Nicholas Humphrey, renowned Psychology Professor, debates AI consciousness in 'Sentience: The Invention of Consciousness'. Topics include qualia, blindsight in animals, and machines mimicking consciousness. Discussion on the evolution of AI consciousness, ethical implications, and boundaries of human consciousness.
Nicholas Humphrey emphasizes intentional design as crucial for AI consciousness development.
The podcast explores blind sight in monkeys and its implications for understanding consciousness in biological and artificial entities.
Deep dives
The Nature of Consciousness
The episode delves into the nature of consciousness and the debate surrounding whether artificial intelligences (AIs) can become conscious beings. The guest, Nicholas Humphrey, discusses his views on phenomenal consciousness, qualia, and the core disagreement between himself and Dan Dennett regarding whether consciousness is an illusion. Humphrey argues that phenomenal consciousness is a carefully designed aspect of nature that plays a significant role in human psychology and behavior.
Blind Sight Phenomenon
The podcast explores the concept of blind sight, referencing Humphrey's research on monkeys with damaged visual cortexes. He details how these monkeys regained functional vision through their ancient visual system, highlighting cases where individuals, including humans, can process visual information without awareness or qualia associated with traditional seeing. The discussion touches on the implications of varying sensory experiences on understanding consciousness in both biological and artificial entities.
Sentience in Machines
The episode contemplates the potential for AIs to develop sentience and consciousness. Humphrey expresses skepticism about AIs spontaneously gaining consciousness and emphasizes the need for intentional design to instill phenomenal consciousness in machines. The conversation delves into the importance of AI displaying behaviors indicating psychological understanding and introspective knowledge, suggesting that future AI development may require biomimicry and conscious engineering.
Future Perspectives on Consciousness
The podcast anticipates shifts in public discourse around consciousness and AI development in the next three to five years. Humphrey expresses pessimism about the regression in scientific discussions on sentience and consciousness in insects and machines. He highlights the importance of engineers' creative solutions in shaping future understandings of consciousness in AI, emphasizing the dependence on practical advancements over philosophical debates for progress in this field.
In this episode we return to the subject of whether AIs will become conscious, or, to use a word from the title of the latest book from our guest today, whether AIs will become sentient.
Our guest is Nicholas Humphrey, Emeritus Professor of Psychology at London School of Economics, and Bye Fellow at Darwin College, Cambridge. His latest book is “Sentience: the invention of consciousness”, and it explores the emergence and role of consciousness from a variety of perspectives.
The book draws together insights from the more than fifty years Nick has been studying the evolution of intelligence and consciousness. He was the first person to demonstrate the existence of “blindsight” after brain damage in monkeys, studied mountain gorillas with Dian Fossey in Rwanda, originated the theory of the “social function of intellect”, and has investigated the evolutionary background of religion, art, healing, death-awareness, and suicide. Among his other awards are the Martin Luther King Memorial Prize, the Pufendorf Medal, and the International Mind and Brain Prize.
The conversation starts with some reflections on the differences between the views of our guest and his long-time philosophical friend Daniel Dennett, who had died shortly before the recording took place.
