> Today we're focusing more on expressing solutions in code that are much closer to the way that we think. Whether it's Ruby, F#, Scala, or Javascript, the tools we're using allow for more powerful solutions in far less code and complexity than C++.

If you compare the amount of code to the ease of abstraction then I'd say C++ scales much better than languages like JavaScript. It's just that C++ gets multiplied by a huge constant: http://i.imgur.com/WxU2oLy.png
