> So for how long will the python community pretend that performance isn't a problem?
Which python community are you talking about? Cython, numba, numpy, pypy?
> The stories about teams that were able to go down from N servers to 1 server by switching from Python to Go/Scala/node.js will hurt it in the long run.
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.
