下面是个人理解，不一定对。无论是2B还是2C，AI的核心一定是应用，因为这才能让用户付费，所以 最终软件和互联网应用的利润一定远高于芯片。 原因是市场发现即便像谷歌这样的AI大模型第一股，也需要有大笔的资本开支，软件公司从轻模式变成了重 模式。 从价值投资的角度来看，轻模式当然远胜于重模式，因为轻模式是可以随便止损的，重模式则不能犯 错。 比如你今年花了1000亿美元来买硬件做AI，如果一旦发现技术路线错误，那这1000亿美元就白砸了， 都是沉没成本。 巴菲特最讨厌的就是重模式，无论你今年赚了多少钱，都要投入到新一轮军备竞赛里面。五年过去，十 年过去，现金流没变多，只多了一堆不断折旧的资产。 传统上来说，芯片属于重模式，软件和互联网服务属于轻模式，所以后者估值高很多。但目前软件公司 也投入重金甚至负债做AI，那估值模式就要向制造业看齐了。 反过来说，如果软件和互联网应用都赚不到钱，那肯定也没人去买芯片。从商业逻辑看，前者是甲方， 后者是乙方，甲方肯定握有主导权。 虽然目前看是甲方求着乙方买货，但工业社会长期看缺的不是供给而是需求，供给迟早会跟上，到时候 还是甲方爸爸说了算。 但目前的情况则是，软件的生态出现了 ...
