Computers vs. the human brain has been a worrisome topic, every since digital computers were being used over 60 years ago. This topic has been heavily depicted in movies like 2001 Space Odyssey, Terminator, and I, Robot. This topic raises a lot of thought-provoking ideas on the comparison of the human brain and modern computers, which has a higher "Intelligence". The link I have provided and the book also go into some detail on this question. The main thing I think that should be focused on is, what do we describe as intelligence. There are some things like according to our book that we do flawlessly and make it seem easy like depth perception, while a computer can do something that we find incredibly extraordinary like beating the world's greatest chess player in chess with relative ease. I define natural intelligence on a human beings survival IQ, because that is what our intellect was naturally created for. Small things that we find simplistic, like reading someones body language or mood, is almost impossible for a computer to comprehend. These subtle inferences our what I deem more intelligent, because they help us survive. In our current society these adaptive qualities rarely come into use. Today's intelligence has been redefined by our societies in a matter of factual recognition and number crunching. These are the categories in which computers are superior. Our invention of these so called "Electric Brains" have capabilities that aren't even fathomable with a human brain. The amount of knowledge today's computer can access in matters of seconds is extraordinarily sophisticated when compared with our brains. This though is not what I deem to be the higher intelligence. I go back to the primal nature of intelligence. The reason that we have intelligence, is for methods of survival. Our intelligence models for us a organized manner in which we can reason, think, and problem solve in seconds fact, which in turn increases our survival rates. Computers have not reached even close to the level of sophistication that our brains are at.
