Love this quote from the article:
Everyone knows that modern computers are better than old ones. But it is hard to convey just how much better, for no other consumer technology has improved at anything approaching a similar pace. The standard analogy is with cars: if the car from 1971 had improved at the same rate as computer chips, then by 2015 new models would have had top speeds of about 420 million miles per hour. That is roughly two-thirds the speed of light, or fast enough to drive round the world in less than a fifth of a second.
The problems of meeting Moores Law with current technology and the impressive solutions needed ahead, to wring any more speed from computer chips.
