The technological development process of mankind in modern times is different from that of ancient times. The development of ancient technologies is only incidental events, such as gunpowder, compasses, etc., although they have had a major impact in military history, due to the simple structure, there has been no major improvement in the subsequent. This is not the case in modern technology. From the layout of the engine to the steam engine, and then to the internal combustion engine, the electric motor, the technological progress is continuous, and it is also a linear process that can be expected. Therefore, it can aim at the future and make an advanced leap in the process, such as Qian Xuesen in the case of China's very weak basic industry, It advocates focusing on the development of missiles instead of aircraft; the United States directly launched the Apollo moon landing program when artificial earth satellites and manned spaceflight lag behind the Soviet Union. These are typical manifestations of leapfrog development.
