The computer in your cell phone today is a million times cheaper and a thousand times more powerful and about a hundred thousand times smaller (than the one computer at MIT in 1965) and so that’s a billion-fold increase in capability per dollar or per euro that we’ve actually seen in the last 40 years.

The rate is actually speeding up a little bit, so we will see another billion-fold increase in the next 25 years–and another hundred-thousand-fold shrinking. So what used to fit in a building now fits in your pocket, what fits in your pocket now will fit inside a blood cell in 25 years.
