谁也没想到，Google I/O现场的最高潮来自"复活"的Google Glass有些翻车了的实时demo。 2025年5月20日，Google的年度开发者大会Google I/O在加州山景城举办。 与去年在举办之前一天被OpenAI"狙击"不同，今年的Google I/O，剑拔弩张的氛围让位给了派对的氛围， 在ChatGPT带来的狼狈之后，Google已经回到了自己的节奏。 是的，它回到了饱和式发布的节奏。当天Google一口气发布了至少十多个AI相关的更新，而其中大多数和 Gemini有关。 简单说，Google主要做了四件事：展示Gemini在多模态上的遥遥领先；给Gemini AI助手做全方位的更新； 让Gemini彻底接管搜索，并让全家桶变成通用Agent；以及令人兴奋的AI+AR眼镜。 这些发布个个重要，但因为AI模型层面本身的进展在过去几年已经吊足了大家胃口，以及Google在此次大 会之前已经发布了Gemini最新的大迭代，现场似乎显得平静。 直到Google Glass的"复活"。它通过live demo彻底点燃了现场。 一、Google Glass is so back 当天的Google ...
