The real question is: what is the driving force behind Moore's Law. If the reason for the heretofore seen doubling time is something intrinisic in the process by which the chips are made, then the time of Moore's Law may indeed be drawing to a close. There is no real controversy about the fact that there is a hard bottom to lithography -- it can't continue to quantum dimentions. However, it seems somewhat unlikely that there is a doubling time implicit in a process of manufacture. More likely, the reason that there is a reliable pattern to processor devellopment is that there is such a large industry behind it. Once you have a sufficient number of people working independantly, statistical forces insure that each new breakthrough will inevitably be made with an approximately constant rate.
