That is a falicy. Moore's law is most certainly not accelerating -- in

1965-1990 Moore's law stated that the number of transistors per square
inch on integrated circuits (and therefore, the speed) doubles every 2
years. The pace has since slowed down a bit, but appears to be holding
steady at doubling every 18 months (1995-present).

However, this trend cannot continue forever. In 1997, Moore predicted we
would reach the physical limits on transistor miniaturization somewhere
around 2017. Whatever the actual date, we will need a break-through in
computing to continue to obtain performance increases over time past this
