With the rapid advances in generative artificial intelligence, interest in—and concern about—Artificial General Intelligence (AGI) and superintelligence has grown dramatically. As these technologies continue to evolve, we must begin preparing answers to several critical questions. How soon will AGI and superintelligence become a reality? If AGI does emerge, what measures will be necessary to ensure the peaceful coexistence of humans and intelligent machines? Above all, how can we detect the early signs that an AGI system may be operating beyond human oversight or control?
