Moore's law is most certainly not accelerating  in fact: 19651990 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 (1995present). http://www.physics.udel.edu/wwwusers/watson/scen103/intel.html 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 breakthrough in computing to continue to obtain performance increases over time past this point. Len.
