一切要从股神巴菲特旗下伯克希尔的持仓说起。 在AI浪潮席卷华尔街的最初几年，谷歌的母公司Alphabet曾一度被视为"落后者"，甚至被视为"AI的原罪"——谷歌作为技术领导者越是推动AI发展，就越 可能加速其赖以生存的搜索广告模式的衰落。也因此，当ChatGPT横空出世，谷歌内部一度惊呼"代码红色"，面临生死存亡的威胁。 更新AI认知：从颠覆者到倍增器 一个被初次技术狂热者们所忽略的真理是：AI能力，和所有技术一样，都同样必须进入到具体的用户场景中，才能去为用户创造真正的价值。AI不是一 个凭空存在的"魔法"，它必须依附于"服务"才能生效。 三年前，当GPT骤然兴起，市场的反应是，AI将以一种独立的产品形态重塑技术与用户的关系。这令谷歌陷入了担忧，因为新的交互模式似乎绕开了搜索 框。但三年后的今天，市场开始倾向于认为，AI未必一定是独立的产品形态，也可以融入以往产品或服务，以效率倍增器的形态呈现。 换言之，AI从"颠覆论"过渡到了"倍增论"，也许没有那么性感，但变得务实了一些。 在这种新认知的塑造下，拥有大模型、云服务，以及数十亿用户产品所提供的场景和流量，反而成了谷歌独特且难以复制的护城河。 谷歌大脑和 D ...

Core Viewpoint - The belief that real estate is the primary means of wealth accumulation and social status is being questioned, especially in light of recent failures in property investments and the potential for a reassessment of real estate as a viable investment option [1][4][5].
