Moore's Law

Moore's law: the # of transistors that can be placed on an integrated circuit is increasing exponentially.
--More transistors can be placed on a chip, but as the # of them on the chip increases, the chance of defects ALSO increases.
--rate of increase in hard drive is similar to that of transistors
--this trend is expected to continue for the next few years (as of 2001)
--Moore stated that this law cannot be sustained indefinitely
--Wirth's law: "Software gets slower faster than hardware gets faster".
--exponential processor transistor growth does NOT equal exponential processing speed growth

I definitely agree with Moore's statement that this kind of growth cannot continue forever. The article mentioned that with this kind of growth, the size of transistors will approach that of atoms. There's only so far we can go at that point. Depending on how fast we get there, in my opinion, will affect how long this pattern occurs.
