Artificial intelligence (AI) is rapidly permeating many facets of our lives, raising both hope and concern about possibilities for our future. AI is transforming domains as disparate as science, medicine, commerce, government, law, the military, and the arts, and in doing so, it is forcing us to grapple with practical, political, and philosophical questions about humans and the nature of human interaction. The Harvard Radcliffe Institute Science Symposium, featuring speakers from disparate disciplines and industries, will examine AI, its impact, and its ethics by exploring current and potential applications of AI in a range of fields of inquiry, practice, and public policy.
