Abstract
<jats:p>We live immersed in a post-digital society, where technology is no longer an external tool but the invisible foundation that shapes our reality. This book, the result of the MELISE Project and coordinated by Javier Gil Quintana (UNED), is an invitation to move from being passive spectators to active protagonists in the media ecosystem. Aimed especially at older adults, but of interest to all citizens, it addresses the fundamental challenges of our time: growing distrust of the media, the uses and abuses of generative artificial intelligence, and the critical formation of opinions in digital environments. Through a journey ranging from philosophical reflection on knowledge to practical strategies for visual verification and detecting hoaxes, the book offers a conceptual framework and concrete tools for navigating with autonomy and critical thinking. With a pedagogical and interactive approach, this volume aims to repair the digital mirror, restoring to the most vulnerable sectors the leading role they deserve in building a more just, critical, and humane society.</jats:p>
