What interesting times we are living 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. CS work is now much more than just code and algorithms and proofs (if it ever was), as recognised by the growing 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, guidelines and conceptual discussions, right down to the practical matters of what we do, who we work with, and how we work together. This short provocation will open up discussion about what these matters of practice might entail and how we can equip ourselves to do better. Responsibility in modern society depends on us.
