Today, I’m talking with Adam Bry, who is CEO of Skydio, the leading US maker of autonomous drones. Before we recorded this episode, I actually got to remotely operate one of Skydio’s drones in the Bay Area from Adam’s laptop in our podcast studio in New York and fly an indoor drone around our office.

Martin Kleppmann, an associate professor at Cambridge and author of Designing Data-Intensive Applications, discusses the evolution of data systems over the last decade, mainly the shift from monolithic databases to modular building blocks. Kleppmann underlines the importance of moving from cloud-centric data storage systems to decentralised data storage similar to Bluesky’s AT protocol. By Martin Kleppmann

You don't really ever have to explain why a universal remote is a good idea. You have a bunch of stuff that needs controlling; this thing controls them all. Many companies have set out to build a product worthy of this idea, and one product came much closer than most. It was called the Harmony, […]

You'd be forgiven for thinking this day would never come. Siri has spent a decade and half somewhere between "sort of useful at a few things" and "utterly disastrous, why did I even try, can it honestly not even set a timer." But the wildest thing just happened: Apple put out a new version of […]

Today on Uncanny Valley, we take an early look at the SpaceX IPO and why you might find yourself among the investors without even realizing it.

In 2019, Alex Vindman testified during President Trump’s first impeachment trial–a decision that ended his military career. Now he wants to challenge the president from the halls of Congress.

https://www.youtube.com/watch?v=VD9zEKQEJxo 这视频深入拆解了人工智能强化学习之父、图灵奖得主理查德·萨顿（Richard Sutton） 在2026年5月共同发表的一篇仅有7页、零算法、零跑分的哲学立场论文。这篇论文提出了 “行动认知 AI”（Enactive Artificial Intelligence，简称 Enactive AI）的概念，并在科技界和资本圈引发了巨大震动（甚至让红杉、英伟达、谷歌联合下注了11亿美元成立新公司）。 视频从 核心概念、哲学脉络、理论内在矛盾、认知科学质疑 以及 产业界的三路对赌 五个维度，极其详细地复盘了视频的所有核心内容： 一、 什么是“行动认知 AI”（Enactive AI）？ 视频强调，全网很多地方都把 Enactive （行动认知/生成认知）和 Generative （生成式 AI，如 GPT、Sora）混淆了，但两者的底层逻辑恰恰相反 [ 00:50 ]： 生成式 AI（Generative AI）： 核心是 续写和预测 。通过已有画面或文本，被动地去预测下一帧、下一个词长什么样 [ 01:07 ]。 行动认知 AI（Enactive AI）： 核心是 在互动中现生成认知 。认知不是大脑被动接收信号并建立静态世界模型，而是“你动了手，世界才向你显现” [ 01:47 ]。 > 举例： 人去拿杯子，不是眼睛先拍下一张静态照片让大脑去死算距离、角度 [ 01:53 ]，而是手往前探的过程中，随着角度、光影的实时动态变化，杯子的形状和可抓取性才在动作里一点点“长出来” [ 01:59 ]。 感知和行动硬死在一起，无法拆分。 这套理论源自认知科学中的 自创生（Autopoiesis）与自主性（Autonomy） [ 02:21 ]。它认为智能体应该像生物一样自我维持、组织，由内在生存需求去塑造感知，而不是一个干等着外部指令输入输出的机器 [ 02:24 ]。 二、 萨顿为什么要发这篇哲学论文？ 萨顿并不是一时性起，这是他为了对抗当前“大模型路线”打出的最后一张哲学底牌： 2019年《苦涩的教训》： 主张人类手写规则干不过堆算力、让机器自己学的通用方法 [ 02:47 ]。 2024年《大世界假设》： 真实世界远比静态内部模型复杂，智能体必须在运行中实时学习 [ 02:59 ]。 2025年《经验时代》： 人类数据是有限的，AI 必须靠自己生成自己的经验长大的 [ 03:12 ]。 2025年9月： 直指整个 AI 行业走错路，大模型堆数据去超智是死路一条 [ 03:19 ]。 这篇论文补上了最后一把火： 之前的论证全是算力、数据和复杂度的“机械账” [ 03:25 ]。而这一次，他第一次把强化学习（RL） 和 认知科学（行动认知）接在了一起，从本体论层面证明： 大模型路走不通，认识世界这件事本身，就只能通过行动和互动的经验来发生 [ 03:39 ]。 为此，2026年初论文共作者创办了 Ineffable Intelligence 公司，号称要造出完全不需要人类数据、靠自己学习的 AI，直接拿到了红杉、英伟达、谷歌 11 亿美元的巨额融资（估值 51 亿美元） [ 03:55 ]。 三、 论文隐藏的两大致命致命逻辑“回旋镖” 视频话锋一转，指出萨顿借来的这套哲学地基里，埋着两根砸中他自己的“大柱子”： 柱子 1：砸中了萨顿的“奖励假设”（自相矛盾） [ 04:35 ] 强化学习的号称教条： 奖励假设（Reward Hypothesis），即所有目标、意图都可以写成“最大化外部给定的标量分数” [ 04:53 ]。David Silver 甚至喊出“奖励就够了” [ 05:13 ]。 行动认知哲学的教条： 自主性（Autonomy），即什么是好坏、成败，标准必须从智能体随时会散架的“物理组织和生存危机”中自发长出来，不能由外部权威操控 [ 05:27 ]。 裂缝： 标准强化学习的奖励函数（Reward Function）是人类设计者用代码硬塞进去的（他律） [ 05:55 ]；而生物判断好坏是为了顶住熵增、维持结构不崩（自主） [ 06:11 ]。论文里作者自己也承认：强化学习的评估标准依然由外部奖励定义 [ 06:38 ]。 内驱动机能救场吗？ 比如好奇心驱动或求知驱动。视频认为不能，因为诸如“优化预测误差”的总结优化目标，依然是人类在架构层死死规定好的，根本不是智能体出于生存忧关的自发需求。没有真正的生命威胁，就没真正的意义生成 [ 07:12 ]。 柱子 2：砸中了萨顿自己的《苦涩的教训》 [ 07:49 ] 萨顿当年痛骂：研究者总忍不住把人类以为的思考结构（比如语法树、手工特征检测器）硬塞进 AI 架构里，这长期必被碾压 [ 08:13

Birgitta Böckeler, Distinguished Engineer at Thoughtworks, returns to discuss the rapid evolution of AI in software delivery. She touches on the evolution from vibe coding, the changing tools landscape and the more autonomous agents that, besides higher velocity, introduce higher risk. By Birgitta Böckeler

We're likely to see more price increases as the big AI companies plan to go public.

I built something I desperately needed: daily AI audio lessons from real developer trends (plus a Dutch coach for inburgering B1). The hardest part wasn't the AI. It was figuring out how to score genuine rising skills vs. one-day noise. I ended up building a cross-day momentum signal that rewards skills accelerating over 3+ days and dampers spikes. But I'm stuck on the next problem: how do you personalize this without storing user data? (I'm privacy-first, so no subscriber DB — Telegram holds the member list.) If you've solved this, I'd love your take. And if you're learning Dutch + coding, I'd appreciate you trying it and telling me what's useless. What I'm curious about: Is the momentum signal actually working — am I surfacing real trends or just noise? Would the Dutch coach be useful for expat developers in NL, or is it too niche? Technical details (for those who care): • 7 sources: GitHub Trending, HN (Who-is-Hiring + front page), Stack Overflow tag deltas, dev.to, Reddit, Lobste.rs • Map-reduce skill extraction with deterministic attribution (corpus scan, not LLM tally) • Grounded briefs: reads actual source text via Jina + Exa, cited sources • Delivered via Telegram (audio + PDF), Spotify podcast, email • Privacy: PII redacted at ingestion, no subscriber data stored Live: https://yusuprozimemet.github.io/LearnX-Radar/ GitHub: https://github.com/Yusuprozimemet/LearnX-Radar (P.S. This is still beta — I'm looking for feedback, not users. If you try it, tell me what's useless, not what's good.)

We're now deep into developer conference season, and one of the themes so far is the relentless conviction from Big Tech companies that AI is going to change everything about how we do everything. Nvidia's Jensen Huang made that clearer than anyone this week, when he described a completely new way of using our laptops […]

On Uncanny Valley, we dive into the IPO bonanza that the top AI companies are embarking on to the point where some real estate listings are looking for not just regular old cash, but Anthropic stock.

Today on Decoder, I’m talking to Ryan Mac, a technology reporter at The New York Times and coauthor of the excellent book Character Limit: How Elon Musk Destroyed Twitter, which came out in 2024. I can’t recommend it enough. I wanted to have Ryan on the show because we’re on the cusp of the SpaceX […]

这视频由知名半导体分析机构 SemiAnalysis 发布，围绕 AI 数据中心网络演进中铜（Copper）与板载共封装光学（CPO - Co-Packaged Optics）的竞争和未来进行了极其硬核且详细的深度拆解。 视频的核心逻辑可分为以下几个关键板块： 一、 背景：铜的物理极限与三大网络层级 1. 铜的物理极限 视频开篇强调，半导体一直依赖铜（如芯片金属层、主板走线、NVL72机架的背板总线）。但当单通道传输速率达到 200 Gbits/second (每路) 及以上时，铜的传输距离极限被死死卡在 2米以内 [ 00:55 ]。超过这个距离，现代 AI 服务器的庞大带宽需求就只能依赖光纤和激光 [ 01:01 ]。 2. AI 数据中心的三大网络层级 [ 01:43 ] 前端网络（Front-end Network）： 负责基础的数据加载、SSH 访问和用户请求，带宽要求最低 [ 01:51 ]。 纵向扩展网络（Scale-up Network）： 连接单机架内的所有计算和网络托盘（如英伟达的 NVLink），让多张 GPU 能以极高带宽、极低延迟像“单张 GPU”一样协同工作 [ 02:07 ]。其带宽需求是 Scale-out 的 10 倍 [ 03:47 ]。 横向扩展网络（Scale-out Network）： 负责机架与机架之间、甚至整个数据中心范围内的服务器互联 [ 03:00 ]。其带宽需求是前端网络的 8 到 10 倍 [ 03:47 ]。 二、 传统可插拔光模块（Pluggable Transceivers）的致命痛点 在需要跨机架的 Scale-out 网络中，目前行业标配是可插拔光模块（如 OSFP、QSFP-DD） [ 04:29 ]。 视频拆解了它的四大组成部分： 物理接口、DSP（数字信号处理器）、TOSA（激光发射组件）、ROSA（光接收组件） [ 05:03 ]。 视频提出了一个颠覆直觉的事实： 耗电和延迟的元凶根本不是激光器（仅占15%功耗），而是 DSP。 [ 06:06 ] 功耗： DSP 消耗了光模块高达 60% 以上 的电能 [ 06:21 ]。 延迟： 信号从电转换到光通常会带来 150 到 200 纳秒的延迟，其中 90% 以上由 DSP 造成 [ 06:28 ]。 为什么必须要 DSP？ 因为 GPU 或交换机生成的电信号，在穿过芯片封装、主板走线到达机架边缘的光模块（约 30 厘米距离）时，信号已经严重衰减和失真，必须通过 DSP 进行放大和“清洗” [ 07:17 ]。而 CPO 的核心存在意义，就是将光学引擎无限靠近源头，彻底消灭 DSP [ 06:57 ]。 三、 从 LPO 到 CPO 的技术演进路径 为了干掉 DSP，行业尝试了多种方案： LPO（线性可插拔光模块）： 做法很大胆，直接拿掉可插拔模块里的 DSP，强行把失真的电信号转成光信号发出去。虽然有用，但极大牺牲了传输距离 [ 08:25 ]。 OBO（板载光学）： 把光模块从机架边缘移到主板上更靠近芯片的位置。但由于距离还不够近，没能彻底干掉 DSP，同时还丢掉了可插拔的便利性，宣告失败 [ 09:06 ]。 NPO（近封装光学）： 将光学引擎移至与 ASIC（交换机芯片/GPU）极近的特殊高特性基板上，是目前正在落地的折中方案 [ 09:38 ]。 CPO（共封装光学）： 终极形态，将光学引擎与芯片直接封装在同一个 Package 上 [ 10:01 ]。 视频中拆解的 CPO 三大阶梯（Tiers）： 第一阶梯（最低限度）： 光学引擎与交换机芯片在同一封装基板上，通过铜走线连接。虽干掉了 DSP，但仍需要 SerDes 进行并行/串行信号转换 [ 10:31 ]。 第二阶梯（中介层集成）： 芯片与光学引擎坐落在同一个硅基或有机中介层（Interposer）上，互连密度大幅提升， 彻底不再需要 SerDes ，实现完全的并行集成 [ 11:01 ]。 终极 Boss 级： 利用混合键合（Hybrid Bonding）等 3D 堆叠技术（2.5D 如台积电的 COW-AMH），将光学引擎直接叠在芯片上方或下方，实现极致的低功耗 [ 11:31 ]。 四、 CPO 的商业落地博弈：Scale-out 网络 CPO 的首个落地目标是替代 Scale-out 网络中的传统光模块 [ 12:46 ]。然而，行业对此产生了严重分歧： 传统可插拔的优势： 坏了极易更换（运维成本低）；标准统一、供应商极多，大厂拥有极强的 价格控制权 且能避免 供应商锁定（Vendor Lock-in） [ 13:29 ]。 CPO 的软肋： 它是封装级别的。如果你买英伟达或博通的 CPO 芯片，你就必须绑定购买他们的整套光学方案；一

Today I’m talking with Harvey Mason Jr., who is CEO of the Recording Academy — that’s the outfit that puts on the Grammy Awards. I last talked to Harvey in 2024, when it was obvious that generative AI would upend the music industry, but still not exactly clear how that would happen. Well, it’s been […]

Michael Stiefel spoke to Sonya Natanzon, about the intersection of technical and social aspects of software architecture. Understanding the business and how a company operates is more important than the specific technologies used. Effective requirements analysis requires focusing on problems to be solved that describe good and bad outcomes, rather than statements of need or solution statements. By Sonya Natanzon
