That is the real problem. Any sufficiently popular language will inevitably be used in scenarios it is not suited for. Python has now reached that threshold, so all sorts of communities are trying to stretch it and pull it every other way. Sometimes this makes the language better, sometimes it's just a source of complication and frustration.

There is also the issue that some quarters feel python's role is being eroded by newer stuff like golang and nodejs, which were built with high-performance multithreading in mind from the start. I personally think this is not much of a concern (if you are willing to trade python for golang or nodejs, you were not really using python because of its expressiveness and conciseness in the first place), but clearly a lot of people do.
