Ray Kurzweil - How to Create a Mind - The Secret of Human Thought Revealed

“This book is a Rosetta stone for the mystery of human thought. Even more remarkably, it is a blueprint for creating artificial consciousness that is as persuasive and emotional as our own. Kurzweil deals with the subject of consciousness better than anyone from Blackmore to Dennett. His persuasive thought experiment is of Einstein quality: It forces recognition of the truth.”

—Martine Rothblatt, chairman and CEO, United Therapeutics; creator of Sirius XM Satellite Radio

“Kurzweil’s book is a shining example of his prodigious ability to synthesize ideas from disparate domains and explain them to readers in simple, elegant language. Just as Chanute’s Progress in Flying Machines ushered in the era of aviation over a century ago, this book is the harbinger of the coming revolution in artificial intelligence that will fulfill Kurzweil’s own prophecies about it.”

—Dileep George, AI scientist; pioneer of hierarchical models of the neocortex; cofounder of Numenta and Vicarious Systems

“Ray Kurzweil’s understanding of the brain and artificial intelligence will dramatically impact every aspect of our lives, every industry on Earth, and how we think about our future. If you care about any of these, read this book!”

—Peter H. Diamandis, chairman and CEO, X PRIZE; executive chairman, Singularity University; author of the New York Times bestseller Abundance: The Future Is Better Than You Think

As the most important phenomenon in the universe, intelligence is capable of transcending natural limitations, and of transforming the world in its own image. In human hands, our intelligence has enabled us to overcome the restrictions of our biological heritage and to change ourselves in the process. We are the only species that does this.

The story of human intelligence starts with a universe that is capable of encoding information. This was the enabling factor that allowed evolution to take place. How the universe got to be this way is itself an interesting story. The standard model of physics has dozens of constants that need to be precisely what they are, or atoms would not have been possible, and there would have been no stars, no planets, no brains, and no books on brains. That the laws of physics are so precisely tuned to have allowed the evolution of information appears to be incredibly unlikely. Yet by the anthropic principle, we would not be talking about it if it were not the case. Where some people see a divine hand, others see a multiverse spawning an evolution of universes with the boring (non-information-bearing) ones dying out. But regardless of how our universe got to be the way it is, we can start our story with a world based on information.

The story of evolution unfolds with increasing levels of abstraction. Atoms—especially carbon atoms, which can create rich information structures by linking in four different directions—formed increasingly complex molecules. As a result, physics gave rise to chemistry.

A billion years later, a complex molecule called DNA evolved, which could precisely encode lengthy strings of information and generate organisms described by these “programs.” As a result, chemistry gave rise to biology.

At an increasingly rapid rate, organisms evolved communication and decision networks called nervous systems, which could coordinate the increasingly complex parts of their bodies as well as the behaviors that facilitated their survival. The neurons making up nervous systems aggregated into brains capable of increasingly intelligent behaviors. In this way, biology gave rise to neurology, as brains were now the cutting edge of storing and manipulating information. Thus we went from atoms to molecules to DNA to brains. The next step was uniquely human.
