From driving to landing on moon, more and more human tasks are being taken over by arti^cial intelligence（AI-人工智能）.It will make everyday tasks easier and bring benefits to different industries.
And yet, like any other technology, AI will also bring risks and dangers. When people mention that AI could be dangerous, they think of the situation in films where an AI program decides to kill or enslave all humans. While this possibility is unlikely for now, there are many other dangers that AI could bring to mankind.
In February 2018, a group of AI experts got together to discuss the possible misuse of AI. What they fOund was that “Every AI advance by the good guys is an advance fbr the bad guys, too”. Their main worry was that criminals could use AI for many bad purposes, including using AI to create websites that could steal people's personal information. Another possible risk was faster hacking（黑客）一AI programs could be taught to ^nd weaknesses in software and break into computer systems. Some other risks were as dramatic as the ones we see in books and movies. For example, long-distant attacks could be made easier through the use of AI. And, finally, there were some worries on imitating voices as well. It is possible that AI could be used to make false photos and videos. In china, tech giant Baidu has developed a program called Deep Voice that can “clone” anyone's voice by studying a 3.7-second audio sample （声音样本）.
Many people in the tech world have expressed worry about AI. People like US businessmen Bill Gates and Elon Musk have called for the industry to be more strictly controlled, as there are few laws currently governing the use of AI. Famous British Physicist Stephen Hawking even thought AI could finally cause the end of mankind. “Once humans develop artificial intelligence, it will take off and redesign itself at an alarming rate. Humans...couldn't compete and would be replaced.”
