To investigate the ethical implications of AI, this study will first explain what Artificial Intelligence is, how it works, and how it is different from other technologies. The second section will investigate the ethical aspects of AI, taking the UNESCO domains of education, science, culture, and communication as a starting point, as well as the global ethical dimensions of peace, cultural diversity, gender equality, and sustainability. This investigation should be seen as an exploration, not as a comprehensive analysis, ranging from cultural diversity to trust in science, from artistic creativity to critical thinking, and from AI-based decision-making to the role of AI in developing countries. The third section of this preliminary study will sketch out the central dimensions that proper ethical reflection on AI should have from the perspective of UNESCO.
