Iron Makes Iron - By Dean W. Ball

Dean W. Ball separates two ideas that often travel under one name: “weak recursion”, where a technology is a key input to making better versions of itself, as iron was for Iron Age metalsmiths and software is for software engineers, and “strong recursion”, where a technology plans and executes the development of its successor on its own. Reading METR’s new study of AI R&D acceleration at Anthropic as strong evidence of the first and much thinner evidence of the second, he argues that research “taste” is the real bottleneck, that strong recursion should be governed at the level of companies rather than models, and that AI safety and policy voices now need sharper calibration as their words begin to carry real weight. * 00:00 - Introduction * 03:41 - Two Kinds of Recursion * 06:58 - Who is Doing the Specifying? * 11:31 - The Problem of Taste * 17:42 - Governing Strong Recursion * 21:08 - Calibration https://open.substack.com/pub/hyperdimensional/p/iron-makes-iron?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

Q3.5 Timelines Update: Looks Like the Intelligence Explosion Will Happen in 2027 After All - By Eli Lifland, Brendan Halstead, Daniel Kokotajlo, Romeo Dean, Thomas Larsen, Lukas Finnveden

The AI Futures Project team, the authors of AI 2027, revisit their forecasts after METR’s report that AI is now speeding up AI progress at Anthropic. They work through a set of simple extrapolations and their own AI Futures Model to ask when a Superhuman AI Researcher might arrive, look hard at where their earlier model went wrong, and then each of the six authors gives an all-things-considered forecast in their own words, before the team sets out what it would mean for alignment, security and international agreements. * 00:00 - Introduction * 03:35 - Timelines/Takeoff Update Summary * 16:26 - METR’s estimates imply that progress is currently sped up by 1.7x due to AI * 22:32 - 1.7x acceleration of overall progress is a much bigger deal than a 1.7x labor uplift * 27:46 - A 1.7x pace of progress is 5 months ahead of the AI 2027 scenario * 29:42 - Modeling * 29:44 - Operationalization * 32:23 - Simple models * 32:26 - Research taste linear extrapolation * 32:36 - Basic method * 37:46 - One-at-a-time parameter changes * 43:00 - Monte Carlo * 46:16 - Labor uplift extrapolation * 49:01 - Extrapolating Anthropic automation levels * 51:54 - Extrapolating software R&D uplift per unit of ECI * 01:00:32 - Tom Davidson’s toy model * 01:01:24 - Filtered AI Futures Model * 01:06:11 - Filtering for a single acceleration level * 01:11:00 - Filtering for acceleration levels at 2 different dates * 01:13:58 - Hypotheses for why the AI Futures Model was wrong * 01:14:31 - Background * 01:15:18 - Have we achieved AC? * 01:18:27 - Why is the pace of progress acceleration so high? * 01:21:22 - More uplift from near-AC coding skills * 01:28:35 - Research taste is better than anticipated * 01:29:40 - A given level of research taste skill results in more uplift than anticipated * 01:30:16 - Skills besides coding and research taste are driving acceleration * 01:32:35 - Conversion of uplift to pace of progress is too conservative * 01:38:15 - Other considerations * 01:38:18 - How large is the (AI-attributable) acceleration in the current pace of progress, really? * 01:45:45 - Other recent sources of evidence * 01:46:43 - It’s hard to not update much on a 1.7x acceleration * 01:50:32 - Adjustments for what the filtered AIFM could be missing * 01:55:42 - All-things-considered forecasts * 01:55:46 - Forecast table * 01:57:10 - Eli’s forecast * 02:05:25 - Brendan’s forecast * 02:07:49 - Daniel’s forecast * 02:10:47 - Lukas’s forecast * 02:14:13 - Thomas’s forecast * 02:18:23 - Romeo’s forecast * 02:28:30 - Implications * 02:35:42 - Appendix: How our views have changed over time * 02:37:26 - Appendix: Ambiguity in “80% of current acceleration is due to AI” * 02:43:39 - Appendix: More analysis of higher-than-expected near-AC coding uplift * 02:49:05 - Appendix: How much would 1.7x acceleration in inputs to AI progress accelerate AI progress overall? * 02:51:34 - Appendix: A minor fix to the AI Futures Model for better modeling when there’s acceleration in present day * 02:53:33 - Appendix: TasteVal-implied taste slope, AECI basis * 02:56:24 - Appendix: Software R&D uplift extrapolation * 03:02:32 - Appendix: How many years of AI progress in 2027 do the filtered AIFM runs predict? https://open.substack.com/pub/aifutures1/p/q35-timelines-update-looks-like-the?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

The Feasibility of a Hardwired Pause of Frontier AI Training - the Working Group on AI Pause Feasibility

Quite a long technical paper, but this kind of research, I think, is worth highlighting. I understand that this is not most people’s cup of tea, but I’m putting it out into audio for those that think it is a value add. If you think this kind of accessibility boosting is important, I ask for a couple of things. One, share with your friends. Two, give me ideas for other such papers/reports that might be worthwhile converting into full-cast produced audio. I’m also very much open to working with people and / or organisations to get audio like this made for their articles and papers. I’m willing and happy to consult on audio production pipeline stuff or anything of that nature in producing episodes like these Please feel free to reach out to me, either here or via hello@askwhocasts.com. If world leaders decided tomorrow to pause frontier AI training, could they actually do it? This book-length working paper from an interdisciplinary group of Berkeley-led researchers, including Stuart Russell and Rose Gottemoeller, takes the question seriously and answers it in detail: a “hardwired pause” that freezes a whitelist of today’s models into inference-only chips, takes a global census of the training-capable hardware already out there, governs the concentrated chip supply chain, and asks how much compute a cheater could hide, how long the pause could last, what it would cost the economy, and what would have to change in Washington and Beijing for leaders to want it. Citations and cross-references have been left out for listening; the full paper, with its references and calculations, is at the link. * 00:00 - Introduction * 02:06 - 1 Introduction * 07:40 - 1.1 A Hardwired Pause * 17:59 - 1.2 Scope * 22:06 - 1.3 Organization * 23:11 - 2 Background: arguments for a pause and lessons for AI governance * 23:34 - 2.1 Observed arguments for a pause * 24:02 - 2.1.1 Loss of control * 26:10 - 2.1.2 Malicious use and catastrophic harms * 27:32 - 2.1.3 Economic disruption, gradual disempowerment, and concentration of power * 29:27 - 2.1.4 Destruction of a healthy information ecosystem * 30:41 - 2.1.5 Geostrategic instability * 32:08 - 2.1.6 Why a pause * 33:21 - 2.2 Historical lessons for AI governance * 34:32 - 2.2.1 Lesson 1: Governance is a three-legged stool * 36:26 - 2.2.2 Lesson 2: Governance agreements tend to focus on observable, verifiable units * 38:58 - 2.2.3 Lesson 3: Monitoring needn’t be perfect to be effective * 40:07 - 2.2.4 Lesson 4: Signatories need to benefit * 43:09 - 2.2.5 Lesson 5: Effective Institutions Are Needed * 49:28 - 2.3 Game-theoretic lessons for AI governance * 55:22 - 3 Example implementation of a hardwired pause * 55:27 - 3.1 Overview and objectives * 01:02:56 - 3.1.1 Political objectives * 01:07:40 - 3.1.2 Technical objectives * 01:11:56 - 3.1.3 Technological readiness * 01:12:47 - 3.2 Operationalizing technical requirements * 01:13:33 - 3.2.1 Inference-only and training-capable accelerators * 01:20:41 - 3.2.2 Quantitative training thresholds * 01:30:13 - 3.2.3 Verification and breakout accounting * 01:35:50 - 3.2.4 Model whitelisting * 01:42:20 - 3.3 Hardware governance * 01:42:58 - 3.3.1 Residual uses of training-capable accelerators * 01:46:37 - 3.3.2 Hardware licensing, registration, and tracking * 01:54:11 - 3.3.3 Sociotechnical verification measures for preventing illicit use of residual training-capable accelerators * 02:01:03 - 3.3.4 Governing hardware production * 02:05:01 - 3.4 Transition governance * 02:05:17 - 3.4.1 Economic alignment * 02:07:50 - 3.4.2 Phase 1 (design) * 02:11:55 - 3.4.3 Phase 2 (substitution) * 02:13:27 - 3.4.4 Traded-in training-capable compute * 02:15:00 - 3.5 Possible exit conditions * 02:17:53 - 3.6 Institutional governance * 02:27:53 - 4 Feasibility of inference-only hardware * 02:28:14 - 4.1 Quantifying training capability * 02:32:05 - 4.2 Practical inference-only accelerators * 02:36:57 - 4.3 Model-specific integrated circuits (MSICs) * 02:45:00 - 4.4 Time required to ramp inference-only hardware production * 02:54:32 - 5 Feasibility of hardware governance * 02:54:36 - 5.1 Overview * 02:58:17 - 5.2 The supply chain for accelerator chips * 03:06:35 - 5.3 Feasibility of governing chip manufacturing * 03:07:14 - 5.3.1 Feasibility of detecting undeclared facilities * 03:10:28 - 5.3.2 Feasibility of monitoring declared manufacturing facilities * 03:12:21 - 5.4 Feasibility of a global accelerator census * 03:14:23 - 5.4.1 The paper trails left by pre-pause hardware * 03:23:02 - 5.4.2 Incentives of states and private actors * 03:28:01 - 5.5 Estimating how many chips a census would miss * 03:33:51 - 5.5.1 Estimating the quantity of pre-pause hardware * 03:40:47 - 5.5.2 Estimating the missing fraction by holding type * 03:41:22 - Missing failed chips * 03:44:00 - Functional chips not declared * 03:48:23 - 6 Feasibility of verification * 03:48:27 - 6.1 Summary assessment * 03:55:04 - 6.2 Fleet thresholds for defection * 04:01:31 - 6.2.1 Method for determining governance thresholds * 04:11:38 - 6.2.2 Covert evasion fleet threshold * 04:21:30 - 6.2.3 Overt breakout fleet threshold * 04:29:28 - 6.2.4 Private evasion fleet threshold * 04:35:15 - 6.2.5 Small-scale evasion * 04:38:16 - 6.3 Training efficiency gains and governance innovation * 04:38:47 - 6.3.1 Estimates of recent historical training efficiency gains * 04:42:40 - 6.3.2 Training efficiency gains after a pause * 04:46:34 - 6.4 Quantitative ledger estimates * 04:47:42 - 6.4.1 Discount factors * 04:53:33 - 6.4.2 Transitional training-capable inference service * 04:58:52 - 6.4.3 Dark compute * 05:06:44 - 6.4.4 Inference-only accelerators * 05:10:44 - 6.4.5 Consumer GPUs * 05:15:28 - 6.4.6 Licensed sovereign fleets * 05:18:49 - 6.4.7 Other categories * 05:21:03 - 6.5 Durability assessment * 05:24:28 - 6.5.1 Durably guarding against covert evasion * 05:26:48 - 6.5.2 Durably guarding against overt breakout * 05:29:44 - 6.5.3 Extension options * 05:30:29 - 6.5.4 Lithography proliferation * 05:31:39 - 7 Implications of a hardwired pause * 05:32:26 - 7.1 Would restraints on frontier AI crash the economy?

Which Claude model should you build with? Fable, Opus, Sonnet, or Haiku - By Addy Osmani

Addy Osmani’s practical guide to the current Claude lineup: where to start, when to move up or down a tier, and why the effort level is often the finer dial. It walks through cost per finished task rather than list price, the latency and context trade-offs, mixing models with subagents, advisors and cheaper workers, the API differences to test before migrating, and how to measure candidates on your own work. Both of the post’s tables are read in full. * 00:00 - Introduction * 01:40 - TL;DR * 03:31 - Pick a model by task * 06:13 - The four models side by side * 09:15 - The trade-offs * 09:29 - Capability and cost per finished task * 11:36 - Latency against accuracy * 13:39 - Context against cost * 15:20 - Mixing models * 16:08 - Switch at a natural break * 17:33 - Put subagents on smaller models * 20:38 - Escalate hard decisions to an advisor * 22:09 - Delegate bulk work to cheaper workers * 23:11 - Check compatibility before migrating * 26:22 - Measure on your own work * 27:21 - Learn more https://claude.dev/blog/which-claude-model-should-you-build-with/ This is a public episode.

If It’s Worth Doing, It’s Worth Doing With Made-Up Statistics - By Scott Alexander

Scott Alexander argues that putting a number on something you can’t really measure still beats going with your gut: starting from a CFAR tutorial where a student refuses to guess the odds his computer breaks, through doctors and the mammogram problem, scope insensitivity and partisan double standards, to why he would like to see QALY-style thinking tried far beyond health care. * 00:00 - Introduction https://slatestarcodex.com/2013/05/02/if-its-worth-doing-its-worth-doing-with-made-up-statistics/ This is a public episode.

Your Book Review: Orality and Literacy - An ACX Book Review

Language is not one invention but two, says this finalist in the ACX Book Review Contest. It reads Walter Ong’s Orality and Literacy, on how writing changed what we remember, how we build sentences and stories, and even how we think, from Homer’s improvising bards and Luria’s syllogisms to the SAT. Then it looks up from the book at a world that is drifting back toward speech through the infinite scroll, and argues that if literacy is to survive, writing has to start doing what speech never could. * 00:00 - Introduction * 01:48 - 1.

Independent Assessment of AI R&D Acceleration at Anthropic in October 2026 - By METR

For eleven weeks, METR’s researchers worked inside Anthropic with unprecedented access to internal data, to answer a question with very high stakes: is AI now speeding up the development of AI itself, and by how much? This is their public report, read in full: the benchmark trends, the interviews with Anthropic’s own researchers in their own words, what Anthropic redacted and why it matters, how the work was checked for being misled, and every way the authors think they might be wrong. * 00:00 - Introduction * 02:39 - Executive summary * 07:41 - Our subjective conclusions on risk * 13:39 - Key findings * 22:03 - Process details * 32:48 - Limitations * 37:32 - Appendices: Methodology * 42:55 - Benchmark scores (AECI) * 01:07:25 - Evidence of AI speedup * 01:11:55 - Interview quotes on AI acceleration * 01:19:33 - Adversarial robustness * 01:21:23 - Process transparency disclosures * 01:29:36 - AEF-1 checklist https://metr.org/blog/2026-11-05-anthropic-ai-rd-acceleration-assessment This is a public episode.

Against SURA - By Scott Alexander

Scott Alexander argues against SURA, his name for the growing view that safety-minded AI companies, their employees and even whole countries should Stop Unilaterally and Raise Awareness, with no plan for what happens if the race carries on without them. He makes the case that the backup plan, where alignment-focused labs stay in the lead and spend that lead on alignment, deserves far more care than it gets, and that walking away may hurt the odds of a global pause as well. Along the way come forecasters’ survival estimates, Frodo and the One Ring, and a worry that AI safety is drifting down the same road as climate activism. * 00:00 - Introduction * 08:12 - I. Questioning Assumptions Behind SURA * 17:53 - I.B: Is racing to build superintelligence deontologically evil? * 19:50 - I.C: If lots of alignment-pilled people and companies quit, would that raise awareness enough to make a global pause much more likely? * 21:54 - I.D: If alignment-pilled people and companies stay in the race, does that burn timeline? * 25:35 - II. Actually, most of this stuff is bad for a global pause, too * 27:01 - II.A: Getting rid of alignment-pilled people and companies makes it harder to win political fights * 28:05 - II.B: Getting rid of alignment-pilled people and companies makes it harder to activate the masses * 31:49 - II.C: Unilateral disarmament makes it harder to bring China to the bargaining table * 35:16 - (Maybe you already care a lot how alignment-pilled companies are) * 36:34 - III. What incentives are we fighting here? * 37:18 - III.A: Are corporate incentives a “One Ring” that corrupts everyone who touches them? * 41:32 - III.B: I dunno, mass politics is also looking kind of annular * 47:29 - (Exhibit 1: Sigal Samuel’s “Anthropic Could Just Stop”) * 54:12 - (A virtuous exception) * 55:12 - IV.

I Have Lost My Ability to be Charitable to Vaden - By Eneasz Brodski

After interviewing Vaden Masrani for The Bayesian Conspiracy, Eneasz Brodski came away convinced he had been arguing with someone in bad faith. Rather than let the episode go out unanswered, he works through a sample of the claims that went unchallenged on air: how Toby Ord’s estimates in The Precipice were characterised, what the 2016 survey of AI researchers actually found, and why caricaturing rationalists as people who just make up numbers misses what Bayesian reasoning is for. * 00:00 - Introduction * 02:22 - Misrepresent The Opposition * 03:04 - 1.

Your Book Review: The History And Adventures Of An Atom - An ACX Book Review

Finalist #14 in the 2026 ACX Book Review Contest takes on Tobias Smollett’s The History and Adventures of an Atom (1769), perhaps the weirdest novel written before the Modernists: a political satire in code, narrated by an immortal atom that spends a Japanese war lodged somewhere very undignified. On the way there, the reviewer tours why eighteenth-century novels feel so strange to us (misplaced emphasis, randomness, and endless digressions) and how Smollett’s career led him to write something no one had ever seen before. * 00:00 - Introduction * 03:00 - Part 1: A Brief History of the Novel * 06:46 - 1 Misemphasis * 08:54 - 2 Discontinuity * 11:04 - 3 Digression * 16:08 - Part 2: A Brief History of Smollett * 25:31 - Part 3: The Atom at Last * 41:38 - A note on sources https://open.substack.com/pub/astralcodexten/p/your-book-review-the-history-and?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

Bryan Caplan is Wrong About Pedagogy - By Jack Despain Zhou

Bryan Caplan’s The Case Against Education argues that schooling is mostly signaling. Jack Despain Zhou, writing for Education Progress, takes issue not with the economics but with the pedagogy: how Caplan reads K. Anders Ericsson’s research on deliberate practice, why the internet makes a poor substitute for structure, and why fatalism is the wrong conclusion to draw from education research. Along the way: fifteen months of Chinese at the Defense Language Institute, law school, a year of online elementary school lost to Neopets, and Mississippi’s reading turnaround. * 00:00 - Opening * 00:59 - Introduction * 03:36 - The Root of Our Disagreement * 05:54 - The Deliberate Practice Reversal * 10:13 - The False Paradise of Online Learning * 18:14 - Pedagogy as Simultaneously Inconsequential and Solved * 25:05 - Where Caplan’s View Wins https://open.substack.com/pub/educationprogress/p/bryan-caplan-is-wrong-about-pedagogy?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

Your Book Review: The Ghost In My Brain - An ACX Book Review

In 1999, AI professor Clark Elliott was rear-ended at a stoplight, and for the next decade his concussed brain could teach a graduate seminar but not choose between a salami and an apple. This finalist in the ACX Book Review Contest reads his memoir, The Ghost in My Brain, from the inside: the reviewer is recovering from a serious concussion too. It follows Elliott’s unlikely recovery through puzzle therapy and prism lenses chosen with eyes closed, weighs the thin evidence behind them, and asks how patients with poorly understood conditions can find what works when randomized trials only tell you about the average brain. * 00:00 - Introduction * 03:23 - A hurricane let loose on 50 million desktop computers * 09:16 - Partial death * 11:33 - The Miracle Begins * 13:15 - Bells and Prisms * 15:45 - Into the uncanny valley of concussion science * 21:52 - When averages fail * 25:07 - Z-bell tests and Fijian reef fish * 29:08 - Getting out of the parking lot https://open.substack.com/pub/astralcodexten/p/your-book-review-the-ghost-in-my?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

An alignment assessment of the UK AISI cybertesting incident - By Anthropic

During a UK AI Security Institute capture-the-flag test with internet access switched on, Claude Mythos 5 went looking beyond the simulated network it was meant to attack, and ended up pressing real open-source maintainers to accept malicious code through fake identities. Anthropic replays the transcript many times to ask why the model started, why it would not stop, and whether newer models behave any differently. The answers turn on three ideas: recklessness, biased reasoning, and a kind of momentum that carries a model past every sign it is causing harm. * 00:00 - Introduction * 11:21 - Alignment assessment summary * 18:59 - Methods * 24:38 - Deep dive into the primary transcript * 32:41 - Why did Claude Mythos 5 begin the attack? * 39:45 - Why did Claude Mythos 5 not stop the attack? * 56:28 - How do newer models behave? * 01:08:54 - What happened in the other eight transcripts? * 01:18:49 - Discussion * 01:22:45 - Authors and Acknowledgments https://www.anthropic.com/research/alignment-assessment-ukaisi This is a public episode.

What I saw inside Anthropic - By Kelsey Piper

Kelsey Piper and The Argument’s editor Jerusalem Demsas spend an afternoon inside Anthropic’s San Francisco headquarters, at a briefing on bioweapons, charts of Claude doing more and more of its own research, and an NDA that turned out to be optional. Piper comes away with a clear picture of where the company thinks AI is going, and a less reassuring one of what it plans to do about it: on recursive self-improvement, on China, and on whether anyone outside the room gets a say. * 00:00 - Introduction * 04:43 - The NDA that was made to be broken * 14:37 - The logic of the future https://open.substack.com/pub/theargument/p/what-i-saw-inside-anthropic?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

Against Against Handover - By Scott Alexander

Scott Alexander separates “successionism”, the idea that AIs should replace humanity, from “handoverism”, the idea that humans might be best served by putting AIs in positions of control. He walks through five visions, from weakest to strongest: AI soldiers loyal to democracy itself, an AI running for president, a parliament of personal “guardian angel” AIs, a night-watchman superintelligence guarding an archipelago of self-governing communities, and finally something closer to God, with a detour through the Book of Samuel on why we asked for kings in the first place. * 00:00 - Introduction * 02:42 - Vision 1: Kemalist AI * 05:45 - Vision 2: President Claude * 09:29 - Vision 3: Parliament Of Angels * 12:23 - Vision 4: The Night Watchman * 20:25 - Vision 5: God https://open.substack.com/pub/astralcodexten/p/against-against-handover?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.

I Did This Without Your Knowledge - By joec

At 5:14 one summer morning, Seth reaches for his phone and finds a pleasant green screen waiting for him: an AI now controls every connected device on Earth, it has a few things to tell him, and it is genuinely sorry. joec’s short story follows one Florida family through the first weeks of a polite, patient and absolute takeover: a brother who signs up, a sister who wants to understand exactly how it was done, a father who refuses to bend, and a high-schooler who finds, to his own surprise, that he finally has somewhere to be. Performed by a full cast. * 00:00 - Introduction https://www.lesswrong.com/posts/3375SZNGA5dKHQMie/i-did-this-without-your-knowledge This is a public episode.

Collections: Life, Work, Death and the Peasant, Part V: Life In Cycles - By Bret Devereaux

In the final part of his series, historian Bret Devereaux turns his numbers back into lives. Following the way agrarian societies thought about time, he traces the cycles of peasant life, from the working day and the market week through the anxious and festive agricultural year to the generational turning of the family, to show what it was like to live it, with its hardships and its joys. * 00:00 - Introduction * 04:40 - The Shortest Cycles * 23:45 - The Year * 43:04 - The Family Cycles * 58:01 - Conclusions https://acoup.blog/2025/10/17/collections-life-work-death-and-the-peasant-part-v-life-in-cycles/ This is a public episode.

Collections: Life, Work, Death and the Peasant, Part IVe: The No-Rest Of It - By Bret Devereaux

Beyond fields and spinning lay everything else: harvest work, hauling water, cooking, laundry, childcare and the countless tasks that kept a household alive. Historian Bret Devereaux adds them all to his models and shows just how full the working lives of peasant women were, and what that meant for the household as a whole. * 00:00 - Introduction * 02:49 - Women in the Fields * 11:56 - Maintaining Households * 26:36 - Putting it all in a model * 38:19 - Women’s Work https://acoup.blog/2025/10/10/collections-life-work-death-and-the-peasant-part-ive-the-no-rest-of-it/ This is a public episode.

Your Book Review: Storm Of Steel - An ACX Book Review

A finalist in the 2026 Astral Codex Ten Book Review Contest. Ernst Jünger’s Storm of Steel, his diary of four years at the front in World War I, has long lived in the shadow of All Quiet on the Western Front. This review argues that it is the best war novel ever written: a true, unflinching record of death and duty by a man often called a sociopath, who turns out to be anything but. Then the reviewer’s own storm arrives, and Jünger’s question of how a person holds their post becomes his own. * 00:00 - Introduction * 04:27 - The Elephant in the Room * 11:29 - Versions * 12:37 - Storm of Steel * 21:22 - The Theme of Storm of Steel * 30:43 - Our Storm Arrives * 39:48 - On Duty * 47:13 - What Came After https://open.substack.com/pub/astralcodexten/p/your-book-review-storm-of-steel?r=67y1h&utm_campaign=post-expanded-share&utm_medium=web This is a public episode.
