""We won't experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today's rate)"......... The Law of Accelerating Returns also explains exponential advancement of life (biology) on this planet. Looking at biological evolution on Earth, the first step was the emergence of DNA, which provided a digital method to record the results of evolutionary experiments. Then, the evolution of cells, tissues, organs and a multitude of species that ultimately combined rational thought with an opposable appendage (i.e., the thumb) caused a fundamental paradigm shift from biology to technology. The first technological steps — sharp edges, fire, the wheel — took tens of thousands of years. For people living in this era, there was little noticeable technological change in even a thousand years. ..... By 1000 A.D., progress was much faster and a paradigm shift required only a century or two. In the 19th century, we saw more technological change than in the nine centuries preceding it. Then in the first 20 years of the 20th century, we saw more advancement than in all of the 19th century. Now, paradigm shifts occur in only a few years' time. The World Wide Web did not exist in anything like its present form just a decade ago, and didn't exist at all two decades before that. As these exponential developments continue, we will begin to unlock unfathomably productive capabilities and begin to understand how to solve the world's most challenging problems.

There has never been a more exciting time to be alive."
