The continuous progress of information technology has really promoted the development of the Internet industry and made it prosperous today. In this process, many jobs have disappeared and many jobs have appeared. However, the number of jobs created by the Internet industry is less than the number of jobs it replaces. For example, the e-commerce industry in China is underdeveloped. The rise of e-commerce industry in China has not only replaced a large number of jobs in offline stores, but also created jobs such as couriers, customer service and engineers. It is undeniable that the number of jobs created by the e-commerce industry is less than the number of jobs it replaces. For another example, the valuation of Snapchat in 20 15 was 1500 million US dollars, but at that time the company had more than 300 employees. When Facebook bought WhatsApp, it spent $22 billion. At that time, WhatsApp had more than 50 employees. When more advanced and cheaper technology is applied to various industries, it often means that only fewer people can create the value that is equivalent to or even more than a large number of people should have created.
