Great article, I love the way Carmack communicates.

Can someone please explain how much of these performance worries is mitigated by C++11 move semantics? To me it seems like the functional style is becoming a possibility when one doesn't have to worry about the penalty of copy operations.

Not that much unless you're very disciplined in how you writ your code. Anything with more than one reference to it won't be usefully moveable.

A lot. Ignore comments to the contrary.

I'd like to hear more, please?
