Hello-oo-o? http://pobox.com/~sentience/AI_design.temp.html?

Not really - there's a lot of complexity that's unnecessary, but can't be evolved away because there's no gradual path from the local optimum to the global optimum. Like the blind spot on the retina, sort of. Or the relative complexity of an Interim Goal System, compared to a human limbic system and the complex, photon-like(*) emotion-and-worldmodel event-loop.

(*) Photon - magnetic field gives rise to electrical field, electrical field gives rise to magnetic field...
