Native languages for web development

Why are "native" languages* almost never used for web development? Shouldn't FastCGI be just as good as what web servers do with Perl or PHP? What am I missing?

* languages designed for AOT compilation to opcodes like C++, Ada, C, D, Pascal, or Go

I think the reason that statically typed languages are not used in programming is you have to know the types at compile time, and since its not possible to predict what kind types you will recieve till runtime, a program wont run without a lot of parsing that wouldnt have to be done with a dynamically typed language. This is the problem with Dart, it has fake static typing, so it is really not simplifying anything.
