>> At the limit of our understanding, the questions "Can a machine think like a human?" and "Is a human, after all, only a particular type of machine?" are equally unanswerable, increasingly so in a world where tangible evidence for one or another is harder and harder to come by. I believe the answer to the both questions is "no." Machines cannot think like humans for a variety of reasons, including the biological basis of one and the mechanical basis of the other. Humans evolved with a tendency toward cognitive biases as well as a capacity for sudden brilliant intuitions. Humans also evolved to be unpredictable (as an evolutionary advantage), and (as cognitive science reveals) to make decisions that sometimes precede our conscious monitoring. Biology can never be mechanism. Julien La Mettrie argued for our machine status long ago in Man, a Machine. He also thought cats were machines. Pure rubbish, as any cat owner will tell you. The "we're all machines" claim reveals more about the psychology of the claimant than about anything else. Poor La Mettrie! Making a system about his not paying attention to existence. Reminds me of Laplace's dream of a super-intelligent mind that could predict all of the future by knowing all of the Newtonian facts of the present. A sadly refuted notion. Both La Mettrie and Laplace were exhibiting creepy motives. What disappointment in their lives urged them to explore such questions? Should we ask a computer?
