python simply not scaleable enough for google?

I can't.  Too much about the language is dynamic.  The untyped variables
alone are a killer.

	int a,b,c;
	...
	a = b + c;

In C, this compiles down to just a few machine instructions.  In Python,
the values in the variables need to be examined *at run time* to determine
how to add them or if they can even be added at all.  You'll never in
a million years get that down to just two or three machine cycles.

Yes, technically, the speed of a language depends on its implementation,
but the nature of the language constrains what you can do in an
implementation.  Python the language is inherently slower than C the
language, no matter how much effort you put into the implementation.  This
is generally true for all languages without strongly typed variables.
