You may have a house robot that can do housework for you. But is it so smart? Laura, a robot in the National Library in Spain, is copying the old books and writings in its collection. Aurora, a headless dog-sized robot, used to keep birds and other animals away at an Alaskan airport. Ever R 6, another 1.8-metre-tall legless robot, is waving its arms to guide musicians through a performance.
Those robots above require artificial intelligence. AI is a computer system that can understand languages, make decisions and solve problems. Humans can teach AI skills by using a process called machine learning. Humans give AI information such as books, photos or videos to train it. The more information it studies, the better it can do its job.
▲ . For example, when you watch TV, AI is watching you. It'll know what your favourite is and suggest similar ones. In hospitals, AI is very good at suggesting treatments and can even invent new medicines. To cut down food waste, some schools introduce online systems for the students to choose meals ahead of time. In cities, AI is used to watch out for cars that make black smoke. It works together with the police and transportation teams to stop them and keep the air clean. AI can help us fight climate change by finding clever ways to reduce energy use.
Some people worry that AI will take away a large number of jobs and also fear that AI could develop out of our control and bring danger to humans. However, humans expect AI to help achieve more in less time. It is believed that the flying car will be made to offer an easier way out of the morning traffic jam. Humans imagine AI might even find a way to solve the problems of our energy needs completely. Anyway, there is still a long journey for humans and AI.
