凤凰网科技讯 北京时间12月1日，据科技网站TechCrunch报道，美国当地时间11月30日，ChatGPT迎来 问世三周年纪念日。这款聊天机器人引爆了生成式AI市场，但是或许也催生出了一场泡沫。 2022年11月30日，OpenAI向世界推出了一款新产品，并轻描淡写地将其描述为"一个名为ChatGPT的模 型，它能以对话方式互动"。 这种格局导致市场呈现出更为极端的头部集中现象。标普500指数是按市值加权的，而这七家公司如今 占指数权重的35%，相比三年前的大约20%有显著上升。 泡沫？ 这股热潮还能持续多久？除了英伟达CEO黄仁勋(Jensen Huang)外，越来越多的AI企业高管开始承认， 行业可能正身处泡沫之中。 "有人会在AI领域损失惨重。"OpenAI CEO萨姆·奥特曼(Sam Altman)在8月与记者共进晚餐时表示。 同样地，Sierra CEO兼OpenAI董事长布雷特·泰勒(Bret Taylor)也认为行业正处于"泡沫"之中，并将其与 上世纪90年代末的互联网泡沫相提并论。他预测，虽然个别公司可能会失败，"但AI将重塑经济格局， 就像互联网一样，未来必将创造巨大的经济价值"。 再过 ...

Summary of Key Points from the Conference Call Industry Overview - The discussion revolves around the concept of market bubbles, particularly focusing on the technology sector and historical parallels with the dot-com bubble of the late 1990s and early 2000s [6][7][24]. Core Insights and Arguments - **Innovation and Folly**: The U.S. is characterized by a culture of innovation that often leads to "creative destruction," where companies innovate themselves to failure, resulting in mass bankruptcies and job losses [3][5][6]. - **Historical Context**: The analysis begins with a retrospective on the "profitless dot-com" bubble of the 1990s, emphasizing that many misinterpret the nature of that era, which was driven more by infrastructure investment than by profitless companies [7][8][14]. - **Market Dynamics**: The NASDAQ index's performance during the late 1990s was largely influenced by profitable large-cap companies, contrary to the narrative that it was primarily driven by unprofitable dot-coms [10][14]. - **Investment Patterns**: A significant amount of capital was funneled into data transmission infrastructure, with companies like AT&T and MCI investing billions annually, which created an overbuilt supply without sufficient demand [17][21][20]. - **Current Trends**: The current AI boom is drawing parallels to past bubbles, with major companies like Microsoft, Google, and Nvidia committing substantial investments in AI infrastructure, raising concerns about sustainability and potential overvaluation [43][44][48]. Important but Overlooked Content - **Capital Cycle Theory**: The concept of Capital Cycle Theory is introduced, suggesting that stock market peaks often occur midway through investment booms, indicating a pattern that may repeat in the current market [50]. - **Stock-Based Compensation**: There is a notable increase in stock-based compensation today compared to 25 years ago, which may exacerbate the effects of market bubbles [30][31]. - **OpenAI's Financials**: OpenAI's commitment to $1.4 trillion in spending over the next eight years, with revenues and losses significantly lower than this figure, highlights the speculative nature of current investments in AI [45][46]. - **Nvidia's Role**: Nvidia is positioned as a central player in the current AI landscape, with its technology being critical across various applications, suggesting a potential for significant market influence [48][49]. Conclusion - The analysis emphasizes the cyclical nature of market bubbles, the importance of understanding historical precedents, and the potential risks associated with current investment trends in technology and AI sectors [50][51].

The final month of the year gets underway on Monday, and investors will be looking for a smoother month to round out the year after choppy November trading saw the Nasdaq Composite (^IXIC) snap a seven-month winning streak while the S&P 500 (^GSPC) moved back to within 1% of a record high. On Friday, markets ended the week by notching a fifth straight session of gains to close out the up-and-down month in a holiday-shortened trading session. And despite snapping its monthly winning streak, the Nasdaq is a ...

他的过往记录包括著名的准确预测互联网泡沫，但也包含一些未应验的警告，例如预测标普500指数可 能从峰值下跌75%——比2008年金融危机的低点更糟。当《纽约时报》在2010年报道爱德华兹时，他们 指出，这位面带微笑、穿着勃肯鞋的分析师自1997年以来就一直预测美国股市将出现日本式的停滞（他 在接受《财富》杂志采访时重复了这一预测）。 尽管如此，爱德华兹仍坚持认为，当前情况与1990年代末的纳斯达克泡沫有明显的相似之处：科技股估 值极高，一些美国公司的远期市盈率超过30倍，而这都由引人注目的增长叙事所支撑。爱德华兹认为， 正如上世纪90年代科技、媒体和电信（TMT）行业吸引了大量（有时是浪费的）资本投资一样，今天 的狂热与那个早期时代如出一辙。不过，有两个关键差异可能导致这次的结果要糟糕得多。 阿尔伯特·爱德华兹（ Albert Edwards ），经济学 家、全球策略师及极端熊市论者。图片来源： courtesy of Albert Edwards 亚洲股市下跌，欧洲股市持平，但美国股市投资者却无视这些不利因素，重燃对美联储将于12月降息的 希望，期待新一轮低成本资金为资产市场注入活力。各大股指再度上涨。 上 ...
