Empathy evolves from user-centered usability to human-centered dignity and humanity-centered sustainability. We treat empathy as skill, process, and moral stance—supported by rigorous methods and reflexive practice that avoids “empathy theater.” The chapter frames limits and biases, then explores how AI can augment empathic reach at scale without replacing human care, emphasizing cultural sensitivity, accountability, and the embedding of equity and long-term stewardship in design criteria.
