Maybe, but I wouldn't go back to Python 2 without async. It has also improved over time in Python. I have also had success using async in Python. I do understand what the article talks about however. Understanding the difference between blocking and non-blocking code is also a concept relevant to Python. In Node it's one of the concepts you are first introduced to, because Node is single threaded by default. I also understand in Go and other languages there are different options.

I will agree with what some is said a above, BEAM is pretty great. I have been using it recently through Elixir.
