Python is the language which has (what in business terms is coined as) the
right of first refusal.

ie. evaluate something whether it really makes sense in python, and if not
in python then start exploring what else.

The primary reasons which may encourage me to use a language other than
python are :

a. Need for raw CPU power. Yes there are a few of such use cases. When
purely CPU driven and when you really really need the CPU badly (which is
probably less than 5% cases) python performance is really poor.
b. Need for high amounts of multithreading even while being largely CPU
bound.

Yes - both situations can be handled by escaping to C from python, but I
would much rather handle these in Java (or languages based on JVM) rather
than C unless I am in a very constrained hardware situation.

On a separate note I do believe as we start heading towards the 32 core
situation (say in 5 yrs time) - there better exist a better solution than
the GIL :)
