This entry explores the critical intersection between Artificial Intelligence (AI) and Diversity, Equity, and Inclusion (DEI), recognizing the growing influence of AI across diverse sectors and its impact on human decision-making. Framing DEI as a shared moral responsibility to ensure no one is left behind, the chapter examines how AI technologies can both advance and hinder DEI goals. It examines how DEI considerations are, or should be, embedded in the design, deployment, and use of AI systems. It further highlights practical examples where AI supports DEI goals and addresses the challenges AI poses to equitable outcomes. Finally, it proposes strategies for aligning AI development with DEI objectives to foster fairness, representation, and innovation in an increasingly automated world.
