<p dir="ltr">This presentation was given at the VIII Conferencia Interuniversitaria “Ética y Transformación Educativa en la Era de la Inteligencia Artificial”, A Coruña, 31 October 2025. The presentation, entitled <i>¿Necesita el pensamiento crítico de la Inteligencia Artificial?</i>, explores the redefinition of critical thinking in a technological age where cognition is increasingly externalized through artificial intelligence. Drawing on Michel Serres’s <i>Pulgarcita</i> (2013) and Bernard Stiegler’s <i>La técnica y el tiempo</i> (2002), it frames AI as both an extension and a disruption of human thought—a technical prosthesis that co-constitutes our critical capacities. From this anthropological and educational perspective, the talk examines how AI transforms academic integrity: plagiarism evolves from mechanical copying to cognitive delegation. Through the 2023 Göteborg court case in Sweden, it is shown that ethical responsibility now extends beyond the individual to institutional frameworks. The Swedish experience, including the <i>Stockholm University Handbook on Preventing Plagiarism</i> (Bendixen et al., 2024), offers a pragmatic model based on AI literacy, transparency, and process-oriented assessment. Finally, the presentation argues for a preventive and participatory ethics of education—one that reinvents critical thinking not against AI, but <i>with and through it</i>, fostering co-responsibility, metacognitive awareness, and ecological reflection in academic practice.</p>
