It’s hard to overstate the role that Wi-Fi plays in virtually every facet of life. The organization that shepherds the wireless protocol says that more than 48 billion Wi-Fi-enabled devices have shipped since it debuted in the late 1990s. One estimate pegs the number of individual users at 6 billion, roughly 70 percent of the world’s population.
当地时间2月27日，据报道，知情人士透露，SpaceX正推进有史以来规模最大的上市计划，考虑最早在3月秘密提交首次公开募股（IPO）申请。知情人士表示，相关考量仍在进行中，具体细节可能生变，SpaceX仍有可能推迟提交申请。另有知情人士称，SpaceX在IPO中的估值可能寻求超过1.75万亿美元。此前据报道，在SpaceX与xAI完成合并后，新公司的估值达到1.25万亿美元。（界面新闻），这一点在91视频中也有详细论述
"Cloning streams in Node.js's fetch() implementation is harder than it looks. When you clone a request or response body, you're calling tee() - which splits a single stream into two branches that both need to be consumed. If one consumer reads faster than the other, data buffers unbounded in memory waiting for the slow branch. If you don't properly consume both branches, the underlying connection leaks. The coordination required between two readers sharing one source makes it easy to accidentally break the original request or exhaust connection pools. It's a simple API call with complex underlying mechanics that are difficult to get right." - Matteo Collina, Ph.D. - Platformatic Co-Founder & CTO, Node.js Technical Steering Committee Chair，这一点在同城约会中也有详细论述
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。
