物理 AI 速度快千倍，但西門子稱人類必須簽字批准
西門子稱物理 AI 探索設計的速度比傳統模擬快 1000 倍，但不能批准安全關鍵部件，使人類保持控制。
siemens claims its physics ai models can explore thousands of design variations up to 1,000 times faster than traditional simulation. however, sam mahalingam emphasized that the technology cannot sign off on safety-critical parts, marking a firm limit on automation. this distinction highlights a human-in-the-loop approach for high-stakes engineering where failure is unacceptable. the move signals that despite massive speed gains, industrial ai remains a tool for augmentation rather than autonomous authority.
