Theory and Practice of Generative Artificial Intelligence Usage

This editorial summarises the special issue entitled "Theory and Practice of Generative Artificial Intelligence Usage" and briefly reflects on generative artificial intelligence-related phenomena.Generative artificial intelligence is a new technology that is not only known in professional circles but has also gained widespread recognition and popularity due to its easy accessibility and benefits for lay users.The high level of interest in this technology stems not only from current experience with it and its current usefulness, but also from the assumption that this new technology will significantly affect a wide range of industries, many types of jobs, and the everyday lives of many people in the future.That is why, in this special issue, we have focused not only on the purely technical aspects of GenAI, but also on the social and commercial aspects related, for example, to institutional innovation, as well as ethical aspects and philosophical perspectives.This special issue consists of seven articles.
