What interesting times we live in. As computer scientists, we are at the centre of addressing some of modern society’s biggest challenges. Technological advances are fundamentally changing all aspects of our society. Computer science work is now much more than just code and algorithms and proofs (if it ever was) and we can acknowledge the critical importance of initiatives such as responsible research and innovation, human-centred AI, ethics in AI, digital humanism and so on. But to what extent are we outsourcing our own responsibility to these initiatives? Responsibility matters at all levels, from policies and guidelines, right down to the practical matters of what we do, who we work with, and how we work together. In this talk I propose three challenges (at conceptual, relational and personal levels) as examples of what these practical matters might entail and how we might equip ourselves to do better at putting responsible computing into practice.
