if there's one principle thatI'd like to have my name attached to, Lederberg's principle is that machines will becomereally smart only when 1) they can directly read the literature and 2) spend some timeliving in the real world where the survival of thefittest is what will determine who's out there. Aslong as we have to spoon-feed them datum by datum, they're going to be moving in a verycumbersome and costly way, indeed.
