A Thousand Brains: A New Theory of Intelligence, by Jeff Hawkins.
Jeff Hawkins, a neuroscientist and computer engineer, claims that answering questions about the brain is difficult because our fundamental understanding of how the brain works is incorrect. Hawkins adopts a radical new approach to the brain in A Thousand Brains, with startling ramifications. Hawkins proposes that your brain is arranged into thousands upon thousands of independently computing units called cortical columns, which he calls the Thousand Brains Theory of Intelligence. Each of these columns processes input from the outside world in the same manner, and each constructs a full picture of the world. Because each column's connections to the rest of the body varies, each has its own frame of reference. By voting on all of the models, your brain sorts them out. The brain's primary task is to organise the hundreds of distinct ideas it possesses at any one time, rather than to construct a single thinking. It's also a lot simpler to build one yourself if you understand how the brain works. Hawkins is an engineer first and foremost, and A Thousand Brains explains how a new understanding of intelligence may lead to really intelligent artificial intelligence. Hawkins looks at how we may build computers that can learn on their own, why we shouldn't be afraid of superintelligent systems, and how human and machine intelligence might mix in the future.
