Anil Seth
The neuroscientist who argues that consciousness is a controlled hallucination of the living body—and whose careful, experimental science of mind is the clearest available argument that intelligence and experience are different things, that machines can accumulate indefinitely on one while remaining permanently empty of the other.
Anil Seth is the scientist of the felt world. He arrived at the study of consciousness by way of machines—degrees in natural sciences, knowledge-based systems, and computer science and artificial intelligence before he became a neuroscientist at Sussex—and the route matters, because his eventual skepticism about machine consciousness is the conclusion of someone who knows the computational territory from the inside. His central conviction is that consciousness is a biological phenomenon as natural and tractable as life or digestion, and that it can be studied without first solving every metaphysical puzzle about it. The brain, on his account, is a
prediction machine, forever generating its best guess about a world it never directly touches; our experience of that world, vivid and seamless as it feels, is a
controlled hallucination kept honest by sensory error. From this reorientation he draws a conclusion the AI industry would rather not hear: that
