Is C++ the Top Choice at Google?

A lot of greenfield projects in Google and new projects end up using Go or things that don't need the max performance. When you start thinking of max performance, it's still, nope, C++,. I know we are occasionally looking at other languages like Rust and whatnot. So if you regularly scope out and look at different languages, but currently C ++ is what you'll get when you say I need to get performance out of my machines.
