Artificial intelligence researchers Eliezer Yudkowsky and Nate Soares argue that the development of superhuman artificial intelligence presents existential risks to humanity. Drawing on AI alignment theory, computer science, decision theory, and long-term technological forecasting, the book examines scenarios in which advanced AI systems could act beyond human control or incompatible with human survival. The authors critique current approaches to AI development and discuss the ethical, political, and technical challenges associated with managing increasingly powerful machine intelligence
