Is that all humans are? When clockwork was the frontier, people thought the brain was akin to clockwork (which is why the mechanical turk fooled people). By analogy, now that classifiers are the frontier, we think the brain is a classifier. Our model of the mind is whatever the most complex artifact of our era is .
Just to be clear: I do think the brain classifies. But I wonder if it does other operations as well that we don't fully understand.
