>You can't use it for anything serious that needs to scale due to the lack of concurrency and significant memory overhead.

Please actually think about what you are saying instead of just parroting off stuff you read on blogs.

Python has concurrency. Its called multiprocessing. Of course, there is startup overhead, but it achieves the same functionality. Furthermore, processes that are most commonly threaded (like fanning out network requests) are well suited to async, which has less overhead than threads.

Also, memory considerations are relevant only for embedded systems, for which you would never use Python. Memory is dirt cheap these days.
