Artificial intelligence (AI) is increasingly pervasive in areas of legal concern, including lethal autonomous weapons systems ("killer robots"), autonomous vehicles, medical diagnostic algorithms, criminal sentencing, predictive policing, welfare distribution, consumer manipulation, and content moderation. This seminar will provide an introduction to the field of how the law treats AI. We will consider what AI is, how the law shapes its development and regulation generally, and implications in some specific subject matter areas. Please note that we will not focus on AI as a tool of legal practice (e.g., e-discovery). Readings will include legal scholarship, scholarship from other fields, and (to a lesser extent) cases, statutes, regulations, and other materials as appropriate. No technical background is required, but you must be willing to engage with the technology. Class will be centered on robust discussion, with occasional guests, informed by the readings, response papers, and student discussion questions. Students have the option of writing a longer term paper rather than shorter response papers for an additional credit.
