Abstract: Rapid advances in convolutional networks and other machine learning techniques, in combination with large databases and the relentless hardware advances due to Moore’s Law, have brought us closer to the day when we will be able to have extended conversations with programmable systems, such as advanced versions of Alexa or Siri, without being able to tell their siren voices from those of humans. This raises the questions to which extent systems that can pass a non-trivial version of the Turing test will also feel anything, that is, be conscious. I shall argue against this possibility for three reasons. Firstly, intelligent behavior, including speech, is conceptually radically different from subjective experience. Secondly, clinical case studies demonstrate that the neural basis of intelligence, self-monitoring, insights and other higher-order cognitive processes in the frontal regions of neocortex are distinct from the neural correlates of conscious experience in the posterior cortex. Thirdly, Integrated Information Theory (IIT), a fundamental theory of consciousness, predicts that conventional computers, even though they will be able, at least in principle, to simulate human-level behavior, will not experience anything. Building human-level consciousness requires neuromorphic computer architectures.
This talk is free and open to the public.
