I think the author forgets how bad other programming languages can be. I wanted to make my life easier and tried to write a specialized image processing framework in Python. It currently runs 2 to 3 times slower than my naive C++ owing to deep copies everywhere, for example in multiprocessing&#x27;s queue. I will probably need to rewrite it in C++. There is a large category of things that are easy to do in C++ but hard to do in other languages.
