Is AI Good or Evil The Google AlphaGo has beaten the world’s best player 3-0 in ancient Chinese board game Go. It symbolizes the arrival of groundbreaking new form of Artificial Intelligence. But this soon aroused people’s concern of being replaced by AI in a majority of professions in the near future.The following paragraphs will reflect on some human-friendly AI technologies, while trying to figure out what specific hazards might happen on humans. It is undeniable that intelligent machines are helping to alleviate people’s workload. At home, there are all kinds of machines doing house chores, including washing clothes, sweeping, or cooking. It has liberated millions of women from repetitive and mundane labors so that they are allowed to apply their knowledge in the job market. In the workplace, thanks to the inventions of robots, employees can turn their attention to more creative work, such as art designing, filmmaking and writing. Laborers are free from working in workshops with poor environment, suffering from extreme temperature and polluted air. Thanks to AI machines as tools, there are fewer people enslaved by unfavorable monotonous works. In addition, since AI are capable of simulating loads of situations, we can deploy it in areas of medicine and fashion. However, there are negative consequences brought by technologies. AI technologies directly lead to an upward trend of unemployment. Professions like restaurant servers, journalists, drivers have already been taken up by computers in some developed countries. Unskilled workers aged over 50 who are unlikely to adapt to the fast pace of technology will be obsoleted by automation. Besides the disadvantaged group, people using AI technologies also another ethical issue. Since there are no global conventions on the constrains of robots invention, it is hard to prevent some crimes exploiting AI functions to hacking into people’s private computers. It is even feared that one day when robots are smarter than human beings, they will rebels against human creators. In another word, what makes people feel insecure is the unpredictable disobeying of robots. My own view is that the benefits brought by AI machines outweighs the drawbacks. Despite that people are lacking the confidence of coping with potential threats imposes by robots, many more new technologies are invented to improve our work efficiency. Up until now, AI has been applied to very limited fields with few scope for the system to do much damage.
