My thoughts on AI AlphaGo won again in today’s match against Lee Se-Dol. Many people are worried that the AI will dominate the world one day. But I don’t think this could happen. On the contrary, I believe that if properly used, AI can help us in many ways. Google’s self-driving car is a good example to show how AI can help people’s daily life. We human beings have to take a lot of time to learn how to drive. For example, in Victoria, Australia, people who are new to drive need to pass the Lerner’s Permit Test first, and then practice no less than 120 hours before they are permitted to go solo. This is a huge time waste. By contrast, if people use Google’s self-driving cars instead, they can use this time to do more meaningful things. Furthermore, Google’s self-driving car can tremendously increase the road safety. Firstly, it is reinforced by multiple radars and sensors, which ensures it doesn’t have blind area. The processors used to handle sensor signals are also much faster than human brains, and can make responses instantaneously. Secondly, it can effectively learn from dangerous situations through the network. The reason why human beings need to spend time to practice driving is because we need to get familiar with different complex situations and accumulate our experience. However, it is difficult for us to share these experience to each other. One usually can only handle situations that he or she has met before. When the situations become unfamiliar, people will be panic, leading to traffic accidents. By contrast, Google’s self-driving car are interconnected through the Internet. Data that is collected by one car can be shared to all the other cars. If everyone on earth were using Google’s self-driving car, then it could accumulate thousands of millions of hours of driving experience in a single day.
