科技巨头们的"蜂巢思维"又发作了。 这一次，他们集体将目光投向了同一个目标：把数据中心建到太空去。 埃隆·马斯克在社交平台上的连番"轰炸"，率先点燃了这把火。但他并非孤军奋战，亚马逊和蓝色起源创始人杰夫·贝索斯、谷歌前CEO埃里克· 施密特早已是此理念的信徒，"芯片教父"黄仁勋也已高调入局。 2025年11月份，谷歌宣布将在2027年前发射原型卫星，测试其AI芯片的太空性能。上周，初创公司Starcloud甚至声称已在搭载英伟达芯片的卫 星上，训练出了首个太空大语言模型。 这一"太空狂想"固然令人心潮澎湃，但细究之下，其背后却可能隐藏着巨头们更为清醒甚至焦虑的认知：他们或许认为，地球已难以承载AI发 展所需的庞大计算力与能源。 更值得玩味的是，除了应对现实挑战，这一概念对于某些推动者还有着另一层意义。 这不只是技术畅想，也是一场资本叙事。 例如，有望在明年进行IPO的SpaceX，就急需一个能引爆市场的故事。在已有的火箭与星链叙事之 上，若再加上"太空AI基础设施"这个光环，无疑将使其估值获得巨大想象空间。 正如马斯克曾通过Optimus人形机器人等举措，对特斯拉所做 的那样。 然而，理想越宏大，质疑声往往也 ...
