We would be able to derive some clues of the brain’s computational model from comparing the information processed by brains and modern computers. Brains and modern computers deal with different kinds of information. Brains of every species from the 302-neuron C.elegans to the 100-billion-neuron H.sapiens deal with sensory information collected from species-specific multi-modal sensors. In contrast, modern computers of every kind from smartphones to supercomputers deal with symbolic information predefined by application-oriented human programmers. Consistent with the Moravec’s paradox, which is considered to be the most significant discovery in artificial intelligence, sensory information processing is extremely easy for brains but extremely hard for modern computers, whereas symbolic information processing is comparably hard for brains but extremely easy for modern computers. Even if the brain’s computational model could be as universal as the Turing Machine, they are fundamentally different models processing different kinds of information.
