物理 AI 速度快千倍，但西门子称人类必须签字批准
西门子称物理 AI 探索设计的速度比传统模拟快 1000 倍，但不能批准安全关键部件，使人类保持控制。
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.
