*内容仅为呈现不同市场观点与研究视角，并不意味着本公众号对文中观点结论认可。 当一个科技体系开始把"太空"当作解决产业瓶颈的答案时，它往往已经走到了效率红利的尽 头。 从历史的长河中回望，大国科技体系的衰落，很少是从某一项具体技术的失败开始的，而是从 资本的错配与资源的锁定开始的。 【如需和我们交流可扫码添加进社群】 上世纪 70 至 80 年代，苏联拥有世界顶尖的流体力学家和材料学家，他们将最昂贵的工业资 源、最聪明的大脑全部投入到了太空竞赛与军工体系之中。 然而，正是这种对"宏大工程"的过度迷恋，让他们错过了个人电脑、消费电子与互联网革命。 当硅谷的工程师在车库里编写代码时，莫斯科的精英正在计算如何让更多吨位的载荷进入近地 轨道。 历史总是押着相同的韵脚。 今天，美国科技资本正在出现一个耐人寻味的迹象：为了满足 AI 算力那似乎永无止境的饥渴，一部分资本开始认真讨论——把数据中心搬到太空。这不仅仅是 一个技术设想，更是一个关于资本周期、产业瓶颈与叙事终点的深刻隐喻。 在轨道上，理论上可以获得近乎无限的太阳能，彻底摆脱地面电网的波动与限制；同时，太空 的真空环境避免了大气阻力，且无需面对地面的土地征用、噪音 ...
