Thanks for your feedback. We'll correct that thing about Python as soon as possible. However please agree with me that with an educational background of C/C++, learning Go was easier than learning Python.
Its concurrency is awful, and makes shooting oneselves in a foot easy. Effective go teaching you how to basically make mutex using channels is just a practical joke, right?
As for C++ and libraries - Boost was and is a big one. Want HTTP? There's a full server implementation you can reuse easily https://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/ex...
I have the same opinion on Go - it's awful, it fails to deliver its promises, but it became popular because it was "a google thing".
Google itself supports go internally, but it is nowhere near being ubiquitous or even recommended - I think that tells you something about it too.
