“Something Old, Something New” – Reflections on AI and the Just War Tradition

Abstract

This chapter presents reflections and considerations regarding artificial intelligence (AI) and contemporary and future warfare. As “an evolving collection of computational techniques for solving problems,” AI holds great potential for national defense endeavors (Rubin, Stafford, Mertoguno, & Lukos, 2018). Though decades old, AI is becoming an integral instrument of war for contemporary warfighters. But there are also challenges and uncertainties. Johannsen, Solka, and Rigsby (2018), scientists who work with AI and national defense, ask, “are we moving too quickly with a technology we still don't fully understand?” Their concern is not if AI should be used, but, if research and development of it and pursuit of its usage are following a course that will reap the rewards desired. Although they have long-term optimism, they ask: “Until theory can catch up with practice, is a system whose outputs we can neither predict nor explain really all that desirable?” 1 Time (speed of development) is a factor, but so too are research and development priorities, guidelines, and strong accountability mechanisms. 2
