This volume offers an in-depth analysis of the metaverse and its implications with other, more advanced technologies through an interdisciplinary approach that bridges the social sciences with the hard sciences. The interaction among the latest technologies emerges as a pivotal element of contemporary transformation, marking the transition to a new era in which the boundary between the real and the digital becomes increasingly blurred while the physical dimension progressively yields space to the immaterial. This scenario raises issues of great theoretical and practical significance, prompting questions about the future of human interactions, economic dynamics, and governance models. The contributions gathered in this volume explore the critical implications and challenges that arise across different fields of knowledge, offering a nuanced reflection on the relationship between law, economics, and technological innovation. Through a multiplicity of perspectives, the text outlines the contours of a constantly evolving digital ecosystem with profound repercussions for society, ethics, and institutions.
