Jeff Hawkins, co-founder of Numenta and a leading figure in neuroscience, dives into the fascinating nature of intelligence. He explains how the neocortex constructs models of our world, emphasizing the brain's predictive power. The discussion covers the alignment problem in artificial intelligence, the complexities of truth and belief, and the challenges posed by superintelligent AI. Hawkins challenges listeners to rethink human cognition and the future implications of AI, offering deep insights into the evolving relationship between technology and intelligence.

Intelligence as Internal Model
Intelligence involves learning an internal model of the world within the neocortex.
This model enables recognition, action, planning, and thought.
insights INSIGHT
Unconscious Predictions
Predictions in the brain are mostly unconscious and occur within individual neurons.
These predictions are based on internal models and draw attention to errors or surprises.
insights INSIGHT
Cortical Columns and Common Algorithm
The neocortex consists of cortical columns, each acting as a processing unit with a common algorithm.
This suggests that different brain functions like vision, language, and hearing share the same underlying mechanism.

How a New Understanding of the Brain Will Lead to the Creation of Truly Intelligent Machines
Jeff Hawkins
Sandra Blakeslee
In 'On Intelligence,' Jeff Hawkins, with the help of Sandra Blakeslee, outlines his memory-prediction framework theory of the brain. This theory posits that the brain is a hierarchical, predictive system that uses memory to make continuous predictions about future events. Hawkins argues that current approaches to artificial intelligence are flawed because they do not understand the fundamental principles of how the brain works. He explains how the neocortex, the seat of intelligence, operates through a hierarchical structure, making predictions based on associative memory. The book discusses the implications of this theory for neuroscience, the development of intelligent machines, and our understanding of human behavior and cognition.
A Thousand Brains
A New Theory of Intelligence
Jeff Hawkins
In this book, Jeff Hawkins presents a revolutionary theory of intelligence that explains how the brain creates intelligence through the use of maplike structures to build tens of thousands of models of the world. The book delves into how these models enable us to perceive the world, understand our sense of self, and originate high-level thought. It also discusses the implications of this theory for machine intelligence and the future of humanity, highlighting potential threats and opportunities[1][4][5].
Sam Harris speaks with Jeff Hawkins about the nature of intelligence. They discuss how the neocortex creates models of the world, the role of prediction in sensory-motor experience, cortical columns, reference frames, thought as movement in conceptual space, the future of artificial intelligence, AI risk, the “alignment problem,” the distinction between reason and emotion, the “illusory truth effect,” bad outcomes vs existential risk, and other topics.
