The Power of Future Machines is a collection of essays by experts exploring the future impact of Artificial Intelligence (Al) in various fields of human endeavor. Building upon the dialectical and analytical framework provided in the book Artificial Intelligence and the Future of Power: 5 Battlegrounds, experts from various fields (military, geopolitics, strategic affairs, physics, policy and others) engage and describe for a wider audience the potential impact of Al. Given their specific vantage points and deriving from their areas of expertise, this anthology makes for a fascinating read. The essays discuss how Al will affect policy making, both in narrow areas of expertise as well as its effect on humanity at large. Aimed at policy makers, experts and also for a broader audience, these varied perspectives on Al add something vital to the current skewed Al discourse.
