“AI泡沫”可能要破灭了?华尔街忧心忡忡
Sou Hu Cai Jing· 2025-08-25 15:41
最近一段时间,投资者再次紧张起来,他们担心"AI泡沫"即将破裂。英伟达、CoreWeave、微软、Alphabet的股价明显下跌,越来越多的人认为,AI股票已 经存在泡沫,尤其是那些上市AI企业。面对越来越高的风险,投资者需要考虑抽身离场。 OpenAI创始人Sam Altman认为,在VC支持的私营初创公司中,的确存在AI泡沫。MIT在一份报告中表示,95%的生成式人工智能投资几乎没有为企业带来 收益,半数项目以失败告终,仅5%落地商业化。 Sam Altman并没有指向上市公司,但投资者显然进行了宽泛的解读,将上市公司视为风险所在。MIT的本意并不是劝说投资者离开,而是对整个AI产业进行 批评。 AI项目失败率太高了 在MIT报告中,我们首先要了解"NANDA"概念,它的全称为Networked Agents and Decentralized AI(网络智能体与分布式人工智能),其由MIT提出,旨在 为自主AI智能体打造新协议和新架构。NANDA可能意味着当前的AI方法是无效的,如果企业能够根据NANDA协议开发出更多具有自主决策能力的人工智 能系统,那问题将会消失。 报告调查了150名企业高管和350 ...

AI泡沫下,OpenAI创始人奥特曼的理性与矛盾
Sou Hu Cai Jing· 2025-08-23 13:10
在近期的一次私人宴会上,OpenAI的首席执行官山姆·奥特曼向多位美国AI领域的记者坦诚,他认为当 前AI产业正经历一场泡沫。这一直言不讳的观点迅速引起了业界的广泛关注。 面对记者的直接提问,奥特曼没有回避,他明确表示:"是的,AI产业确实存在泡沫。"他指出,这种泡 沫主要源自投资者对AI技术的过度热情,以及随之而来的对非理性估值的追捧。尽管他认为AI是一项 具有变革意义的技术,但当前的狂热状态与互联网泡沫时期有着惊人的相似之处。 奥特曼进一步解释,AI泡沫的形成部分原因在于用户对AI需求的快速增长,这推动了算力和数据需求 的激增。然而,一旦这种需求放缓,原本被视为资产的算力和数据可能迅速转变为负担。他警告说,这 种转变可能导致一些AI公司面临严重的财务压力。 尽管如此,奥特曼也强调了AI技术的经济价值和长远前景。他指出,AI已经在医疗保健、金融、自动 化等多个领域展现出巨大的应用潜力,并正在创造切实的经济价值。这些有形应用为AI产业提供了一 个坚实的基础,使其不至于像互联网泡沫时期那样,一旦概念破灭就一无所有。 在OpenAI内部,对于泡沫的看法存在分歧。CFO萨拉·弗莱尔在接受采访时表示,OpenAI拥有 ...
科技股发出警告:AI叙事开始动摇,风险正蔓延至“看不见”的角落
Hua Er Jie Jian Wen· 2025-08-23 10:45
长期以来由大型科技股驱动的全球市场,正在显露出疲态。 到目前为止,对科技股和AI有利的,就是对全球股市有利的。但如果科技股和AI真的出了 什么大问题……好吧,后果不言自明。 今年以来,美国乃至全球股市的亮眼表现,几乎完全由少数科技巨头"抬着走"。 这种由少数科技巨头主导的"头重脚轻"的市场结构,正面临着来自AI叙事本身以及私募市场过度集中的 双重考验。一旦科技股,特别是AI概念股的引擎熄火,整个市场的稳定性将面临严峻挑战。正如文章 所言: 以芯片巨头英伟达为例,其市值已高达4.3万亿美元,相当于整个英国富时100指数总市值的1.5倍。数据 显示,美国最大的10家公司占据了标普500指数约40%的权重,并贡献了过去一年该指数三分之一的收 入增长。 这种极端的集中度导致了市场的严重分化:今年以来,标普500指数上涨了9.5%,而追踪小盘股的罗素 2000指数仅上涨4.2%。 看得见的失衡:科技巨头独木难支 AI神话褪色:从"非理性繁荣"到"零回报" 8月23日,英国《金融时报》一篇评论文章指出,本周的科技股抛售不仅是对其高昂估值的警示,更是 一个危险信号:风险可能已从公开市场,渗透至为AI热潮提供巨额资金、却更隐 ...
