Expanded:

p>The Internet has indeed created a miracle, but behind the miracle, there are increasingly prominent problems that pose great challenges to people. For example, the information gap between the rich and the poor has begun to widen, and inequality in the distribution of wealth has emerged; the openness and globalization of the network has facilitated the ****enjoyment of human knowledge and the globalization of the economy.

But it has also made network security and information security a very serious problem; the competition of the network has become the competition of high technology and talents between countries and enterprises;

The network has brought about the global circulation of information and intensified cultural penetration, and all countries are working hard to defend their own network culture. China has a long history of culture, and the question of how to make this rich culture extend on the network is particularly prominent.

In the history of technology, emerging technology refers to a series of cutting-edge technologies developed in the 21st century, and is characterized by technological convergence, in which previously disparate technologies gradually *** enjoy resources to accomplish similar tasks, such as the original voice, data, and video technologies interact with each other to create new and more efficient technologies.
