在2024年1月，我去了香港和韩国，意识到单身现象的上升。 通过收集更多数据，我发现欧洲、拉丁美洲、北美和北非也有同样的趋势。 当男性和女性可以选择时，他们只会在对方迷人、有趣和合作的情况下留下来。 在父权制国家，女性通过社交媒体“文化跳跃”，提高标准，要求更好。 全球范围内，标准的提高恰逢许多人在核心社交技能上挣扎——因为他们要么处于荣誉文化和性别隔离中，要么被高度吸引的媒体所吸引，花更多时间独处，进而面临心理健康问题。 简而言之，年轻人越来越渴望爱情，但找到爱情变得越来越困难。

So after all these hours talking about AI, in these last five minutes I am going to talk about: Horses. Engines, steam engines, were invented in 1700. And what followed was 200 years of steady improvement, with engines getting 20% better a decade. For the first 120 years of that steady improvement, horses didn't notice at all. Then, between 1930 and 1950, 90% of the horses in the US disappeared. Progress in engines was steady. Equivalence to horses was sudden.
