## Detailed walkthrough ### [00:04](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=4s) The Foundation of AI: Compute, Supply Chains, and Perceptions

The session opens with a brief introduction highlighting that every AI breakthrough relies directly on compute. As demand shifts from training frontier models to enterprise deployment, the challenge expands beyond simply manufacturing more chips to doing so faster, more efficiently, and at global scale. Moderator Gideon Lewis-Kraus (technology writer for *The New Yorker*) introduces the panelists: **Pat Gelsinger** (General Partner at Playground Global and former CEO of Intel) and **Sachin Katti** (Vice President of Compute Strategy and GPT Infrastructure at OpenAI).

Lewis-Kraus frames the core issue based on his recent reporting on the global semiconductor supply chain. He notes two frequent observations: even tech-literate people often understand almost nothing about chips, and chips act as a mirror reflecting an observer's narrow interests. A corporate executive views chips through inference economics, a data center landlord focuses entirely on power, AI critics view data centers as physical symbols of unwanted AI encroachment, and frustrated observers wonder why chips cannot simply be mass-produced like standard widgets. When asked what three fundamental points they would teach a non-specialist, Gelsinger emphasizes that chips are the physical "fuel" or "oil" of a token-driven economy. While humanity's demand for intelligence is virtually unlimited, semiconductor manufacturing faces brutal physical constraints. Building modern capital-intensive foundries requires engineering transistor features down to 2 nanometers—where a human hair looks like a boulder compared to the microscopic structures inside. Gelsinger notes that AI's explosive growth is possible because it builds directly on top of pre-existing internet, cloud, and semiconductor infrastructure rather than starting from scratch.

Adding to this perspective, Sachin Katti highlights **"The Bitter Lesson,"** a famous observation penned around 15 years ago by AI researcher Rich Sutton. The principle states that regardless of algorithmic cleverness or human domain heuristics, throwing more compute at a problem consistently yields superior solutions as scale increases. Katti traces OpenAI's view of model evolution—progressing from basic chatbots to reasoners, agents, AI interns, AI engineers, and ultimately autonomous AI researchers. He explains that OpenAI's future model capabilities and revenue projections are directly mapped to the total volume of compute they can secure over time.

- **Panelists:** Pat Gelsinger (Playground Global / ex-Intel) and Sachin Katti (OpenAI). - **Manufacturing Scale:** Advanced foundries produce 2-nanometer transistors requiring some of the most capital-intensive facilities in human history. - **The Bitter Lesson:** Rich Sutton's paper demonstrates that compute scaling consistently outperforms handcrafted algorithmic optimizations. - **AI Capability Progression:** Chatbots $\rightarrow$ Reasoners $\rightarrow$ Agents $\rightarrow$ AI Interns $\rightarrow$ AI Engineers $\rightarrow$ AI Researchers.

[05:37](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=337s) Is Compute a Commodity? Value Capture Across the Supply Chain

Lewis-Kraus picks up on the analogies to oil and "big blobs of compute," asking whether compute and intelligence should be viewed fundamentally as commodities, and if so, who will capture economic value across the supply chain. Gelsinger points out that value capture has heavily sedimented down to the silicon and infrastructure layer. While model developers hope to capture vast downstream value in the future, the traditional software-as-a-service (SaaS) sector has suffered a massive disruption—what he calls the "SaaS apocalypse"—as software shifts toward chat and agentic interfaces operating over unified algorithmic and data layers. Consequently, semiconductor foundries, toolmakers, and memory manufacturers have seen unprecedented economic windfalls, yielding multi-billion and trillion-dollar valuations for memory suppliers, equipment makers like ASML, and foundries like TSMC. In Gelsinger's words: *"It has never been this good to be a silicon guy."*

Katti responds by outlining OpenAI's mission to lower the cost of intelligence, making it universally accessible. He highlights that the cost of intelligence has been dropping by **10x to 100x every year**—a pace far exceeding historical Moore's Law. Because the global demand for intelligence is effectively infinite, cheaper intelligence continuously unlocks new use cases. While chips and compute are not yet true commodities—evidenced by the vast margins premium chips command today—Katti envisions a future where AI automates the software layer required to translate raw hardware into tokens across any architecture. Once software adapts seamlessly to any underlying silicon, compute will behave far more like a fungible commodity.

- **Economic Shift:** Value has moved away from traditional SaaS software layers down to silicon foundries, equipment makers (ASML), and chip designers. - **Cost Trends:** The cost of delivering AI intelligence has been falling by 10x to 100x per year. - **Future Fungibility:** As AI automates low-level code generation to run models on arbitrary hardware, compute will increasingly behave like a true commodity.

[08:50](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=530s) The "IEEE" Framework and Infrastructure Bottlenecks

Moving into their ongoing work and multi-year outlooks, Gelsinger outlines a four-part engineering framework he summarizes as **"IEEE"**:

1. **Infrastructure:** Massively expanding semiconductors, data centers, and communication fabrics. 2. **Efficiency:** Overcoming today's highly inefficient hardware architectures. Gelsinger bluntly states that *"today's GPUs suck,"* citing severe power limits and the fact that High Bandwidth Memory (HBM) is energy-inefficient despite being the best currently available option. 3. **Energy:** Recognizing that in a digital AI economy, *economic capacity equals energy capacity*. Gelsinger points out a stark geopolitical disparity: China currently has 39 nuclear reactors under active development, whereas the United States has zero. 4. **Economics:** Transforming the unit economics of tokens. Gelsinger argues that token efficiency cannot just improve by 10x—it must improve **10,000x** to sustain the trillions of dollars in global capital expenditure, which will soon be measured as a non-trivial percentage of world GDP.

Katti reflects on his previous tenure at Intel working directly under Gelsinger, joking that he spent years working for Pat. Over the past year at OpenAI, Katti's primary focus has been convincing global leaders to invest heavily across every layer of the physical and virtual infrastructure stack. In the Western world, nearly every layer is severely bottlenecked: data center construction is slowed by permitting and grid interconnects, energy is scarce, fab and memory capacity remain constrained, and integrating components into usable compute clusters takes far too long.

- **Gelsinger's IEEE Model:** Infrastructure, Efficiency, Energy, and Economics. - **Nuclear Disparity:** China has 39 nuclear reactors under construction versus zero in the US. - **Economic Requirement:** Token delivery economics need a 10,000x efficiency improvement to justify global infrastructure CapEx.

[13:18](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=798s) Breaking Bottlenecks: From 3 Years down to 3 Quarters

Lewis-Kraus pushes the panelists on how to accelerate a semiconductor ecosystem that historically took decades to build, noting that titan companies like TSMC and ASML required 40 years to achieve their dominance. Gelsinger outlines specific technical breakthroughs on the horizon: resurrecting progress in lithography beyond current 13.5nm extreme ultraviolet (EUV) systems (where lithography equipment now accounts for half of a fab's total capital cost), integrating memory directly onto compute dies to boost bandwidth by orders of magnitude and reduce inference costs by 50x to 100x, transitioning interconnects from copper to optical networking, and deploying cryogenic cooling for superconducting logic to achieve 1,000x efficiency gains.

Katti focuses on the data center buildout timeline. Today, building a custom data center facility often takes up to 24 months or longer, while TSMC can ramp an entire new chip manufacturing process in just 18 months. Currently, the cycle from initial chip concept to a fully ramped production cluster takes roughly 3 years (9–12 months for design, 3–6 months in the fab, followed by bring-up and datacenter deployment). Katti argues that the industry must compress this entire timeline from **3 years down to 3 quarters**. Achieving this requires standardizing modular data center construction—moving away from bespoke, "stick-built" on-site construction toward robotic prefabrication—and securing direct, on-site energy generation to bypass lengthy power grid interconnection queues.

Gelsinger adds a warning regarding algorithmic shifts: because hardware development takes 3 years, specialized chips optimized for today's separate pre-fill and decode steps may become obsolete by the time they ship. If frontier models begin folding training and inference back together, hyper-specialized accelerator chips risks being algorithmically mismatched for next-generation architectures.

- **Current Hardware Lead Times:** Concept-to-production for new silicon takes ~3 years (9–12 months design, 3–6 months fab, plus bring-up). - **Target Compression:** OpenAI aims to compress chip design-to-datacenter deployment down to 3 quarters. - **Inference Innovation:** Direct compute-on-memory integration could reduce inference costs by 50x to 100x; cryogenic optics offer potential 1,000x efficiency gains. - **Architectural Risk:** Designing overly specialized chips risks mismatch with rapidly evolving algorithmic paradigms.

[18:03](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=1083s) The Ultimate Constraint: Energy Capacity and Token Efficiency

Addressing the overarching limits facing artificial intelligence investments, the conversation zeroes in on energy as the primary upper bound on growth. Expanding AI capabilities relies directly on available power infrastructure, which in the United States is currently growing at a modest rate of 4% to 5% annually—a slight improvement after a dismal decade where growth hovered around just 1% per year. This structural bottleneck means that simply throwing more capital at AI infrastructure will inevitably hit a hard ceiling defined by the electrical grid's total capacity.

To sustain the trajectory of frontier AI models, the industry must tackle the energy challenge from two directions: expanding total supply and drastically reducing consumption. There is an urgent imperative not only to generate significantly more energy overall, but also to deliver that power far more efficiently directly to computing hardware. Ultimately, the central goal for next-generation computing infrastructure must be to dramatically improve the energy required per token produced, ensuring that intelligence can scale within real-world physical constraints.

- **US Grid Growth:** Current energy capacity expansion in the United States is limited to 4%–5% annually, following a decade-long plateau of roughly 1% per year. - **Strategic Imperative:** Future chip and system design must focus on maximizing token output per watt to bypass energy bottlenecks.

Reading summary

OpenAI's Sachin Katti and Playground Global's Pat Gelsinger argue that AI advancement is fundamentally tethered to compute scaling, which has shifted massive economic value into physical silicon and foundational infrastructure. However, sustaining this trajectory requires overcoming severe physical bottlenecks in chip fabrication lead times, power grid capacity, and computing efficiency. Compute Scaling and Shifting Supply Chain Economics (5:37) Invoking Rich Sutton's 'Bitter Lesson,' Sachin Katti emphasizes that scaling compute consistently outperforms handcrafted algorithmic optimizations. OpenAI directly ties its capability roadmap—advancing from basic chatbots to autonomous AI researchers—and projected revenues to the physical volume of compute it can secure. Simultaneously, Katti reports that the cost of delivering intelligence is dropping by 10x to 100x annually, outpacing historical Moore's Law. Pat Gelsinger notes that this dynamic has triggered a 'SaaS apocalypse,' shifting economic value downstream away from traditional software layers and concentrating it in equipment makers like ASML, foundries like TSMC, and memory manufacturers. While premium chips command high margins today, Katti forecasts that compute will gradually become a fungible commodity once AI automates the low-level software layers needed to map workloads across heterogeneous silicon architectures. Overcoming Silicon Architecture and Memory Bottlenecks (13:18) Gelsinger contends that current hardware architectures remain deeply inefficient, arguing that today's GPUs and High Bandwidth Memory (HBM) consume excessive power. Manufacturing advanced 2-nanometer transistors requires extreme capital expenditure, with lithography tools alone accounting for approximately half of a modern foundry's total capital cost. To overcome these physical limitations, Gelsinger outlines emerging hardware interventions: integrating compute logic directly onto memory dies to lower inference costs by 50x to 100x, transitioning chip interconnects from copper to optics, and exploring cryogenic cooling for superconducting logic to target potential 1,000x efficiency improvements. Compressing the Three-Year Infrastructure Deployment Cycle (13:18) Bringing new compute clusters online currently takes roughly three years—spanning 9 to 12 months for chip design, 3 to 6 months in the foundry, and up to 24 months or more for data center construction and bring-up. Katti argues that the industry must compress this entire timeline down to three quarters by replacing bespoke on-site construction with modular, robotically prefabricated data centers and securing on-site power generation to bypass utility connection queues. Gelsinger cautions that long hardware lead times introduce significant algorithmic risk. If frontier AI architectures evolve—such as by recombining pre-fill and decode stages that are currently separated—hyper-specialized accelerators designed during a multi-year cycle risk becoming obsolete by the time they reach production. Energy Capacity and the Token Economics Ceiling (8:50) Framing the challenge through his 'IEEE' model (Infrastructure, Efficiency, Energy, Economics), Gelsinger asserts that in an AI economy, economic capacity directly equals energy capacity. He highlights a severe infrastructure disparity, noting that China has 39 nuclear reactors under active construction compared to zero in the United States, while the US electrical grid expands at just 4% to 5% annually following a decade of 1% growth. Because power grids impose a hard ceiling on compute expansion, both panelists argue that capital expenditures cannot scale indefinitely without radical efficiency gains. Gelsinger estimates that token delivery economics must improve by 10,000x to economically justify global infrastructure investments that are beginning to register as a non-trivial share of world GDP. The central tension facing artificial intelligence lies between the demand for compute scaling and the physical realities of power generation, fab economics, and construction timelines. Whether the industry can compress deployment cycles to three quarters and deliver a 10,000x leap in token efficiency remains an open question that will dictate the economic viability of global AI infrastructure.

精炼阅读摘要

Pat Gelsinger与Sachin Katti指出,尽管前沿人工智能的发展高度依赖算力扩张,但半导体制造、建设周期与电网容量的物理极限正在形成严峻瓶颈,这促使产业链价值向芯片制造集中,并迫使行业寻求万倍级别的能效与交付架构革新。 算力驱动扩张与产业链价值向芯片沉降 (5:37) OpenAI的Sachin Katti援引研究员Rich Sutton约15年前提出的“惨痛教训”(The Bitter Lesson),表明无论算法与人为启发式规则如何精巧,持续堆叠算力在规模化扩展中始终能产生更优解。OpenAI将模型从聊天机器人、推理器、智能体推进至AI实习生、AI工程师及自主AI研究员的技术路径与收入预期,完全与其能够锁定的算力总量直接挂钩。Katti指出,当前提供智能的成本正以每年10倍至100倍的速度下降,这一降幅远超历史上的摩尔定律;随着AI未来实现底层代码自动适配任意硬件架构,算力最终将演变为同质化的通用大宗商品。 然而在现阶段,经济价值正在不可逆地向下游芯片与基础设施层沉积。Pat Gelsinger表示,由于软件形态迅速转向依托统一数据与算法层的对话和智能体交互,传统软件即服务(SaaS)行业遭遇了剧烈颠覆。与此同时,高技术门槛使得半导体代工厂、制造设备商(如ASML)和存储器厂商获得了巨大的估值溢价与经济红利,芯片尚未成为真正意义上的大宗商品,高端硬件仍维持着极高的利润率壁垒。 “IEEE”工程框架与底层硬件效率瓶颈 (8:50) Gelsinger提出了应对未来算力挑战的“IEEE”四维工程框架:基础设施(Infrastructure)、效率(Efficiency)、能源(Energy)和经济性(Economics)。在制造端,建设先进晶圆厂需要制造达到2纳米特征尺寸的晶体管,在这一尺度下人类发丝相比微观结构如同巨石。针对现有计算架构,Gelsinger直言“现今的GPU体验极差”,指出高带宽内存(HBM)虽是当前最佳方案但能效依然低下。他强调,全球基础设施资本支出将很快占据全球GDP不可忽视的比例,Token的经济与能效指标仅提升10倍远不足以支撑这一投资,必须实现10,000倍的能效飞跃。 为突破这一硬件物理极限,行业正在探索底层范式的革新。潜在的技术路径包括将内存直接集成到计算芯片核心上,从而大幅提升带宽并将推理成本降低50至100倍;同时将互连介质由传统铜互连过渡至光网络互连,并部署用于超导逻辑的低温冷却技术,以期带来最高达1,000倍的硬件系统效率提升。 压缩基础设施周期与算法错配风险 (13:18) 从初始芯片构思到大规模集群部署上线的传统周期长达3年,其中设计阶段占9至12个月,晶圆制造占3至6个月,随后还需经历系统调试与数据中心投产。对比台积电(TSMC)可在18个月内推进一代制程、而传统定制数据中心常需24个月以上才能落成的现状,Katti提出必须将从芯片设计到数据中心投运的整体周期从3年大幅压缩至3个季度。实现这一目标的关键路径在于摒弃传统的现场定制建筑模式,转向基于机器人预制的模块化数据中心,并采用现场直连发电以规避电网漫长的并网排队流程。 但加速硬件开发亦伴随着重大的架构错配风险。Gelsinger警告,长达3年的硬件研发周期极易脱离算法演进节奏。如果芯片厂商针对当前大模型独立的预填充(pre-fill)和解码(decode)阶段设计高度专用的加速芯片,一旦前沿算法架构重新将训练与推理融合为一体,这些过度专用化的硬件在正式出厂时便面临技术淘汰与架构失配的风险。 电网容量上限与单Token能效约束 (18:03) 能源供给已成为限制人工智能规模化扩展的最根本上限。Gelsinger提出在数字AI经济中“经济能力等于能源能力”,并指出全球能源基建存在显著差距:中国目前有39座在建核反应堆,而美国处于在建状态的核反应堆数量为零。在整体电网供给侧,美国电力基础设施在经历长达十年仅约1%的极低年均增长后,目前的扩容增速仅回升至4%到5%,难以满足数据中心的爆发式需求。 在电网物理扩容缓慢的刚性约束下,单纯增加资本开支必然会遭遇电力承载上限的强力阻碍。与会者一致认为,前沿模型的可持续发展必须同时依赖能源总供给的提升与系统级能耗的大幅削减,新一代计算芯片与系统设计的核心战略指标,必须转向最大限度降低单Token生产能耗(Token output per watt)。 算力基础设施的规模扩张正面临从微观制造物理极限到宏观电网容量不足的多重制约。尽管模块化数据中心与近存计算等技术为压缩周期提供了可能,但在美国电网扩容缓慢与算法快速迭代的双重挤压下,产业能否及时达成万倍Token能效提升以支撑数万亿美元的资本支出,仍是悬而未决的严峻考验。

```mermaid flowchart TD accTitle: AI时代对算力与芯片的不同认知视角 A["芯片与底层算力"] --> B["企业高管: 模型推理与单位经济效益"] A --> C["数据中心运营商: 电力接入与能源供给"] A --> D["社会大众/舆论: 数据中心对土地与资源的侵占"] A --> E["产品研发/技术团队: 阻碍模型迭代的刚性产能瓶颈"] ``` ### [02:30](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=150s) 石油隐喻与“苦涩的教训”:算力如何决定 AI 的进化阶梯 帕特·基辛格直截了当地指出,“没有底层的物理芯片,就根本谈不上什么算力”。在由 Token(词元)驱动的现代经济体系中,芯片就是支撑运转的基础燃料和“石油”。人类对智能的需求是无止境的,这种贪婪的需求顺理成章地转化为了对底层计算、网络、存储和基础设施的无限渴求。然而,芯片制造却受到极端物理法则与高昂制造周期的严苛制约。基辛格感叹道,制造先进制程芯片是人类历史上最复杂的工程奇迹,比如在 2 纳米晶体管的微观世界里,“人类的一根头发丝相比之下就像是一块巨石,而芯片内部的结构就像一只微不可见的跳蚤”。前端看似只是一个极简的聊天对话框,背后却依托着人类数十年来在互联网、半导体和云计算领域积累的庞大工业遗产,这也是 AI 爆发速度如此惊人的根本原因。 萨钦·卡蒂则引入了人工智能领域著名的“苦涩的教训”(The Bitter Lesson——由 AI 学者理查·萨顿 Rich Sutton 提出)。该理论的核心洞见在于:无论研究人员设计的算法多么精妙,历史一再证明,唯有向系统投入更多算力,才能真正解决越来越复杂的问题。这就是过去十年 AI 发展的铁律。在 OpenAI 的演进图谱中,AI 的形态正在经历清晰的跃迁:从最初的聊天机器人(Chatbots),演化为具备推理能力的逻辑系统(Reasoners),再到具备执行能力的智能体(Agents)。如今,技术已迈入“AI 实习生”(AI Interns)阶段,并在不久的将来迈向“AI 工程师”乃至“AI 自主研究员”。卡蒂坦言,OpenAI 预测自身未来收入与模型能力上限的方式其实极为纯粹和直接——那就是看在特定时间节点上,团队究竟能掌控多少可用算力。 - **微观尺度对比**:先进制程芯片(如 2nm 工艺)的制造复杂度极高,宏观的一根头发丝与芯片纳米级元件的比例差犹如“巨石比跳蚤”。 - **AI 智能能力演进阶梯**:聊天助手(Chatbots) $\rightarrow$ 逻辑推理器(Reasoners) $\rightarrow$ 自主智能体(Agents) $\rightarrow$ AI 实习生(AI Interns) $\rightarrow$ AI 工程师 $\rightarrow$ AI 研究员。 - **算力与能力强挂钩**:前沿模型能力与未来商业规模直接由基础设施所拥有的总算力规模线性推导而来。 ### [05:37](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=337s) 价值沉淀:谁在收割 AI 供应链的终极红利? 针对“石油”的比喻与算力是否会大宗商品化(Commoditization)的疑问,讨论转向了整个产业链的价值分配格局。基辛格明确指出,在本轮 AI 繁荣周期中,真正的财富重心已经发生了剧烈下沉——软件层昔日的辉煌正在被打破,SaaS 行业遭遇了所谓的“SaaS 大毁灭”(SaaS apocalypse)。传统软件被无情解构,取而代之的是由底层模型、数据层、算法层以及前端对话式/智能体界面构成的全新栈道。在这一过程中,巨额的商业价值沉淀到了最底层的半导体与基础设施端。基辛格笑称:“硅芯片厂商从未迎来过如此美好的时代!”从万亿美元市值的存储巨头,到台积电(TSMC)、阿斯麦(ASML)等晶圆代工与核心光刻设备商,硬件与晶圆制造企业成为了最大的赢家。 ```mermaid flowchart TD accTitle: AI时代价值沉淀与分层架构转移 subgraph AppLayer["应用与交互层(价值重构)"] A1["对话界面 / 智能体交互 (Agent Interface)"] A2["传统 SaaS 遭遇重创 (SaaS Apocalypse)"] end subgraph ModelLayer["模型与数据层(未来价值捕获)"] B1["算法与数据治理层"] B2["前沿基础模型提供商"] end subgraph InfraLayer["硬件与基础设施层(当前最大赢家)"] C1["先进制程晶圆代工 (如 TSMC)"] C2["光刻机与核心半导体设备 (如 ASML)"] C3["超大规模 HBM / 存储芯片厂商"] end AppLayer --> ModelLayer ModelLayer --> InfraLayer ``` 卡蒂则从 OpenAI 的使命出发阐述了不同的愿景。他强调,OpenAI 的核心理念是让全人类都能负担并获取智能,因此必须全力推动“智能成本”的雪崩式下降。目前,智能成本正在以每年 10 到 100 倍的速度锐降,这一降幅甚至远超当年的摩尔定律。在卡蒂看来,只要智能足够廉价,就会催生无限的应用场景。为了实现这一目标,算力最终必须具备高度的通用性与可替代性(Fungible)。尽管当前市场因为软硬件生态的壁垒,对不同芯片支付着截然不同的溢价,但随着 AI 逐渐能够自主编写将不同芯片转化为 Token 输出所需的底层适配软件,算力在长期内必然会向大宗商品化的形态演进。 ### [08:50](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=530s) 算力瓶颈与破解之道:基辛格的“IEEE”法则 面对主持人关于两人近年工作与未来布局的询问,现场爆发出一段欢快的插曲。卡蒂打趣道:“过去四年我其实一直在给帕特打工!”因为在加入 OpenAI 之前,卡蒂曾在英特尔担任重要高管,两人不仅是老同事,更是多年战友。玩笑过后,基辛格用自己身为工程师最熟悉的缩写——“**IEEE**”,系统性地概括了解决算力危机的四大核心行动支柱: 1. **基础设施(Infrastructure)**:必须在全球范围内大规模扩建半导体制造工厂、高等级绿色数据中心以及先进通信网络。 2. **能效与效率(Efficiency)**:基辛格直言不讳地批评“当今的 GPU 表现糟糕透顶”("Today's GPUs suck"),不仅极其耗电,在计算架构上也面临严重约束;而当前广泛采用的高带宽内存(HBM)同样效率有限,仅仅是目前技术条件下的无奈妥协,整个 AI 处理架构的效率亟待颠覆性提升。 3. **能源供给(Energy)**:在数字 AI 经济时代,经济产出上限直接等同于可用能源上限(Economic capacity equals energy capacity)。基辛格举出鲜明对比:中国目前有 39 座在建核反应堆,而美国本土的在建数量是“零”。缺乏充沛且稳定的清洁能源输送,算力扩张将寸步难行。 4. **经济效益(Economics)**:现有的 Token 生成经济模型极不划算。未来 AI 基础设施投资甚至将以占全球 GDP 的百分比来衡量,面对数以万亿计的资本开支,AI 的推理与计算经济性不能只提升 10 倍,必须实现 10,000 倍的飞跃。 卡蒂对此深表赞同,并指出西方世界在基础设施的每一个层级都陷入了结构性瓶颈:从数据中心选址审批迟缓、能源接入困难,到晶圆厂与存储产能不足。OpenAI 过去一年的核心工作之一,就是向全社会普及这一严峻现实,推动全产业链共同加速投入,以防算力红利被极少数群体垄断。 ### [12:31](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=751s) 从 3 年压缩至 3 季度:数据中心与芯片体系的革命 针对传统半导体生态系统(如台积电与 ASML)需要长达四十年深厚积累、无法一蹴而就的现实挑战,基辛格与卡蒂给出了激进的技术突破路径。基辛格强调必须“彻底唤醒摩尔定律”。目前半导体光刻成本已经吃掉了晶圆厂近一半的资本支出,行业必须打破 13.5nm 极紫外光刻的物理停滞。未来的芯片架构将直接把存储单元集成堆叠在计算核心之上,从而成倍乃至指数级提升内存带宽,这将使模型推理的成本动态直接改善 50 到 100 倍。此外,从传统的铜互连全面转向光通信网络(Optical Networking),以及引入能带来千倍效率提升的超导低温计算(Cryogenics),都将在本年代末彻底重塑算力底座的经济逻辑。 ```mermaid flowchart LR accTitle: 芯片与数据中心交付周期革命 subgraph CurrentProcess["当前传统周期 (约 3 年)"] direction TB A1["芯片架构设计\n(9-12 个月)"] --> A2["晶圆代工制造\n(3-6 个月)"] A2 --> A3["系统调优、爬坡与\n传统数据中心土建 (2-4 年)"] end subgraph TargetProcess["未来目标周期 (压缩至 3 个季度)"] direction TB B1["AI 辅助快速芯片设计"] --> B2["高效晶圆快速流片"] B2 --> B3["模块化/机器人建造数据中心\n与现场独立供电"] end CurrentProcess -.->|"技术与建造范式重构"| TargetProcess ``` 卡蒂则指出了物理工程维度的巨大痛点:在最佳情况下,在美国建设一座现代数据中心也需要 2 到 4 年,而台积电爬坡一条全新工艺线仅需 18 个月。业内甚至戏称“从芯片概念构思到最终量产交付至少需要 3 年(9-12 个月设计 + 3-6 个月流片 + 调试爬坡)”。OpenAI 的愿景是将整个周期从“3 年”压缩到“3 个季度”。要达成这一目标,必须改变现场定制搭建的传统工法,转向利用机器人技术进行高度模块化、自动化的快速复制,并在电网外迅速部署就地能源方案。 与此同时,基辛格提出了一个发人深省的技术辩证关系:当前行业正在为“预填充(Pre-fill)”与“解码(Decode)”等特定阶段开发专用的定制芯片,但随着算法模型自身的发展,训练与推理正在重新交织融合。这种长周期的专用硬件设计,很可能在三年后量产出厂时发现自己已经被最新的算法演进彻底淘汰。 - **内存带宽与架构重构**:将存储直接堆叠于计算设备上方,有望带来 50 到 100 倍的推理成本降幅。 - **下一代互连与物理层**:光网络(Optical Networking)与超低温超导技术(Cryogenics)将提供高达 1000 倍的能效提升潜力。 - **建设周期目标**:推动“芯片设计 $\rightarrow$ 晶圆制造 $\rightarrow$ 数据中心部署”的全流程从原本的 3 年压缩至 3 个季度。 ### [17:31](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=1051s) 终极硬约束:能源边界与投资理性 在讨论进入尾声时,主持人提出了一个产业层面的普遍担忧:当整个社会将万亿级别的资本以不可阻挡之势砸向从能源、存储到晶圆制造的每一个环节时,是否会引发严重的资源“挤出效应”(Crowding-out effects)以及高度集中的资本错配风险? 基辛格对此给出了一个既务实又充满冷峻逻辑的回答。他认为,物理世界的能源供给本身构成了最天然、最强大的安全阀与理性硬约束。归根结底,算力的物理极限受制于能源,“没有人会为一个连电都通不上的芯片去凭空建造一座数据中心,更不会有人把数十亿美元白白扔进没有电力支撑的裸芯片中”。能源这道不可逾越的物理红线,将倒逼整个算力行业在疯狂的扩张中时刻保持对真实利用率与底层基础设施能力的敬畏。 ### [18:03](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=1083s) 能源供给的物理上限与“每 Token 能耗”挑战 AI 投资与算力扩张的终极边界并非单纯取决于算法或芯片设计,而是受制于底层能源容量(Energy Capacity)这一不可逾越的物理上限。在经历了过去十年年均仅约 1% 的低迷增长后,目前美国的电力容量年增长率勉强提升到了 4% 至 5%,但这依然构成了整个 AI 基础设施扩张的最严苛瓶颈。面对这一硬约束,行业必须从两端发力:一方面需要获取规模庞大的新增能源供给,另一方面必须大幅提升电力从电网输送至计算设备的转换效率,以期在根本上实现“每生成一个 Token 所消耗的能量(energy per token produced)大幅降低”。在点明能源是 AI 算力终极战场这一核心洞见后,主持人向 Pat Gelsinger 和 Sachin Katti 两位嘉宾致谢,整场关于芯片、能耗与下一代算力基础设施的深度对话圆满落幕。 - **能源增长制约**:美国电力供给容量在经历了连续十年年均仅约 1% 的停滞期后,目前年增速回升至 4%–5%,这构成了支撑 AI 庞大投资规模的硬性天花板。 - **核心优化指标**:AI 基础设施与芯片架构演进的关键突破口在于大幅削减“每 Token 生产能耗”(energy per token produced),实现算力能效的比率级跃升。 - **对谈闭幕**:主持人 Gideon Lewis-Kraus 总结发言并向 Pat Gelsinger 与 Sachin Katti 致谢,为本次围绕算力边界与底层约束的圆桌讨论画上句点。 ## Notable quotes > [02:30](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=150s) 没有底层的物理芯片,就根本谈不上什么算力 — 帕特·基辛格 (Pat Gelsinger) > [02:30](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=150s) 人类的一根头发丝相比之下就像是一块巨石,而芯片内部的结构就像一只微不可见的跳蚤 — 帕特·基辛格 (Pat Gelsinger) > [05:37](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=337s) 硅芯片厂商从未迎来过如此美好的时代! — 帕特·基辛格 (Pat Gelsinger) > [08:50](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=530s) 过去四年我其实一直在给帕特打工! — 萨钦·卡蒂 (Sachin Katti) > [08:50](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=530s) Today's GPUs suck(当今的 GPU 表现糟糕透顶) — 帕特·基辛格 (Pat Gelsinger) > [08:50](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=530s) Economic capacity equals energy capacity(经济产出上限直接等同于可用能源上限) — 帕特·基辛格 (Pat Gelsinger) > [12:31](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=751s) 彻底唤醒摩尔定律 — 帕特·基辛格 (Pat Gelsinger) > [12:31](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=751s) 从芯片概念构思到最终量产交付至少需要 3 年……愿景是将整个周期从 3 年压缩到 3 个季度 — 萨钦·卡蒂 (Sachin Katti) > [17:31](https://www.youtube.com/watch?v=ZCgKHvGpxd0&t=1051s) 没有人会为一个连电都通不上的芯片去凭空建造一座数据中心,更不会有人把数十亿美元白白扔进没有电力支撑的裸芯片中 — 帕特·基辛格 (Pat Gelsinger) ## Mentioned Pat Gelsinger (帕特·基辛格), Sachin Katti (萨钦·卡蒂), Gideon Lewis-Kraus (吉迪恩·刘易斯-克劳斯), Playground Global, Intel (英特尔), OpenAI, The New Yorker (纽约客), Rich Sutton (理查·萨顿), The Bitter Lesson (苦涩的教训), TSMC (台积电), ASML (阿斯麦), HBM (高带宽内存), 摩尔定律 (Moore's Law) ## Video description Pat Gelsinger - General Partner; Former CEO of Intel, Playground Global Sachin Katti - Head of Compute, OpenAI Gideon Lewis-Kraus - Technology Writer, The New Yorker AI’s ambitions have never been bigger, and neither have the demands on the infrastructure beneath it.

Original transcript

[0:04] Every AI breakthrough has something in common.  Starts with compute. From training frontier [0:09] models to scaling AI across the enterprise,  compute has become the foundation of the AI era. [0:15] As demand continues to grow, the challenges  are no longer just about building more compute, [0:20] but building it faster, more  efficiently, and a global scale. [0:24] Today, we'll hear from two of the leaders helping  shape the future of compute. Pat Gelsinger, former [0:29] CEO of Intel and now general partner at Playground  Global, has had a front-row seat to major [0:34] technology transitions. Few people understand the  infrastructure powering AI better than he does. [0:39] Sultan Katti is vice president of compute strategy  and GPT infrastructure at OpenAI, where he helps [0:44] build the compute infrastructure that powers some  of the world's most advanced models. Please join [0:49] me in welcoming Pat Gelsinger and Sultan Katti.  So, it's really an honor for me to be here with [0:54] both of you guys today, especially because over  the last couple of months, I've been working on [0:58] a long story about the global semiconductor supply  chain. And there are two related things that I've [1:04] noticed. The first is that even relatively  sophisticated people who really understand AI [1:10] tend to know absolutely nothing about chips.  And the second, relatedly, is that chips are a [1:16] prism through which people really just see their  own interests. And that people at the There are [1:22] depending on where you are in this environment,  you see chips extremely differently. So, [1:27] you know, if you're running a company, you're  you're impressions of chips are largely about [1:31] the economics of inference. If you are involved  in data center leasing, you're thinking about [1:37] energy. If you are You know, this morning I  was listening to Jasmine Sun on Ezra Klein, [1:43] and she's talking about how for like so much of  this AI populist backlash, of course, just sees [1:48] data centers as a symbol of AI's encroachment in  ways that they might not appreciate. And then, [1:55] you know, for a certain kind of person, compute  just feels like this incredibly frustrating [2:00] bottleneck. Like, these are just widgets.  Why can't we make more of these widgets? Um [2:06] so, the first question that I want to open up with  this morning is, if you were talking to, you know, [2:11] a relatively sophisticated interlocutor who  doesn't really know all that much about compute [2:17] or just understands compute in their very limited  sense, what do you think are, say, the three most [2:23] important things that you would want them to come  away with better understanding chips and compute? [2:30] Right. Well, you know, when you think about  compute, it all runs on chips, right? So, [2:34] there ain't no compute without chips sitting under  underneath it. And obviously, you know, the chips [2:40] that sit underneath it, you know, they are the  underlying fuel. They're the oil of a token-driven [2:46] economy, right? That you have. You know, for AI,  I think the demand is unlimited for intelligence. [2:53] So, we see this insatiable demand, right?  Underneath that, you have then almost insatiable [2:59] demand for compute for infrastructure, for memory,  you know, that goes against it. We have severe [3:05] limitations of how we build those chips today. You  know, the capacity of manufacturing is limited, [3:10] right? And it takes a long time to build these  extraordinary capital-intensive factories, [3:16] you know, that go under it with some of the most  sophisticated manufacturing that's ever been [3:22] contemplated in humanity. You know, 2-nanometer  transistors, right? You know, your hair is like [3:28] a boulder compared to, right, you know, a  flea inside of these. It's just incredible, [3:33] you know, what's being done. And all of that, you  know, it just says, "Give me a chat interface." [3:38] I mean, it's just so spectacular. And what's going  on today with AI, you know, it's building on, [3:43] you know, it didn't have to build the internet.  It didn't have to build semiconductors. It didn't [3:47] have to, you know, build clouds. It's building on  all of those, and that's why it is so explosive [3:53] today. Yeah, I I think that summarized what goes  into compute really well and kind of how we hard, [4:01] but at the same time how important the whole  thing is. I think the one maybe thing that [4:06] I'll highlight for the audience, there's this  concept in AI called the bitter lesson. So, [4:11] this was a famous essay written around 15 years  ago by an AI researcher who basically Rich Sutton [4:20] Sutton wrote this, and he basically observed that  it doesn't really matter how smart your algorithms [4:27] are or how creative uh whatever research you're  doing is. The bitter lesson was that as you throw [4:33] more compute at a problem, you just are able to  solve more and more complex problems. And that's [4:40] really been the lesson of this decade. Uh I think  when OpenAI talks about this and consistently, [4:45] we've kind of always talked about AI  evolving through chatbots, reasoners, agents. [4:53] We are now believe at the point where there are  AI interns, and soon uh AI engineers and then [5:00] AI researchers itself. So, the AI itself going  through this progression as if it's growing up [5:06] from just chatting with us to reasoning to  this. And all of that is just scaling laws, [5:12] uh the bitter lesson and showing up. Uh  it's just being more compute thrown at it. [5:16] So, the compute essentially is and this  sounds simplistic, but how we think about [5:22] what the future revenue of OpenAI will be and  what the capability of our models will be, [5:27] we can effectively trace it from how much compute  we will have uh in whatever time frame. So, [5:33] it's that fundamental. So, I want to get to what  you guys are working on in a second, but I want [5:37] to follow up because there's one thread common to  what you guys both said. First, in comparison to [5:42] oil, and then talking about Rich Sutton's bitter  lesson, which also, you know, famous OpenAI paper [5:48] from almost 10 years ago called it a big blob  of compute, right? So, is you know, there's [5:54] been a lot of discussion, especially as far as  inference goes, about like whether we should [6:00] be thinking of intelligence as a commodity. The  question is on the other side of the supply chain, [6:07] is oil the right metaphor? Is it a big blob? Are  we talking about something that is fundamentally [6:12] a commodity or not a commodity? And if so,  if the chips could be considered a commodity, [6:17] if at a certain point, uh intelligence could be  considered a commodity, who then captures the [6:23] value of this supply chain if we're talking about  these as commodities? Well, I mean, clearly you've [6:30] seen the chip guys have gained extraordinary,  you know, value capture in this cycle as well, [6:35] right? You know, the model guys are looking to  capture value in the future. I believe they will, [6:42] you know, but you've hollowed out, right? You  know, value has sedimented down to the, you know, [6:47] silicon and infrastructure layer, right? You  know, software layer as we've known and loved it, [6:51] the SaaS apocalypse has, you know, destroyed that  sector, right? And essentially it becomes a chat [6:56] interface with increasingly agentic level, right?  You know, against models underneath it, right? You [7:01] have a data layer, right? You have an algorithmic  layer and a chat interface, right? And then, [7:06] you know, the belief is is that will fundamentally  change business, business process, and business [7:11] efficiencies at the top. But so far, the silicon  guys are the big winners. I mean, we have, [7:16] you know, a trillion-dollar memory companies. How  that happened, right? You know, just, you know, [7:21] commodities that are extraordinary, you know,  fab companies, ASML, you know, TSMC, you know, [7:26] the silicon guys, you know, it has never been this  good to be a silicon guy. And that's what silicon [7:30] guys are like that. [snorts] Yeah, I I think we  we fundamentally believe intelligence should be [7:37] accessible to everyone, and we need to figure out  how to to driving the cost of intelligence down. [7:42] It has I mean consistently I mean this is a faster  pace than Moore's law ever was, right? So, we've [7:48] been driving cost of intelligence down by 10 to  100 X every year and we don't see that stopping. [7:55] Uh and that's just because the demand for  intelligence is effectively infinite, right? So, [7:59] the more you cheaper intelligence you can deliver  there's more use cases, more demand for it. [8:04] And so, just if I draw the analogy to its  logical conclusion, that will mean that we [8:10] want to make compute very fungible and something  that is able to deliver all kinds of intelligence [8:18] at different price points uh at at the very  affordable price points to the whole world. [8:23] Now, compute today is not yet a commodity, right?  There is different kinds of chips with which are [8:31] obviously the market is paying different margins  for different chips today. But, as AI becomes [8:36] capable of writing the software that is needed to  turn chips into intelligence, chips into tokens [8:43] for any chip, we do think compute becomes uh  more and more a commodity in the long term. [8:50] So, tell us then more specifically, what have both  of you guys been working on in the last few years [8:56] and what do you what's your plan for the next few  years? Yeah, and you know, I I'll simply describe [9:02] it as I E E E, IEEE and being an engineer that  sort of works for me. But, you know, first is lots [9:09] of infrastructure, right? You know, we need more  semiconductors, we need more data centers, right? [9:14] You know, more communications infrastructure,  build out infrastructure. You know, second is [9:19] efficiency. You know, today's GPUs suck, right?  You know, they're very power inefficient, you [9:25] know, they're you know, computationally limited.  Memory today, HBM is a very inefficient memory. [9:31] It's just the best one we have, you know, for  AI modeling today. So, efficiency, we need much [9:38] greater, you know, efficiency in AI processing,  you know, if it's going to reach its potential. [9:43] You know, third, energy, right? In a digital AI  economy, you know, essentially, economic capacity [9:50] equals energy capacity. You know, today, China,  39 nuclear reactors under development. In the US, [9:58] zero, right? You know, we have an energy issue.  We need more energy efficiency and getting power [10:03] delivered to the AI computation, and I just need  more energy, you know, to power it. And finally, [10:09] economics, right? You know, the economics today  suck, right? You know, for uh you know, tokens. [10:15] And you know, as I like to say, it doesn't need  to get 10x better, it needs to get 10,000x better, [10:21] right? Today, you know, we're driving,  you know, trillions of infrastructure [10:25] spend. Imagine that. You know, we're going to  start measuring the AI infrastructure spend [10:30] spend as a percent of world GDP, you know,  going forward. And the economics for that [10:35] are terrible. We have to improve the economics  of AI dramatically from where we are. So, IEEE. [10:43] You asked what we've been working on for  the last 4 years. I've been working for Pat. [10:47] So, [laughter] I was at Intel. I was  literally working for Pat. graduates, so you [10:53] you guys have any stories to tell about working  together? I would Everyone would love to hear some [10:57] tales. I'm sure we will. Uh but uh kidding  aside, I think the last uh year especially [11:02] uh I don't really I mean, the main real  focus has been kind of what Pat alluded to, [11:08] which is convincing the world that we need to  invest in every layer of the infrastructure stack [11:16] because of the potential this technology has  in delivering intelligence to the whole world. [11:20] Uh we are definitely very much in a  world, especially in the Western world, [11:25] where every layer of the infrastructure stack  is bottlenecked. It's more It is bottlenecked. [11:30] Uh it's not easy to build data centers quickly  in the US. It's not easy to find energy in the US [11:38] uh, that we need. Uh, there's not enough fab  and memory capacity to supply the chips we need [11:44] and uh, it's not easy to put it all together  into usable compute. It takes too long. Uh, [11:50] I think all of those layers of the stack  and we have basically spent the time kind [11:54] of convincing that we need to go faster,  make it cheaper, the IEEE concept here. Uh, [12:00] but that that's really important if we are going  to unlock the ability to scale intelligence [12:05] to all the things that we want to do. So, I  think that's how do we get the narrative uh, [12:12] get across the narrative to the world  about what's coming with this technology, [12:16] how capable these things are going to be,  how impactful these things are going to be [12:20] and deduce from there how we need to invest in  every layer of the stack so that we can actually [12:25] get the benefits of this to everyone and not  just the select few. Well, I mean, I'd like to [12:31] push you to be maybe a little bit more specific  about what that looks like because, you know, [12:35] obviously we've had tremendous investments, we've  had CapEx expenditures like nobody's ever seen [12:39] before. But, if you look, you know, Pat, you were  saying that um, right now like the biggest winners [12:45] have been the like the the people at the foundry  level, a place like TSMC or like the tool makers [12:52] like an ASML. But, both TSMC and ASML are they're  not exactly overnight success stories. I mean, [12:59] like these are it took them four decades to get to  where they were. This was a process of building up [13:05] an enormous ecosystem around them. How does one  like so, what are the things that one can do now [13:12] to try to accelerate that given that it's almost  definitionally a kind of generational project? [13:18] Yeah. You know, and there's so many opportunities  here, right? You know, some of those, hey, [13:22] we got to make, you know, semiconductors,  you know, we have to wake up Moore's Law. [13:27] Right? You know, we statically, you know, sort  of landed at 13.5 nanometer lithography. Hey, [13:32] we got to blow the doors open on that. They got to  get more economic. You know, it's now half of the [13:37] capital of a semiconductor fab is lithography.  Right, it's just risen. So, we got to attack that. [13:43] You know, if you look at today's chips, you  know, they're these memory bound, right, [13:48] uh limitations. Okay, you know, almost all of  the new chips will put memory directly onto the, [13:55] you know, uh compute device, right, increasing  by or, you know, exponentially the memory [14:01] bandwidth available. And that will change  the cost dynamics of inferencing, you know, [14:05] by a factor of 50 [snorts] to 100. You know, we  need to move from copper to optical networking, [14:11] you know, way overdue to make that transition.  You know, we're going to start seeing cryogenics, [14:16] right, you know, for superconducting devices  that afford, you know, a thousand X improvement [14:22] in efficiency. You know, these are just some of  the things that will start to crack open the door [14:27] that then fundamentally change the economics,  which I think start to change dramatically, [14:31] you know, late in the decade. And if I can  make my chips do inferencing a thousand times, [14:36] you know, more effectively than yours, you  know, I have changed the economic dramatically, [14:41] you know, forward. And I think some of the capital  risk that people are playing today will start to [14:45] come under pressure late this decade. Not  that we don't need more data center space, [14:49] but what we put into those data centers will  try start to change in a pretty dramatic way. [14:56] Yeah, uh a part covered the chip and the fab  space quite well. All the things that you could be [15:02] doing to kind of change the curve here  effectively. I'll cover the other part of compute. [15:07] Uh I think we need to figure out how to  innovate on just building these things, [15:13] right? So, building a data center today is  a 24-year project in the in some of the best [15:18] case scenarios. Often it can take longer. And so,  how do we actually TSMC can do it in 18 months. [15:24] Yeah. TSMC can ramp a process in 18 months, right?  So, it takes longer to get the data center up and [15:31] running. I think the joke is from concept to a  chip in production is 3 years today. It's not a [15:38] joke, it's the reality, right? So, I think about  a chip, it's usually 9 to 12 months to design it, [15:44] then there's a 3 to 6 month fab cycle, comes  back, you bring it up, and then you ramp it. So, [15:48] it's usually 3 years. And that kind of goes along  with the data center. Our vision is can we cut [15:53] that down to three quarters instead of 3 years?  Can we go from a chip design to a chip ramped up [16:00] in production in a data center in three quarters?  I think many things will have to change to go [16:05] from 3 years to three quarters. So, obviously the  chips and the fab cycles have to get compressed. [16:10] But at the same time, we need to have the ability  to build data centers quickly and repeatedly, [16:16] most likely with robotics, right? The way  we do it stick built today, and every site, [16:21] every site is different, is just not a scalable  approach. How do we get energy quickly on site [16:28] instead of going through the grid, which takes a  long time? And then, how do we make sure that we [16:32] can actually put this back into the grid and make  it a very good citizen of the grid that actually [16:38] helps lower electricity prices for everyone? So,  those are all the other things that have to be [16:44] solved as you solve the chip bottlenecks because  that is actually the big bottleneck. You know, [16:50] it's 3 years to get just go from start to finish  on building a data center. Well, what that tells [16:56] you today, you know, we think about some of the  chip evolution and you know, chips becoming more [17:00] optimized, but in many ways the algorithms may  become less optimized. You know, where you start [17:06] seeing inference and training folding back on  top of each other, and all of a sudden these [17:10] more specialized pre-fill and decode chips, you  know, won't be algorithmically suitable you know, [17:15] for some of the next generation models as well.  So, some of our natural progressions here, [17:20] you know, that people are looking at for  specialization in the data center and the [17:23] chip designs could be exactly the wrong things,  you know, by the time they start bringing those [17:27] products into the marketplace. Well, then do  you worry about I mean like like one obvious [17:32] objection to all of this is that they're going to  be economic externalities in the form of crowding [17:38] out effects both at like when if we're going to  make these kind of investments at every step from [17:43] energy, you know, through that HBM. Like are  you concerned about that kind of concentration? [17:50] Well, you know, one of the good things is, you  know, that fundamentally you're energy limited. [17:54] Right? Nobody's going to build a data center for  chips that you can't power up. Nobody's going to, [17:59] you know, put billions of dollars into chips  that you don't have power for. You know, and I've [18:03] called it, you know, there's an upper bound on how  you fork we get with our AI investments. And that [18:09] upper bound is energy capacity, you know, which  in the US is 4 to 5% per year, right? You know, [18:14] after a dismal decade of about 1% per year. You  know, that is the upper bound on the constraint. [18:21] What goes into that energy, that we need to  make a lot more efficient. But fundamentally, [18:25] we need a whole lot more energy, and  we need the energy to more efficiently [18:29] get to the devices that we're building  so that we improve, right, the, you know, [18:33] energy per token being produced dramatically.  Well, on that note, I think we're about out of [18:38] time. Thank you guys both so much, Pat and Sachin,  for joining us this morning. It's been a pleasure.
