The global scientific community is undergoing a game-changing shift from human-driven models to AI-driven autonomous discovery loops. This \"AI for Science\" (AI4S) paradigm requires a complete rewrite of the scientific operating system, leveraging massive GPU infrastructure and specialized AI agent ecosystems. By integrating simulation and AI, we aim to accelerate innovation in critical fields such as drug discovery, materials science, and climate modeling.\n\nA core component of this strategy is the roadmap toward FugakuNEXT, which targets Zettascale performance by 2030. This next-generation system is designed to achieve a 100x leap in application performance through the tight integration of state-of-the-art CPUs and global GPU architectures.\n\nSuccess in this era depends on broad international collaboration to establish common software stacks and secure \"AI factories\". These initiatives focus on high-speed data transfer, open-source AI pipelines, and collaborative learning platforms that maintain data sovereignty while supporting hundreds of thousands of researchers worldwide. By fostering a unified global AI-HPC ecosystem, we can ensure future breakthroughs are limited only by our collective hypothesis generation.
