Although the inner loops are always numerical operations, even so, the
arrangment of numbers in appropriate ways, and the appropriated ordering
of numerical operations, requires lots of non-numerical data structures,
which are not simply arrays. So calling AI "number crunching" doesn't
tell very much of the story. You could just as well call it "tree
traversing" for example... equally incompletely...

Although we are using C++ (gcc on linux) for our own work, it's easy for
me to see how another choice would be reasonable.
The choice of language for a project is a choice of a lot of different
and hard to meaningfully talk about in such general terms.
For direct source-code self-modification, there's a decent argument for LISP
as opposed to C++, as the program language semantics is more easily
Our choice of C++ is because we are valuing performance above all for this
of our system, because we've realized that thorough experimentation with
the system requires efficiency even MORE than a finished system will. gcc
on a Linux cluster of SMP machines...
But when we get to the stage of direct source-code modification (probably a
years at the present rate) we might re-code in LISP, or now, who knows.
Even though we made an error by choosing Java at Webmind inc., I still
that prog. lang. choice is among the least of the issues confronting would
AI developers. It's the mind design that's the obstacle, believe me.... I
think I have
a good one now but it's taken many years, and it's not simple enough for my
we're proceeding with it until/unless something better comes along.
