python simply not scaleable enough for google?

That's not a Python specific issue. We drop to SciPy/NumPy for certain
compute-bound tasks that operates on vectors. If that does not help,
we drop further down to Cython, C or Fortran. If that does not help,
we can use assembly. In fact, if we use SciPy linked against GotoBLAS,
a lot of compute-intensive work solving linear algebra is delegated to
hand-optimized assembly.

With Python we can stop at the level of abstraction that gives
acceptable performance. When using C, we start out at a much lower
level. The principle that premature optimization is the root of all
evil applies here: Python code that is fast enough is fast enough. It
does not matter that hand-tuned assembly will be 1000 times faster. We
can direct our optimization effort to the parts of the code that needs
it.
