There are significant classes of problems which *are* compute bound, and
as computers are applied more and more to planning and design problems
it seems likely that kind of application will become more significant.

In twenty years time our laptops will probably be continually optimizing
aspects of our lives using advanced linear algebra algorithms over
matrices with hundreds or thousands of millions of elements. I wouldn't
like Python to be excluded from solving such problems, and others we
currently fail to foresee.

Though my own interest does tend to lie in the areas where interaction
of various kinds dominates the need for large chunks of processing
power, I can't ignore the obvious. Many compute-bound problems do exist,
and they are important.
