Alan Cooper's UX Australia 2018 closing keynote argues that while most people agree technology products should not be evil, far fewer know how to deliver on that responsibly. He presents provocative results from recent work on responsible innovation, framed as an "Oppenheimer moment" for practitioners who realize well-intended products can be used in harmful ways. The talk challenges designers to examine assumptions, consider long-term externalities, and act as good ancestors when shaping technology.
