As Dr. Samuel Johnson said in a different era about ladies preaching the surprising thing about computers is not that they think less well than a man, but that they think at all. The early electronic computer did not have much going for it except a marvelous memory and some good math skills. But today the best models can be wired up to learn by experience, follow an argument, ask proper questions and write poetry and music. They can also carry on somewhat puzzling conversations.
Computers imitate life. As computers get more complex, the imitation gets better. Finally, the line between the original and the copy becomes unclear. In another 15 years or so, we will see the computer as a new form of life.
The opinion seems ridiculous because, for one thing, computers lack the drives and emotions of living creatures. But drives can be programmed into the computer’s brain just as a new form of life.
Computers match people in some roles
A. views past events as complex and having their own individuality
B. relies on a single interpretation of human behavior to explain historical events
C. interprets historical events in such a way that their specific nature is transcended
D. turns to psychological explanations in historical contexts to account for events
