The post seems a bit undercooked for my liking. Isn't there a library from Guido called Tulip for doing Async tasks?

That said, reaching "true" concurrency in Python will always be impossible no matter how you twist the language or monkey patch it. But one has to also decide on the trade of. I've personally used Celery in almost all my tasks, and even though it is bit over-loaded with features, you can always trim it down to your use, and it works pretty damn smoothly. There is a talk by Instagram developer Rick Branson regarding the usage of Celery in Instagram. I would suggest people to check it out.

I'm also surprised that there wasn't a mention of Erlang, which is being predominantly used by Facebook chat, and Haskel or Clojure, which would allow us to achieve concurrent programming without breaking a sweat. Surely, one doesn't have to be a grey beard wizard to learn any one of these three languages?

Good luck to the him, though. Go seems like a very exciting language, whenever I've used to it. Sometimes, it doesn't even seem like a new programming language, just a weird concoction of Java, C++ and Python.
