Memory的纪要整理和交易思路的分析，可以参考下面文章： 存储行业趋势和分析 先更新一下最新的DRAM和Nand的价格： 随着超大规模企业资本支出增加、人工智能推理需求及估值变化，让市场更关注当前内存周期回升的持 续性；尽管 AI 资本支出和估值处于高位，但历史数据显示内存行业尚未接近峰值。所以关于Memory的 Super Cycles这个概念，之前野村提到过，大摩也在提这个概念。 当前市场让我们想起一句老话：历史不会简单重复，但总会有些相似之处。这次是AI推理驱动的需 求，上一次则是云计算的兴起。 在这个月UBS的memory monthly中，也表示由于demand的增长大于supply的增长，因此明年短缺会一直 存在。 1. 在周期上升阶段，对估值应更宽松而非保守。 通过研究过去周期的驱动因素，大摩可以为当前市场找到应对策略。基于这些分析，大摩给出以下几点 建议： 2. 对盈利预期应保持乐观而非谨慎，尤其是在超级周期中，价格上涨往往被低估。 3. 在寻找退出点时，采取逆向思维，提前在周期峰值前行动。 深入分析与展望 | | | Q124 | Q224 | Q324 | Q424 | 2024 | Q ...

Core Viewpoints - Karpathy believes that achieving AGI will take approximately 10 years, and current optimistic predictions are often driven by funding needs. He uses the metaphor "summoning a ghost rather than building an animal" to emphasize that AI generates outputs by mimicking internet data, which is different from biological evolution of intelligence [3]. - He highlights the inefficiencies of reinforcement learning (RL), noting issues such as high variance and noise, which he compares to drawing supervisory signals through a straw. He also points out that automated credit allocation and LLM judges can be exploited, limiting their development [3]. - Karpathy identifies cognitive deficiencies in LLMs, stating they lack continuous learning, multimodal capabilities, and emotional drive, relying instead on context windows rather than long-term memory. He warns of the risk of "model collapse," leading to decreased diversity in generated data [3]. - He argues that AGI will not trigger an economic explosion but will instead integrate smoothly into a 2% GDP growth curve, continuing the automation wave. The process of technological diffusion and social adaptation will be gradual, with no evidence of "discrete jumps" [3]. Education and Adaptation - Karpathy has established the Eureka educational institution, aimed at redesigning the education system to help individuals enhance their cognitive abilities in the AI era, preventing marginalization by technological advancements. Its core mission is to create efficient "ramps to knowledge," enabling learners to maximize their "Eurekas per second" [10]. - He emphasizes the need for time and educational support for AI development rather than relying on short-term technological breakthroughs. He does not foresee AI replacing human labor in the short term but rather focuses on cultivating human capabilities to coexist with AI through education, such as promoting multilingualism and broad knowledge [10][11]. - Karpathy's core viewpoint is not one of skepticism towards AI but rather an emphasis on the gradual development of AI and the proactive adaptation of humanity. He believes that AI will not rapidly disrupt the world but will require long-term optimization, with humans needing to enhance their skills to thrive alongside AI [11].
