听了张月光（妙鸭相机创造者）三小时创业访谈后的几个想法。关于 AI 朋友为什么必须会变、为什么需求感比满足感更重要、以及'道升术降'对产品和团队意味着什么。播客 reaction，不是系统分析——几个聊到的点碰巧跟我自己做 AI 伴侣的经验高度吻合。

Reactions to a three-hour interview with Zhang Yueguang (Miaoducamera creator, ~$40M raised for 'AI friends'). On why AI companions must evolve, why the feeling of being needed matters more than satisfaction, and what 'Dao rises, skill fades' means for products and teams. Not a systematic analysis — a few ideas from the podcast that happened to align closely with my own experience building AI companions.
