Below: The future of the brain: Jeff Hawkins, the creator of Palm Computing and author of "On Intelligence," talks about how brain science is about to fundamentally change. Fascinating talk!

Hawkins postulates that intelligence is defined by prediction, not by behavior, as previously thought. He says we're constantly making predictions about the world, constantly having expectations about how the world is going to behave at any given moment.

Our neo-cortex, which sits on top of our "old" brain, the brain of our ancestors, memorizes everything. When the neo-cortex sees something similar to what it has seen before, it thinks, "Ahh, I know that; I've seen it before." It allows the neo-cortex to predict the future.

The future, then, of artificial intelligence, then, will be in creating machines that will also learn to predict, to anticipate, to learn from everything it "sees" and "hears" and "experiences."
