Integrated information theory of consciousness becomes panpsychism.
Koch elegantly explains the integrated information theory of consciousness, first introduced by Giulio Tononi. Admittedly, the explanation of the calculations that give rise to the exact amounts of integrated information possessed by this or that system will be opaque to most readers. Setting that aside, the principle of reentrant connectivity as the gateway to subjective experience is supported by many theorists, even if it remains unproven. Moving from that to panpsychism is a stretch, though. There appears to be a contradiction between two points. On the one hand, he says that it is generally impossible to instantiate consciousness in a machine because it is not complex enough; even one of today’s big computers. Maybe neuromorphic hardware could get there but only if it possessed many thousands of logic gates and nodes. On the other hand, consciousness does apparently emerge at the atomic level, though not at the subatomic level. Hmm!
