I think that's a bit pessimistic.

It's not normally a good idea to rewrite applications. But new
applications could be written in a language like D or Go (obviously).
Any successful language will need to interface well with C.

The link says:
"So the go compiler compiles 120KLOC in 9.23 seconds. I got curious so I
just tested dmd against Phobos (88KLOC). That takes 1.24 seconds on my
Phobos is D's standard library, and includes templates quite a bit.

It doesn't use includes per say, but compiler-generated .di files. C++
parsing is slow anyway because of templates.
(I think both D and Go have ways to speed up compilation further).
