A Thousand Brains

Summary

In A Thousand Brains, Jeff Hawkins proposes a revolutionary framework for understanding human intelligence based on the Thousand Brains Theory. He argues that the neocortex does not process information in a simple hierarchy, but instead uses hundreds of thousands of cortical columns to create complex models of the world via reference frames. By learning through movement, these columns act as independent modeling engines that vote to reach a consensus on what we perceive. Hawkins further explores the future of AI, suggesting that true machine intelligence must adopt these brain-based principles rather than current "deep learning" methods. Finally, he examines the existential risks facing humanity, highlighting the conflict between our primitive old brain and the more advanced neocortex. He concludes that our legacy should shift from preserving biological genes to safeguarding and spreading human knowledge throughout the cosmos
