Core Viewpoint - The article discusses the limitations of achieving Artificial General Intelligence (AGI) due to physical and resource constraints, emphasizing that scaling alone is not sufficient for significant advancements in AI [3][20][32]. Group 1: Limitations of AGI - Tim Dettmers argues that AGI will not happen because computation is fundamentally physical, and there are inherent limitations in hardware improvements and scaling laws [8][10][12]. - The article highlights that as transistor sizes shrink, while computation becomes cheaper, memory access becomes increasingly expensive, leading to inefficiencies in processing power [11][17]. - The concept of "superintelligence" is critiqued as a flawed notion, suggesting that improvements in intelligence require substantial resources, and thus, any advancements will be gradual rather than explosive [28][29][30]. Group 2: Hardware and Scaling Challenges - The article points out that GPU advancements have plateaued, with significant improvements in performance per cost ceasing around 2018, leading to diminishing returns on hardware investments [16][17]. - Scaling AI models has become increasingly costly, with the need for linear improvements requiring exponential resource investments, indicating a nearing physical limit to scaling benefits [20][22]. - The efficiency of current AI infrastructure is heavily reliant on large user bases to justify the costs of deployment, which poses risks for smaller players in the market [21][22]. Group 3: Divergent Approaches in AI Development - The article contrasts the U.S. approach of "winner-takes-all" in AI development with China's focus on practical applications and productivity enhancements, suggesting that the latter may be more sustainable in the long run [23][24]. - It emphasizes that the core value of AI lies in its utility and productivity enhancement rather than merely achieving higher model capabilities [24][25]. Group 4: Future Directions and Opportunities - Despite the challenges, the article suggests that there are still significant opportunities for improvement in AI systems through better hardware utilization and innovative model designs [39][45][67]. - It highlights the potential for advancements in training efficiency and inference optimization, indicating that current models are not yet fully optimized for existing hardware capabilities [41][43][46]. - The article concludes that the path to more capable AI systems is not singular, and multiple avenues exist for achieving substantial improvements in performance and utility [66][69].

Core Viewpoint - Michael Burry, a well-known short-seller, is seeking evidence of Nvidia's GPUs being hoarded by customers, particularly photographs, in light of doubts raised about the company's reported sales figures and data center capacity [1][3]. Group 1: Nvidia's GPU Sales and Demand - Nvidia's CEO Jensen Huang claimed that the demand for Nvidia chips remains strong, stating that the company has shipped 6 million Blackwell chips over the past four quarters, with expectations of generating $500 billion in total sales from the Blackwell and upcoming Rubin series products [1]. - An analysis on social media questions whether the reported $111 billion in data center revenue aligns with the claimed shipment volume of Blackwell chips, suggesting a potential shortfall of hundreds of thousands to millions of GPUs [1][2]. Group 2: Energy Requirements and Capacity Concerns - The operation of 6 million Blackwell chips would require between 8.5 GW to 11 GW of power, approximately equivalent to Singapore's total electricity generation capacity, while the U.S. is only expected to add about 8.5 GW of power capacity for data centers between 2024 and 2025 [2]. - This power supply is barely sufficient to match Nvidia's claimed GPU shipment volume, raising concerns about the feasibility of such high deployment levels [2][3]. Group 3: Burry's Scrutiny and Market Concerns - Burry has intensified his scrutiny of Nvidia, focusing on issues such as "circular investments" among U.S. AI companies, revenue recognition methods, and how tech giants depreciate computing equipment [3]. - He has also raised alarms about the sustainability of Nvidia's AI infrastructure spending and has warned about a potential stock market bubble in AI, referencing historical patterns of market downturns following similar wealth distribution scenarios [3].

格隆汇12月19日｜凯投宏观(Capital Economics)在一份报告中称，新兴市场股票的AI泡沫尚未破裂，且 明年可能进一步膨胀。市场经济学家Elias Hilmer称："虽然今年新兴市场股票的估值普遍上涨，但仍普 遍低于美国。"他补充称，新兴市场与美国AI股票之间的巨大估值差距预计明年不会大幅收窄。然而， 如果该AI泡沫像凯投宏观(CE)预测的那样在2027年破裂，较低的新兴市场估值不太可能提供太多缓冲。 在这种情况下，台湾和韩国将面临大幅回调。他称，如果在该泡沫破裂后全球市场出现持续回调，不断 上升的风险溢价将对亚洲以科技股为主的新兴市场构成压力。 ...

近期博通备受市场关注，很大程度上源于其与多家头部人工智能模型提供商的合作。例如，OpenAI已 与博通签订协议，采用其定制的人工智能芯片设计方案。博通也是谷歌TPU项目的重要合作伙伴，负责 TPU芯片的工程实现。受益于大规模数据中心建设带来的定制芯片需求，博通在人工智能芯片市场中所 占份额正持续扩大。博通公司首席执行官陈福阳预计，公司2026财年一季度人工智能半导体业务营收将 同比翻倍，达到82亿美元。但是，与不断增长的营 收预期形成对比的是公司的利润率下降。陈福阳表 示，由于"人工智能业务占比提高"，其2026年一季度毛利率将低于前三个季度水平。毛利较低的定制化 AI处理器销售占比持续攀升，挤压整体获利能力，引发市场对博通业务盈利性可能下滑的担忧。投资 者对大型科技公司在AI投资回报方面的担忧正在加剧。（经济日报记者 周明阳） 受博通与甲骨文业绩引发的人工智能泡沫担忧，加之美联储降息后市场对政策的谨慎情绪，以及美国国 债收益率的上扬，当地时间12月12日，美股主要指数全线下跌。芯片巨头博通股价收盘下跌11.4％，市 值蒸发约2200亿美元。 （来源：经济日报） 转自：经济日报 ...

12月10日，美联储宣布，将联邦基金利率目标区间下调25个基点至3.5%-3.75%之间。这是美联储年内第 三次降息。自再次执政以来，特朗普已多次公开指责美联储降息"动作迟缓"。尽管这一降息决定符合特 朗普的诉求，但他仍然批评降息幅度太小。这表明美联储与特朗普政府之间的分歧仍未有效弥合。外界 对未来美联储货币政策的研判，不能再仅依据传统的经济指标变化，更应考虑政治对货币政策的影响。 美联储内部的分歧也凸显货币政策政治化倾向。在本次美联储投票决定降息25个基点过程中，12名委员 中有3名投下反对票。这是自2019年以来出现反对票最多的情况，反映出美联储内部对于货币政策的分 歧正在加大。特朗普任命的美联储理事斯蒂芬•米兰投下反对票的理由是，他认为应降息50个基点。白 宫国家经济委员会主任哈西特表示，美联储有充足的降息空间，可能还需要进一步降息。特朗普则表示 降息幅度应扩大两倍。 减少财政债务利息支出是特朗普政府要求大幅降息的直接动因。截至2025年12月11日，美国国债超过 37.7万亿美元。按照3.5%的联邦基金利率测算，联邦政府每年需支付利息超过1.32万亿美元。而美联储 每降息一个百分点，联邦政府的债务利息 ...

12月15日（周一），高盛（Goldman Sachs）将2026年铜价预估从此前的每吨10,650美元上调至每吨 11,400美元，理由是精炼铜关税在2026年上半年实施的可能性降低，对可负担性的担忧成为当务之急。 与此同时，由于COMEX期铜上涨，本已创下历史新高的COMEX铜库存仍在持续增加。美国将精炼铜 排除在8月份生效的50%进口关税之外，但仍在对其进行审查。 芝商所发布的数据显示，12月12日COMEX铜库存达到450,618短吨，创历史新高水平。 高盛表示，特朗普政府有55%的可能性在2026年上半年宣布对铜进口征收15%的关税，并计划于2027年 实施，并可能在2028年提高到30%。 该投资银行表示，未来关税的前景可能会使美国铜价高于LME铜，并推升库存，这将收紧美国以外市 场的供应，而美国现在是全球铜价的关键驱动力。 高盛表示："对2027年铜价的预估维持在每吨10,750美元不变，我们预测一旦关税就位和美国以外市场 恢复平衡，那么LME铜价将回落。" 该行还将2026年全球市场供应过剩规模的预测从16万吨上调至30万吨。 （文华综合） 伦敦金属交易所（LME）三个月期铜周一上涨140.5 ...
