Jeff Hawkins, the high-tech success story behind PalmPilots and the Redwood Neuroscience Institute, does a lot of thinking about thinking. In On Intelligence Hawkins juxtaposes his two loves--computers and brains--to examine the real future of artificial intelligence. In doing so, he unites two fields of study that have been moving uneasily toward one another for at least two decades. Most people think that computers are getting smarter, and that maybe someday, they'll be as smart as we humans are. But Hawkins explains why the way we build computers today won't take us down that path. He shows, using nicely accessible examples, that our brains are memory-driven systems that use our five senses and our perception of time, space, and consciousness in a way that's totally unlike the relatively simple structures of even the most complex computer chip. Readers who gobbled up Ray Kurzweil's (The Age of Spiritual Machines and Steven Johnson's Mind Wide Open will find more intriguing food for thought here. Hawkins does a good job of outlining current brain research for a general audience, and his enthusiasm for brains is surprisingly contagious. --Therese Littleton


From Publishers Weekly
Hawkins designed the technical innovations that make handheld computers like the Palm Pilot ubiquitous. But he also has a lifelong passion for the mysteries of the brain, and he's convinced that artificial intelligence theorists are misguided in focusing on the limits of computational power rather than on the nature of human thought. He "pops the hood" of the neocortex and carefully articulates a theory of consciousness and intelligence that offers radical options for future researchers. "[T]he ability to make predictions about the future... is the crux of intelligence," he argues. The predictions are based on accumulated memories, and Hawkins suggests that humanoid robotics, the attempt to build robots with humanlike bodies, will create machines that are more expensive and impractical than machines reproducing genuinely human-level processes such as complex-pattern analysis, which can be applied to speech recognition, weather analysis and smart cars. Hawkins presents his ideas, with help from New York Times science writer Blakeslee, in chatty, easy-to-grasp language that still respects the brain's technical complexity. He fully anticipates—even welcomes—the controversy he may provoke within the scientific community and admits that he might be wrong, even as he offers a checklist of potential discoveries that could prove him right. His engaging speculations are sure to win fans of authors like Steven Johnson and Daniel Dennett. Copyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.


From Booklist
A successful designer of handheld computers, Hawkins here explains (with help from New York Times science writer Blakeslee) his passion for artificial intelligence (AI). He holds that AI research has been on an unpromising path toward developing a program big and fast enough to be pronounced "intelligent." Such a brute-force approach is not how the human brain functions, so by way of proposing an alternative AI strategy, Hawkins explains how our brains work, admitting that his views are speculative. He delves into the anatomy of the neocortex, the thin structure that covers the brain and is the seat of higher-level thought. Hawkins virtually encapsulates for a popular audience the scientific literature on how the neocortex constructs a model of the world. The author becomes quite detailed in his explanations of memory formation yet never digresses from his core precept that intelligence is prediction. His argument is complex but comprehensible, and his curiosity will intrigue anyone interested in the lessons neurobiology may hold for AI. Gilbert Taylor

Review
"On Intelligence will have a big impact; everyone should read it. In the same way that Erwin Schrödinger's 1943 classic What is Life? made how molecules store genetic information then the big problem for biology, On Intelligence lays out the framework for understanding the brain."
--James D. Watson, president, Cold Spring Harbor Laboratory, and Nobel laureate in Physiology

"Brilliant and embued with startling clarity. On Intelligence is the most important book in neuroscience, psychology, and artificial intelligence in a generation."
--Malcolm Young, neurobiologist and provost, University of Newcastle

"Read this book. Burn all the others. It is original, inventive, and thoughtful, from one of the world's foremost thinkers. Jeff Hawkins will change the way the world thinks about intelligence and the prospect of intelligent machines."
-- John Doerr, partner, Kleiner Perkins Caufield & Byers



Book Description
From the inventor of the PalmPilot comes a new and compelling theory of intelligence, brain function, and the future of intelligent machines

Jeff Hawkins, the man who created the PalmPilot, Treo smart phone, and other handheld devices, has reshaped our relationship to computers. Now he stands ready to revolutionize both neuroscience and computing in one stroke, with a new understanding of intelligence itself.

Hawkins develops a powerful theory of how the human brain works, explaining why computers are not intelligent and how, based on this new theory, we can finally build intelligent machines.

The brain is not a computer, but a memory system that stores experiences in a way that reflects the true structure of the world, remembering sequences of events and their nested relationships and making predictions based on those memories. It is this memory-prediction system that forms the basis of intelligence, perception, creativity, and even consciousness.

In an engaging style that will captivate audiences from the merely curious to the professional scientist, Hawkins shows how a clear understanding of how the brain works will make it possible for us to build intelligent machines, in silicon, that will exceed our human ability in surprising ways.

Written with acclaimed science writer Sandra Blakeslee, On Intelligence promises to completely transfigure the possibilities of the technology age. It is a landmark book in its scope and clarity.

From On Intelligence:
Let me show why computing is not intelligence. Consider the task of catching a ball. Someone throws a ball to you, you see it traveling towards you, and in less than a second you snatch it out of the air. This doesn't seem too difficult-until you try to program a robot arm to do the same. As many a graduate student has found out the hard way, it seems nearly impossible. When engineers or computer scientists try to solve this problem, they first try to calculate the flight of the ball to determine where it will be when it reaches the arm. This calculation requires solving a set of equations of the type you learn in high school physics. Next, all the joints of a robotic arm have to be adjusted in concert to move the hand into the proper position. This whole operation has to be repeated multiple times, for as the ball approaches, the robot gets better information about its location and trajectory. If the robot waits to start moving until it knows exactly where the ball will land it will be too late to catch it. A computer requires millions of steps to solve the numerous mathematical equations to catch the ball. And although it's imaginable that a computer might be programmed to successfully solve this problem, the brain solves it in a different, faster, more intelligent way.

FROM OUR EDITORS

Jeff Hawkins invented the PalmPilot, but we think that his real claim to fame is that he has written a completely accessible book on intelligence. One would imagine that the father of the fastest-selling and most ubiquitous computing device ever would be eager to tout the capabilities of "smart machines." On the contrary, Hawkins insists that computers designed to replicate human behavior are doomed to fail. To explain why, he develops an intriguing theory of how the human brain relies on memory, pattern, and prediction. "We live," he writes, "by our expectations, and someday our machines will, too." A breakthrough book for the common reader.

FROM THE PUBLISHER

"On Intelligence develops a theory of how the human brain works, explaining why computers are not intelligent and how, based on this new theory, we can finally build intelligent machines. Previous attempts at replicating human intelligence - through artificial intelligence and neural networks - have not succeeded. Their mistake, Hawkins argues, was in trying to emulate human behavior without first understanding what intelligence is." In a style that will captivate audiences from the merely curious to the professional scientist, On Intelligence explains what intelligence is, how the brain works, and how this knowledge will finally make it possible for us to build intelligent machines, in silicon, that will not simply imitate but exceed our human ability in surprising ways.
