1765, the weaver Hargreaves invented the "Jenny Loom", which triggered a chain reaction of the invention of machines and technical innovation in the cotton textile industry for the first time, and started the industrial revolution.

Since then, advanced machines such as screw machine and hydraulic loom have appeared in cotton textile industry. Soon, in many industrial sectors, such as coal mining and metallurgy, there was also machine production. With the increasing output of machines, the original power such as electricity storage, water power and wind power can no longer meet the needs.

2. Steam engine

1785, Watt's improved steam engine was put into use, which provided more convenient power and quickly popularized, greatly promoting the popularization and development of the machine. Thus, human society entered the "age of steam".

Expand the healthy development of information technology;

The healthy development of science and technology must be guaranteed from three aspects: economic conditions, social environment and national policies. It should be guaranteed from the aspects of policies, regulations, organization and institutionalization, including establishing a mechanism to ensure the social operation of R&D activities, establishing a decision-making body to ensure the development of science and technology, and establishing a science and technology system adapted to the market economy.

As long as we can always keep in mind that the ultimate goal of the development of "science and technology" is to "bring happiness to mankind to the greatest extent", we can operate healthily and continuously in society. With this general direction of social development, once the development of certain technologies harms or may harm the overall happiness of society, the development and use of such technologies must be resolutely banned. On the contrary, it is conducive to or more conducive to the overall happiness of society and constantly support such technology.
