On Intelligence
Jeff Hawkins
Top 10 Best Quotes
“It is the ability to make predictions about the future that is the crux of intelligence.”
“Deep Blue didn't win by being smarter than a human; it won by being millions of times faster than a human. Deep Blue had no intuition. An expert human player looks at a board position and immediately sees what areas of play are most likely to be fruitful or dangerous, whereas a computer has no innate sense of what is important and must explore many more options. Deep Blue also had no sense of the history of the game, and didn't know anything about its opponent. It played chess yet didn't understand chess, in the same way a calculator performs arithmetic bud doesn't understand mathematics.”
“The way to eliminate the harm caused by stereotypes is to teach our children to recognize false stereotypes, to be empathetic, and to be skeptical. We need to promote these critical-thinking skills in addition to instilling the best values we know. Skepticism, the heart of the scientific method, is the only way we know how to ferret out fact from fiction.”
“But intelligence is not just a matter of acting or behaving intelligently. Behavior is a manifestation of intelligence, but not the central characteristic or primary definition of being intelligent. A moment's reflection proves this: You can be intelligent just lying in the dark, thinking and understanding. Ignoring what goes on in your head and focusing instead on behavior has been a large impediment to understanding intelligence and building intelligent machines”
“When you ask yourself, What does an intelligent system do?, it is intuitively obvious to think in terms of behavior. We demonstrate human intelligence through our speech, writing, and actions, right? Yes, but only to a point. Intelligence is something that is happening in your head. Behavior is an optional ingredient. This is not intuitively obvious, but it’s not hard to understand either.”
“to take an example closer to home, consider the fact that every few years your body replaces most of the atoms that comprise you. In spite of this, you remain yourself in all the ways that matter to you. One atom is as good as any other if it’s playing the same functional role in your molecular makeup. The same story should hold for the brain: if a mad scientist were to replace each of your neurons with a functionally equivalent micromachine replica, you should come out of the procedure feeling no less your own true self than you had at the outset. By this principle, an artificial system that used the same functional architecture as an intelligent, living brain should be likewise intelligent—and not just contrivedly so, but actually, truly intelligent.”
“There is a common misconception that the human brain is the pinnacle of billions of years of evolution. This may be true if we think of the entire nervous system. However, the human neocortex itself is a relatively new structure and hasn’t been around long enough to undergo much long-term evolutionary refinement.”
“The neocortex is not like a computer, parallel or otherwise. Instead of computing answers to problems the neocortex uses stored memories to solve problems and produce behavior.”
“The brain is an organ that builds models and makes creative predictions, but its models and predictions can as easily be specious as valid. Our brains are always looking at patterns and making analogies. If correct correlations cannot be found, the brain is more than happy to accept false ones. Pseudoscience, bigotry, faith, and intolerance are often rooted in false analogy.”
“The best ideas in science are always simple, elegant, and unexpected,”
