我被推荐，和看到太多聊AI风险的，说实话，这些风险我都认同，但是少有把风险和机遇放一起分析最后做出结论的，只聊风险并不会显得自己有多聪明，对未来需求的判断才是最难的，起码华尔街那些人23年GPT到现在，预测英伟达的一年后的盈利预期从来没有对过。 https://t.co/b9Nm961XwB 引用 @TJ_Research：美股的泡沫分为估值泡沫和盈利泡沫 估值现在根本没有泡沫，无论静态还是动态。 盈利泡沫需要向前看，在你听到别人聊泡沫时，记得多问一句，你看到未来的盈利风险在哪里？对建立自己的观点会有帮助的
过去七个交易日，美股因AI变现与资本开支回报受质疑、通胀和油价担忧升温而集中抛售。OpenAI年化营收口径差、Anthropic营收增速放缓及AI基础设施公司融资压力，加上CPI、PPI和布伦特原油走高，加重市场对利率与现金流的担忧。作者认为这属于高速增长叙事下的市场波动，后续关注云巨头财报能否显示收入增长和现金回报。
Wrote this 2.5 years ago. Think it's still mostly right. I hope so. FWIW my personal usage of code peaked around 2017 when I first became deeply informed about Machine Learning and AI. But imagining and adapting to the evolving forest has never required expertise in the trees 引用 @dampedspring：The

JPM’s chart puts global AI compute demand at ~450 GW in 2030 and ~530 GW in 2031. Translating that into capital and revenue shows aggressive these assumptions seem to be. At an illustrative $50B per fully equipped GW (low-end by the way as costs are moving up), supplying 530 GW 引用 @pequityresearch
"In the past year, Devin has gone from writing 13% of Cognition’s production code to more than 90%." This statement is particularly notable given that many consider Cognition as having one of the highest talent density with regards to AI talent and software engineering. 引用 @pmarca：https://t.co/lhP

Thought it'd be helpful to frame this in economic output terms relative to history: Anthropic staff's survey answers imply US real GDP growth of ~18.6% in the 12 months to January 2030 (17.1% in the model's log terms). In the BEA annual record back to 1929, comparable growth https://t.co/j1RJcEaOKC
Fair distinction on the terminology and it's not fair for me to blend them. My broader point is that the investment case still assumes today’s revenue persists and grows so you're still making the same implicit bet. In reality, subscribers can churn, API customers can reduce 引用 @ramez：@ShanuMat

Can anyone see a world in which we need five ( or more if you include non US) frontier models? I don't get how all can win. But not my lane. Like why would we need 5 roughly identical generalized models who leapfrog each other in capabilities instead of 2 or 3?
聊聊CRWV的真实压力以及对能都扛过此次危机？一周前觉得高Beta容易📉的其中一个原因是市场对债务的担心：博通给anthropic和openai担保了近千亿美金，spacex计划借债500亿美金买芯片。当时Crwv的cds暴涨也有了苗头 这周完全成了市场最担心的话题也是大跌的导火索之一。 引用 @qinbafrank：再看上周五推文聊的几个思路，这两天：1）伊朗袭击油轮、胡塞沙特对轰 ，油价不稳住市场也没稳住； https://t.co/5aoaaS2gMx

据英国《金融时报》报道，Anthropic已向黑石开出高于10%的票息，以锚定博通安排的600亿美元债务融资方案中的次级层。黑石基金将投入90亿美元，参与180亿美元B类次级分层；银行牵头420亿美元A类优先担保分层。
华尔街与旧金山科技圈对 AI 产能是否过剩存在分歧，科技圈人士认为，考虑过度建设的可能性就意味着不够相信 AI。未来几个月，若 AI 采用加速或总体生产率证据显现，AI 交易可能大幅上涨；若采用速度或前沿实验室经济性令人失望，也存在下行风险。越来越多人预期未来 18 个月内重演互联网泡沫式崩盘。
美联储主席 Kevin Warsh 表示，AI 将通过改善预测从根本上改变货币政策的实施。他说，未来不久，分析通胀趋势时就不必再用老式模型“折磨”数据。

Figuring out how to prevent AI models from doing “rogue” things is obviously good. But I also agree with Alvaro here. We don’t know how the future will unfold, but extreme concentrated power per se is worrisome and it’s very plausible that creating strong AI will lead to that. 引用 @GroundhogStrat：So
