Ray Kurzweil, The Singularity is Near: When Humans Transcend Biology

Centuries ago people didn't think that the world was changing at all. Their grandparents had the same lives that they did, and they expected their grandchildren would do the same, and that expectation was largely fulfilled.

Today it's an axiom that life is changing and that technology is affecting the nature of society. What's not fully understood is that the pace of change is itself accelerating, and the last 20 years are not a good guide to the next 20 years. We're doubling the paradigm shift rate, the rate of progress, every decade.

The whole 20th century was like 25 years of change at today's rate of change. In the next 25 years we'll make four times the progress you saw in the 20th century. And we'll make 20,000 years of progress in the 21st century, which is almost a thousand times more technical change than we saw in the 20th century.
