Abstract
With this essay I want to rejoin a discussion in which I first participated ten years ago, on the question of non-human — particularly machine — agency. My renewed interest in questions of agency is inspired by developments over the last decade both in the area of interactive computing and in the debate over agency within social studies of science and technology. What I propose to do is another attempt at working these two projects together, in what I hope will be a new and useful way. The newness is not so much a radical shift in how we construct human-machine boundaries, as a reconsideration of those boundaries based in critical reflection on my own previous position, in light of what has happened since. What follows is the beginnings of the argument.
