize that part by writing it as a C module. By using Python I can write the application quicker, test for correctness, and optimize the most important pieces without wasting time writing the entire thing in C.
