Sociology offers a valuable lens through which to examine the societal transformations taking place in the age of artificial intelligence. By analysing micro-, meso- and macro-social levels, sociology can shed light on how AI affects processes such as socialisation, education, training, employment, communication, leisure and work. Furthermore, the impact of AI on social sustainability is a critical concern. This paper proposes a reflexive analysis of the sociology of AI to explore its potential contributions to social sustainability in the digital age. It considers the challenges associated with accessing and promoting digital literacy for AI, both as consumers and producers. It also considers the implications for sociology as a scientific discipline, encompassing both research methodologies and the products of inquiry. Through this analysis, the paper seeks to provide insights into how the sociology of AI can contribute to a more sustainable society in the digital age, and to identify the obstacles that need to be overcome to achieve this goal.   Received: 22 May 2024 / Accepted: 22 December 2024 / Published: 11 January 2025

Cryptocurrencies represent a new form of property that exists only on the Internet. The first cryptocurrency to appear on the global market was Bitcoin, and its appearance is linked to the first financial crisis in 2008. The market capitalization of Bitcoin grew very quickly and in 2017 reached the highest capitalization in history (334 billion US dollars). Later, there was an expansion of new cryptocurrencies, of which there are currently over 1500 (e.g. Ethereum, Tether, BNB, USD Coin, etc.). The emergence of cryptocurrencies as a new concept affects the change in the perception of payments and money as a means of payment in general. The development of the global cryptocurrency market is indeed rapid and dynamic, and it is becoming an increasingly popular method of payment. Since the emergence of cryptocurrencies is not related to central banks, the need to change the classical systems and economic policies of countries is also expressed. The dynamic development of the mentioned market takes place in parallel with the development of information technologies, so there is a trend of capital outflow from classic capital markets to emerging global cryptocurrency markets. The question arises of the survival of traditional banks in the future, as more users trust cryptocurrencies. Global cryptocurrency markets are expected to expand more and more in the future. The paper will analyze the development of the global cryptocurrency market based on a sample of five of the most significant cryptocurrencies today.

The methods used for the research will be a survey as a method of quantitative research, and an interview as a method of qualitative research. The expected results of the research are to determine whether there is an impact of the of digital technologies on the usage of mobile application at catering facilities.
