Computers cannot be compared to human brains. The first reason is that the information-processing capacity of the human brain is more powerful than any computer. According to an article titled “Can a Computer Be Conscious?” in U.S. News & World Report, “It has been estimated that the information-processing capacity of even the most powerful supercomputer is equal to the nervous system of a snail—a tiny fraction of the power available to the supercomputer inside the human skull” (64). Moreover, the kinds of processing in a human brain and a computer are different, too. For example, author Steven Pinker reported that computers found it easy to remember a 25-digit number but found it hard to summarize the gist of [children's story] “Little Red Riding Hood,” and humans found it hard to remember the number but easy to summarize the story (64).
