2、lets to recharge itself. Computer viruses that no one can stop. “Predator“ fighters, which, though still controlled remotely by humans, come close to a machine that can kill autonomously.Impressed and alarmed by advances in artificial intelligence, a group of computer scientists is debating whether

3、there should be limits on research that might lead to loss of human control over computer-based systems that carry a growing share of societys workload, from waging war to chatting with customers on the phone.Their concern is that further advances could create profound social disruptions and even ha

4、ve dangerous consequences.As examples, the scientists pointed to a number of technologies as diverse as experimental medical systems that interact with patients to simulate sympathy, and computer worms and viruses that defy Iextermination/I (消灭) and could thus be said to have reached a “cockroach“ s

5、tage of ma chine intelligence.While the computer scientists agreed that we are a long way from Hal, the computer that took over the spaceship in “2001: A Space Odyssey,“ they said there was legitimate concern that technological progress would transform the work force by destroying a widening range o

6、f jobs, as well as force humans to learn to live with machines that increasingly copy human behaviors.The researchersleading computer scientists, artificial intelligence researchers and roboticists who met at the Asilomar Conference Grounds on Monterey Bay in Californiagenerally dismissed the possib

7、ility of highly centralized superintelligences and the idea that intelligence might spring spontaneously from the Internet. But they agreed that robots that can kill autonomously are either already here or will be soon.They focused particular attention on the specter that criminals could exploit art

8、ificial intelligence systems as soon as they were developed. What could a criminal do with a speech synthesis system that could disguise as a human being? What happens if artificial intelligence technology is used to mine personal information from smart phones?The researchers also discussed possible

9、 threats to human jobs, like self-driving cars, software based personal assistants and service robots in the home. Just last month, a service robot developed by Willow Garage in Silicon Valley proved it could navigate the real world.A report from the conference, which took place in private on Feb.25

10、, is to be issued later this year. Some attendees discussed the meeting for the first time with other scientists this month and in interviews.The conference was organized by the Association for the Advancement of Artificial Intelligence (A.A.A.I.), and in choosing Asilomar for the discussions, the g

11、roup purposefully evoked a Ilandmark event/I (里程碑式事件) in the history of science. In 1975, the worlds leading biologists also met at Asilomar to discuss the new ability to reshape life by swapping genetic material among organisms. Concerned about possible biohazards and ethical questions, scientists

12、had halted certain experiments. The conference led to guidelines for recombinant DNA research, enabling experimentation to continue.The meeting on the future of artificial intelligence was organized by Eric Horvitz, a Microsoft researcher who is now president of the association.Dr. Horvitz said he b

13、elieved computer scientists must respond to the notions of superintelligent machines and artificial intelligence systems run Iamok/I (横行).The idea of an “intelligence explosion“ in which smart machines would design even more intelligent machines was proposed by the mathematician I.J.Good in 1965. La

14、ter, in lectures and science fiction novels, the computer scientist Vernor Vinge popularized the notion of a moment when humans will create smarter-than-human machines, causing such rapid change that the “human era will be ended.“ He called this shift the Singularity.This vision, embraced in movies

15、and literature, is seen as plausible and unnerving by some scientists like William Joy, co-founder of Sun Microsystems. Other technologists, notably Raymond Kurzweil, have welcome the coming of ultrasmart machines, saying they will offer huge advances in life extension and wealth creation.“Something

16、 new has taken place in the past five to eight years,“ Dr. Horvitz said. “Technologists are providing almost religious visions, and their ideas are resonating in some ways with the same idea of the Rapture.“The Kurzweil version of technological utopia has captured imaginations in Silicon Valley. Thi

17、s summer an organization called the Singularity University began offering courses to prepare a “cadre“ to shape the advances and help society cope with the complications.“My sense was that sooner or later we would have to make some sort of statement or assessment, given the rising voice of the techn

18、orati and people very concerned about the rise of intelligent machines,“ Dr. Horvitz said.The A.A.A.I. report will try to assess the possibility of “the loss of human control of computer-based intelligences.“ It will also Igrapplez/I (抓住), Dr. Horvitz said, with socioeconomic, legal and ethical issu

19、es, as well as probable changes in human-computer relationships. How would it be, for example, to relate to a machine that is as intelligent as your spouse?Dr. Horvitz said the panel was looking for ways to guide research so that technology im proved society rather than moved it toward a technologic

20、al catastrophe. Some research might, for instance, be conducted in a high-security laboratory.The meeting on artificial intelligence could be vital to the future of the field. Paul Berg, who was the organizer of the 1975 Asilomar meeting and received a Nobel Prize for chemistry, in 1980, said it was

21、 important for scientific communities to engage the public before alarm and op position becomes unshakable.“If you wait too long and the sides become entrenched like with G.M.O.,“ he said, referring to genetically modified foods, “then it is very difficult. Its too complex, anti people talk right pa

22、st each other.“Toni Mitchell, a professor of artificial intelligence and machine learning at Carnegie Mellon University, said the February meeting had changed his thinking. “I am very. optimistic about the future of A.I. and thinking that Bill Joy and Ray Kurzweil were far off in their predictions,“

23、 he said. But, he added, “The meeting made me want to be more outspoken about these issues and in particular be outspoken about the vast amounts of data collected about our personal lives.“Despite his concerns, Dr. Horvitz said he was hopeful that artificial intelligence research would benefit human

24、s, and perhaps even compensate for human failings. He recently demonstrated a voice-based system that he designed to ask patients about their symptoms and to respond with sympathy. When a mother said her child was having diarrhea, the face on the screen said, “Oh no, sorry to hear that.“A physician

25、told him afterward that it was wonderful that the system responded to human emotion. “Thats a great idea,“ Dr. Horvitz said he was told. “I have no time for that.“（分数：70.00）(1).A group of scientists is debating whether there should be limits on research of _.（分数：7.00）A.robots for civil useB.military
