4、is probably related to the mans parking number “A 1214”？A. The mans birthday.第1页，共11页Hollywoods theory that machines with evil （邪恶）minds will drive armies of killer robots isjust silly. The real problem relates to the possibility that artificial intelligence（AI） may bee extremely good at achieving s
5、omething other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics （控制论），put it this way: If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere （干预），we had better be quite sure that t
6、he purpose put into the machine is第6页，共11页the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence.

There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed
11、 out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams-yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off as if super intelligent machines are too stupid to think of t
12、hat possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, Anyone who expects a source of power in the transformation of these atoms is talking moonshine.However, on September 12, 1933, physicist

17、you pack on the pounds or keep them off. 36 Here are some ways to turn your home into part of your diet plan.37 Dark environments are more likely to encourage overeating, for people are often less self-conscious when they9re in poorly lit places-and so more likely to eat lots of food.
