Joscha Bach (LiquidAI, formerly MIT Media Lab and Harvard) lays out a computational theory of consciousness — arguing that mind is best understood as a self-organising model that a system builds of itself and its environment. He examines what it would take for a machine to be conscious, the distinction between sentience and sapience, and why current large language models are neither. A rigorous framework connecting neuroscience, cognitive science, and AI that is essential reading for anyone building at the neurotech–AI intersection.
