风险开始成片兑现：同源底座把保险的大数定律打穿传统保险依赖大数定律，风险单位彼此独立。你家着火不影响我家，某家工厂停产也不会让全球同一时刻一起停产。AI的危险在于把独立性改写成同源性，越来越多的企业依赖同一批基础模型、同一套API、同一云与同一工具链。风险开始像同一场事故，在不同公司、不同流程中被复制粘贴。险企担心的不是某一次聊天机器人犯错，而是一类错误在商业环境里被大规模复用后，带来成片索赔与不可控的责任敞口，于是排除条款开始成为行业趋势，甚至走向标准化。保险业语言里这叫同源聚合。这个触发源往往不是某个公司操作失误，而是更底层的东西，包括模型逻辑缺陷、训练数据污染、关键接口被注入、代理系统在相似指令下出现系统性越权等。一旦同源问题通过API分发扩散，下游成千上万应用可能在同一时间段出现相似失效。理赔就不再是点状事件，而是面状爆发。

With more power for AI functions, Samsung has continued to evolve and expand its AI software, although it seems less of a priority this year. Only one AI feature stood out during my briefing: Audio Eraser. While this launched on the S25, it only worked on audio and video you captured yourself. Now, Samsung expanded it to most major video platforms, including Netflix, Instagram and YouTube, adding the ability to strip out noise and distractions and amplify the volume of voices. It was especially effective with a rowdy replay of an Arsenal football soccer match, and sounded like I was listening to a dedicated commentary channel. Interestingly, unlike many sound editing apps and features, it will work on downloaded videos on those platforms without an internet connection.
