Which python community are you talking about? Cython, numba, numpy, pypy?

Have you followed anything that is going on or just link-bait articles? Nearly everyone that re-implements something in another language uses different paradigms during the re-implementation, because they've learned something from the original implementation. Besides, those articles normally don't discuss any of the opportunity cost of re-invention or the long-term maintenance costs. I'm not saying they can't improve those things, but until you have the TCO over a few years, it's not an accurate portrayal.
