Description: Christof Koch argues that the cerebellum, home to 80% of the brain's neurons, contributes nothing to consciousness. According to integrated information theory, current AI systems and the cerebellum share the same problem: many neurons or parameters, but an architecture unsuited for consciousness.

Description from the channel

80% of your brain's neurons have nothing to do with consciousness. And that's exactly why current AI can't be conscious either. Dr. Christof Koch makes one of the most counterintuitive arguments in modern neuroscience: the cerebellum, which houses 80% of all your brain's neurons, appears to contribute nothing to conscious experience. Damage it and you'll lose coordination, balance, fine motor control. But you won't lose consciousness. According to integrated information theory, current AI and the cerebellum share the same fundamental problem: lots of neurons or parameters, wrong architecture for consciousness. Full conversation with Dr. Christof Koch, former president of the Allen Institute for Brain Science, on Eye on A.I.
