Ars Electronica 2023 is dedicated to the complex questions of truth and the concept of ownership in this digital age. In doing so, the festival navigates the central questions of our time. The focus is on how our perception of "authentic" and "original" is being transformed and whether truth can be owned, and how this relates to digitalization and the rapidly developing performance of artificial intelligence. How can the achievements of a tool that is so much based on the globally collective "raw material" of knowledge and creativity be made accessible to everyone and be harnessed to the benefit of all? This comprehensive volume brings together the works of artists, scientists, developers, designers, entrepreneurs and activists from around the world and delves deep into the themes of the festival, offering insights, perspectives, and thought-provoking content that reflect on the intersection of art, technology, and society.
