In recent years I’ve grown skeptical of the claimed benefits of CS; they seem easily outweighted by its harms. I have shifted by attention to social and ethical issues connected to technology, especially the climate crisis and the problem of mass surveillance. Corresondingly, I have shifted most of my university teaching to ethics (course ecs188). I support social justice and environmental movements including BDS, BLM, and XR. I anticipate retiring from UCD in 2023. I am getting old (currently 59), and my views—and the surrounding culture—have evolved to a place where I am quite the outsider.
