Artificial intelligence will replace some people in their jobs, based on the "five-second rule", Kai-Fu Lee predicted that about 90 percent of jobs such as translators, journalists, assistants, security guards, sales, customer service, trading, accountants, drivers, housekeepers and other jobs will be fully or partially replaced by AI in the next 10 years. At the same time, he also believes that most jobs will be transformed into new forms of work.

In the stock trading market, ordinary traders act as intermediaries, completing trading operations and entering information according to the instructions of buyers or sellers. For a transaction can be closed, they only need to focus on specific figures and market conditions to make a judgment, basically each independent judgment to spend two or three seconds to make, today's automation technology and artificial intelligence technology is sufficient to complete this kind of simple, intermediary nature of the work. As a result, traditional traders are giving way dramatically to computers in major stock exchanges today.

When driving a car, the human driver makes judgments based on road conditions that the human brain can process in a short period of time and respond to immediately. Car driving this work needs to quickly perceive the external environment, rapid judgment and response ability, artificial intelligence can do faster and more accurate, so Li Kaifu believes that the car driving work will eventually be fully replaced by automatic driving technology, which will also make driving safety to enhance a level.

Some jobs can be replaced even if the decision-making process is more than five seconds for a human being, such as a doctor's diagnosis based on a patient's lab results, which a doctor can't complete in a few seconds, but computer vision technology and AI medical technology can do. Lee Kaifu said that in the future, artificial intelligence can replace part of the doctor's work, quickly complete the initial screening of the condition based on data or images.

A rough estimate of all human jobs, Lee predicted that about 50 percent of human jobs will be affected by AI. So how should people who are currently in these easily replaceable industries respond? "Think to the depth, think across fields, and know what the limitations of AI are." Lee Kai-Fu said that AI is a system of objective judgment based on big data in a single field, so what people have to do is to think more y in the direction of strategic, cross-field.

But AI is created by humans and will not become a hegemon.
