Every single AAA studio uses C++ to write the smallest portion of their game they can in C++.
Then they put a sane, modern language on top of it many places, Actionscript at EA, Python at many other places, LUA at others, C# at others, and write in a high level language that doesn't leak abstractions like a nut milk bag.
There's a reason why every single AAA studio uses C++ for their engines and titles. And that's the same reason why it is terrible for social media applications.
