Moore's Law is the mother lode of futurology, as nothing has changed the world in the last 50 years more than the exponential advancement of electronics, which is what Moore's Law is all about, and if it keeps going, nothing will change the future more. You may be wondering what is really driving this exponential trend, and you may have noticed computer clock speeds stopped going up around 2004 -- what's with that? -- and lately people have been talking about "the end of Moore's Law?" -- is it really going to end? But people have been predicting it would end for a long time, and the problems they thought would stop it got solved and didn't stop it, didn't they? Will it be different this time? Will silicon run out of steam but the exponential trend switch to a different "substrate" -- something other than silicon?
