As artificial intelligence technology rapidly advances, it is likely to implement Artificial General Intelligence (AGI) and Artificial Superintelligence (ASI) in the future. The highly intelligent ASI systems could be manipulated by malicious humans or independently evolve goals misaligned with human interests, potentially leading to severe harm or even human extinction. To mitigate the risks posed by ASI, it is imperative that we implement measures to ensure its safety and controllability. This paper analyzes the intellectual characteristics of ASI, and three conditions for ASI to cause catastrophes (harmful goals, concealed intentions, and strong power), and proposes a comprehensive safety solution. The solution includes three risk prevention strategies (AI alignment, AI monitoring, and power security) to eliminate the three conditions for AI to cause catastrophes. It also includes four power balancing strategies (decentralizing AI power, decentralizing human power, restricting AI development, and enhancing human intelligence) to ensure equilibrium between AI to AI, AI to human, and human to human, building a stable and safe society with human-AI coexistence. Based on these strategies, this paper proposes 11 major categories, encompassing a total of 47 specific safety measures. For each safety measure, detailed methods are designed, and an evaluation of its benefit, cost, and resistance to implementation is conducted, providing corresponding priorities. Furthermore, to ensure effective execution of these safety measures, a governance system is proposed, encompassing international, national, and societal governance, ensuring coordinated global efforts and effective implementation of these safety measures within nations and organizations, building safe and controllable AI systems which bring benefits to humanity rather than catastrophes.
