In the modern world, the development of technology has a significant impact on various areas of human functioning. However, the appearance of the COVID-19 coronavirus pandemic and the need to implement numerous restrictions resulted in an even greater increase in the importance of new technologies, especially in such sectors as education, administration, or finance. In Poland, the introduction of the remote work system encountered many difficulties related to the unpreparedness of previous structures to implement such solutions. An example of a country where they operate efficiently, responding to the problems that Poland faces today, is Estonia, in which, beginning from 2004, the state administration sector has been gradually replaced by a digital system based on Blockchain technology. At present, in Poland, appropriate steps are already taken by the Ministry of Digitization to digitize public administration in the form of a plan of four streams. Given the protracted pandemic, the possibilities for immediate solutions and considering the advantages and disadvantages of digitizing the state seem worth attention.

The article aims to explain the importance of 5G technology in pursuing power and shaping the international competition between two superpowers: the USA and China. Accordingly, the research focus of this article is to explain how and why 5G technology is being used by China and the U.S. as a key instrument in their growing geopolitical rivalry. The study is framed within the theoretical approach of offensive realism. It is based on the primary assumption that superpowers like China and the United States tend to increase their power not only by expanding their armed forces and territorial conquests but also by using every possible opportunity to do so. The article researches two questions. What is the importance of 5G technology in the rivalry between China and the U.S.? How has the development of communication technologies influenced countries and their ability to shape the international environment? 5G technology is considered more than just the next generation of wireless connectivity, as it goes beyond traditional forms of use and addresses a new category of users. It is a structure intended to facilitate a new category of goods and services: smart cities, autonomous vehicles, automated factories, digital services, and robotization of decision-making processes.
