Artificial intelligence (AI) (人工智能) is growing rapidly. We are living in a world that depends more and more on AI. AI is a group of technologies that help machines get, understand and use information to do tasks.

AI’s recent developments have got a lot of social attention. Some people have welcomed AI because it makes things possible. For example, AI will have a big influence on areas like medicine and engineering. But this attention has also produced a lot of fear. Especially, many workers are worrying that AI could make them lose their jobs.

According to a recent study, nearly five percent of jobs will disappear because of AI. In some industries, AI is already doing the work that people used to do, such as assembling (装配) cars, digging the coal and lifting goods. Self-driving cars and trucks controlled by AI will also take away the driver’s jobs in the future.

On the other hand, AI will also create many new jobs for people. More people will be needed to write programmers for AI systems (系统) and they will set up and work on them, too. Meanwhile, jobs that require feelings, excellent communication skills with people will not be replaced (取代) by AI. These includes jobs in fields like teaching, nursing and personal training.

AI is here. It is changing how people live and work in many ways. That makes AI important to watch, not to fear.
