Computing can be a wondrous, powerful tool, bringing us information, experiences, and connections that transform our lives for the better. However, as many of us have learned, computing has also contributed to great injustices, increasing surveillance of our most vulnerable populations, eroding the middle class through economic displacement, and amplifying historical injustices embedded in society. In this talk, I discuss our responsibility as scholars to engage both the powers and perils of computing in our research, teaching, and service. I specifically focus on three sources of injustice that are missing from computing literacy: the limits of computing, the limits of data, and the responsibility of computing professionals to center these limits in their work. Throughout, I highlight recent discoveries from my lab as examples for how to engage these topics through research, and end with ideas for how the audience can engage in their own research, teaching, and service.
