AI is evolving into a mysterious new form of intelligence — powerful yet flawed, capable of remarkable feats but still far from human-like reasoning and efficiency. To truly understand it and unlock its potential, we need a new science of intelligence that combines neuroscience, AI and physics, says neuroscientist and Stanford professor Surya Ganguli. He shares a vision for a future where this interdisciplinary approach helps us create AI that mimics human cognition, while at the same time offering new ways to understand and augment our own brains.
