Book Review: The Dialectical Imagination 06/19/2026

Book Review: The Dialectical Imagination The philosophers of the Frankfurt School practiced a technique called negative dialectics, where concepts are defined as much by what you can’t say about them as what you can. Appropriately, the Frankfurt School has ended up defined by what you can’t say about them. You can’t say that they invented a new form of left-wing thought called Cultural Marxism. This would be (according to Wikipedia) , a “far right anti-Semitic conspiracy theory that misinterprets Western Marxism, especially the Frankfurt School, as being responsible for modern progressive movements, identity politics, and political correctness”. You’re not supposed to dub them a transitional stage between Communism and postmodernism. You’re not allowed to speculate that a lot of the academic humanities, as they’re practiced today, descend from the Frankfurt School’s brand of critical theory. You’re not supposed to think of them as the point where the muscular pro-technology leftism of the early 1900s shattered into the pessimistic degrowth leftism of the present. Art is long, life is short. Most of us only manage to not do a few things in our limited span on Earth. But the Frankfurt School managed to not invent so many movements - to not be involved in so many of the crucial ideological shifts of the past century - that they caught my attention. Who were these people? What other aspects of our culture might we be unable to say they were involved in? For answers, I turned to the classic history of the group, Martin Jay’s The basics are simple enough: the School was founded in Frankfurt in 1923. It attracted great philosophers like Max Horkheimer, Theodor Adorno, and Herbert Marcuse. When the Nazis took power in the early 1930s, the mostly-Jewish Frankfurters fled to America, where friendly locals helped them continue their work in affiliation with Columbia University. Mid-century Americans , and when the rise of fascism and World War II started dominating headlines, the German-Jewish Frankfurters were natural experts to help Americans process the situation. By the end of the war, they were firmly established as thought leaders. Some - including Horkheimer and Adorno - returned to Germany to rebuild its intellectual culture from the ruins; others stayed in America and remained relevant through the 60s and 70s. But figuring out what the Frankfurters believed is more complicated. Forget about the thin line between universally-acknowledged fact and fascist conspiracy theory. The School itself was famously coy, worrying that if they explained themselves too clearly, people would caricature their beliefs and integrate them into the existing capitalist system. Even when they did speak “clearly”, it was in the sort of German philosophical register where “the negation of the negation” is a totally normal thing to say. Having only read a single book on them, I will no doubt fall into all the failure modes that they and their successors warned us against. But here are the analogies, intuition pumps, and parables that I found helpful. /episode/index/show/sscpodcast/id/41701160

New Paradigms Won't Save You 06/19/2026

New Paradigms Won't Save You One popular objection to AI concerns is to declare that LLMs can never be AGI. You need a “new paradigm”. Therefore, AGI is so far in the future that it’s not worth worrying about. A common counterargument is to claim that no, LLMs can become AGI. But even without that counterargument, I think the “therefore” fails on its own terms. The key question is: how much of a new paradigm do we need? The landmark discoveries on the road to modern LLMs are something like: 1950s: Neural networks 1967: Multi-layer perceptron 2010: Modern deep learning 2017: Transformer, LLM 2022: RLHF, chatbots 2024: Chain of thought / test-time compute We can think of this as an “evolutionary tree”, where a given LLM (let’s say Claude Opus 4.7) shares a recent “common ancestor” with all other chatbots, and only a very distant “common ancestor” with everything else descended from the multi-layer perceptron. If AGI needs a “new paradigm”, what common ancestor can we expect AGI and LLMs to share? AGI will very likely use neural networks, because the human brain is a neural network and qualifies as an AGI. It will probably use deep learning, because although deep learning isn’t exactly analogous to the brain, it seems like a pretty reasonable way to emulate the brain’s learning algorithms onto computer hardware. Skeptics like Yann LeCun and Gary Marcus usually pinpoint LLMs/transformers as the step where we went wrong. that the first AGIs may be within the deep learning paradigm (but not LLMs); Marcus thinks that they’ll combine insights from deep learning with something else. How soon should we expect a new paradigm as revolutionary as LLMs/transformers? Since we got LLMs/transformers nine years ago, suggests nine more years. How soon should we expect a new paradigm as revolutionary as deep learning? By the same logic, sixteen years from now. Lindy’s Law has a heavy tail, which means we can’t simply halve these to find our 25th percentile estimate. Our 25th percentile estimate for the next advance as exciting as LLMs should be three years from now; for deep learning, it’s five years. So even if you think AGI will require a further paradigm shift as big as the invention of the LLM or as deep learning itself, you should have 25% chance it will be developed in the next 3 - 5 years. Which is about as long as the LLM-only crowd think things will take! This isn’t an excuse for relegating the risk of AGI to some vague indefinite future. It could still be the late 2020s or early 2030s! (Might we expect that low-hanging-fruit effects make the next paradigm harder to find than the last one? In practice, fields get more researchers as time goes on, and . And in fact, the number of AI researchers has grown at an unprecedented pace for a scientific field, and growth will enter an even faster regime once AIs themselves can contribute. Overall these make me think things will go even faster than Lindy’s Law predicts - but I think Lindy’s Law is a useful upper bound.) (Would there still be a long time between the invention of the new paradigm and the point where it could be used to maximum effect? It took five years between the invention of the transformer and ChatGPT, the first commercially-successful transformer-based project. But most of that time was spent scaling up, and we’ve already scaled up. If we invent a new paradigm in 2030, then any frontier lab willing to bet on it can quickly provide it with levels of compute sufficient to train models.) This is my attempt to talk to the new-paradigm-wanters in their own language, but I think there’s also that undermines this worldview. . LLMs still seem to be able to convert scale to results; while this continues, new paradigms won’t be necessary, and frontier labs won’t risk pursuing them. If scaling ever hits a wall, there will be a few months of confusion as frontier labs look over various new-paradigm-proposals that they already have lying around, and throw them at the wall to see what breaks through. Then scaling will continue from wherever it left off. The best way to forecast future AI progress is to extrapolate from current LLM scaling. This should work if LLMs scale all the way to AGI. But it may also work even if they don’t. First, because we might get the new paradigm so soon that it won’t be a significant source of delay. And second, because the most likely place for a new paradigm to start is wherever LLMs stop working, going at the same rate. /episode/index/show/sscpodcast/id/41701105

Nostalgebraist's Hydrogen Jukeboxes 06/13/2026

Nostalgebraist's Hydrogen Jukeboxes , the only good theory of taste is Nostalgebraist’s. He wrote a post called , analyzing the literary output of an AI called R1. This AI tried hard to write good fiction, which was part of the problem. It crammed its stories with what Nostalgebraist called (stealing a term from Ginsberg) the “eyeball kick” - a flashy stylistic move that immediately catches the reader’s attention and “wows” them. Here are examples - some from R1, others from an experimental OpenAI model trained specifically for fiction-writing: “There is a prompt like a spell: write a story about AI and grief, and the rest of this is scaffolding—protagonists cut from whole cloth, emotions dyed and draped over sentences.” “When the jar of Sam’s laughter shattered, Eli found the sound pooled on the floorboards like liquid amber, thick and slow. It had been their best summer, that laughter—ripe with fireflies and porch wine—now seeping into the cracks, fermenting.” “And so I built a Mila and a Kai and a field of marigolds that never existed. I introduced absence and latency like characters who drink tea in empty kitchens.” “The morning her shadow began unspooling from her feet, Clara found it coiled beneath the kitchen table like a serpent made of smoke.” Nostalgebraist and another writer, , catalogue some of the most common AI eyeball kicks, each occurring across multiple LLM models: “An overwhelming reliance on cliche. Everything is a shadow, an echo, a whisper, a void, a heartbeat, a pulse, a river, a flower—you see it spinning its Rolodex of 20-30 generic images and selecting one at random.” “Conjunctions combining one thing that is abstract and/or incorporeal with another thing that is concrete and/or sensory.” “Repetitive writing. Once you've seen about ten R1 samples you can recognize its style on sight. The way it italicises the last word of a sentence. Its endless "not thing x, but thing y" parallelisms…the way how, if you don't like a story, it's almost pointless reprompting it: you just get the same stuff again, smeared around your plate a bit.” /episode/index/show/sscpodcast/id/41630140

Three Model Organisms For Taste 06/13/2026

Contra Everyone On Taste 05/20/2026

Contra Everyone On Taste Last year I wrote , which got many good responses from (eg) , , and . I tastelessly forgot to respond to them until now, but I appreciate how they forced me to refine my thinking. In particular, they helped me realize that “taste” and “good art” are hard to talk about, because the discussions conflate many different things: 1: Sensory Delight. Ode To Joy makes the listener feel joyful. Michelangelo’s David fills the viewer with awe at the human figure. The great cathedrals are impressive buildings, in a way that hits you like a punch to the gut. These judgments are preconscious, widespread, and don’t necessarily require artistic sophistication. 2: Novelty and Innovation: Someone gets credit for doing art in a way that has never been done before. The early Impressionists invented a new way of looking at the world and explored all of its little corners. A modern Impressionist painter may be able to match their technical skill, but not their novelty; therefore, the modern would be a mere curiosity while the originals were great artists. For a modern person to be a great artist, they would have to explore entirely new media - hence the surprising and transgressive nature of modern art. 3: Paying Attention / Pattern Language: Tasteful people, viewing art over the generations and paying deep attention to it, have developed a sense of balance, composition, contrast, and what should and shouldn’t be done. We can debate how predetermined the exact grammar of this language was a priori, but for better or worse people are sensitized to it and will judge works with it in mind. A good work of art should either conform to this language, or defy it deliberately and thoughtfully (that is, in a way that transcends it rather than ignores it). Along with these three big ones, here are smaller ones that might or might not be combinations or subvarieties of these: 4: Context And Discussion: Some great art raises questions, and subsequent great art proposes answers, or variations on the questions, or further elucidates the subject. The great artists of any given time are in conversation with their peers and the great artists of all past ages; new art can be judged on whether it shows awareness of, and contributes to, this conversation. Other forms of context are more personal - is a book about human evil more aesthetic if its author survived the Holocaust? 5: Literal Ability To Understand A Work: You can’t fully appreciate Animal Farm unless you know the history of Soviet communism and recognize the book as an allegory for that history. If someone who knew nothing about this liked it as a cute story about talking animals, their appreciation would be different from (inferior to?) that of more knowledgeable people. 6: Changing Fashions: In 1940, Beaux-Arts and Frank Lloyd Wright were the heights of American architecture. By 1950, nobody who was anybody was doing Beaux-Arts or Prairie; it was all International Style. One could very charitably attribute this to the novelty-seeking drive above; but it’s implausible that Prairie style architecture was novel and beloved in 1940, a few houses completely exhausted its potential, but the explosion of International Style buildings didn’t restore the balance such that the low-hanging-fruit level level was lower in Prairie style again. More likely this was just a fashion effect where Prairie style was cool in 1940, then uncool in 1950. 7: Political And Ideological Point-Making: Great art may convey some truth about the world. This could be a purely aesthetic truth. But in the case of Uncle Tom’s Cabin, the truth was “slavery is bad”. Other truths are conveyed symbolically (for example, cathedrals being shaped like crosses) or through design choices (for example, the austerity of Bauhaus architecture making it more suitable for socialist housing). 8: Ability To Profoundly Affect Or Transform You: Maybe this one is emergent from some combination of sensory delight, novelty and point-making. But some people say they come away from art transformed, in a way which is neither just sensory delight nor just political ideology. Philosophers have argued for millennia about exactly what way this is, but hopefully we’ve all had this experience and can accept an extensional definition. These people enumerated these things to defend taste. I will instead take the bold stand that conflating many different things is bad: it frees people from thinking too hard about any particular one of them, or the ways they interact. Here are my arguments for deliberately ignoring about half of these. /episode/index/show/sscpodcast/id/41360315

Half A Month Of Consolation Writing Advice 05/08/2026

Half A Month Of Consolation Writing Advice This month, rationalist institution is running their second , a bootcamp for aspiring bloggers. Participants have to publish a post a day, or they get kicked out. You can read their posts . I’m too old to manage that pace, but agreed to participate as an advisor. Then I missed the first half of the month because I was on a trip. As compensation, here are fifteen pieces of writing advice for the fifteen days I was absent. 1: Against microdishonesty Sasha Chapin has a piece . Maybe lying gives Sasha writer’s block, but for my last set of mentees it more often just made things sound awkward and unclear. The English language hates the slightest whiff of dishonesty, even levels so small you wouldn’t naturally notice them yourself. It punishes you by making your writing worse. I remember asking one of my mentees to take out a tangential paragraph that didn’t really connect to the rest of the argument. They refused, and awkwardly admitted that it was the one thing they really wanted to say with the essay. They’d written the essay about something else, because the other thing was more presentable. Then they’d smuggled their actual point in as a payload. Clever plan, but your readers will notice. There are countless reasons to lie when you’re writing. Maybe you thought of a really clever introduction, but the thing it introduces is 5% different from the thing you really want to say, so you need to be a little vague and smush them together. Maybe you have a really great perspective on something which is almost like the topic du jour, and you need to make it sound like it’s exactly the topic du jour to get it published. Maybe you can rebut 99 out of 100 arguments for some stupid evil position that you want to debunk, but it would be embarrassing to leave one hanging, so you smudge it together into the other 99 arguments. English will punish you for all these things. Sometimes there’s no better solution and you have to settle, but your readers will notice. /episode/index/show/sscpodcast/id/41211815

Orban Was Bad, Even Though We Don't Have A Perfect Word For His Badness 05/08/2026

Against The Concept Of Telescopic Altruism 04/21/2026

Against The Concept Of Telescopic Altruism I. “Telescopic altruism” is a supposed tendency for some people to ignore those close to them in favor of those further away. Like its cousin “virtue signaling”, it usually gets used to own the libs. Some lib cares about people in Gaza - why? Shouldn’t she be thinking about her friends and neighbors instead? The only possible explanation is that she’s an evil person who hates everyone around her, but manages to feel superior to decent people by pretending to “care” about foreigners who she’ll never meet. This collapses upon five seconds’ thought. Okay, so the lib is angry about the Israeli military killing 50,000 people in Gaza. Do you think she would be angry if the Israeli military killed 50,000 of her neighbors? Probably yes? Then what’s the problem? “But vegetarians care about animals more than humans!” Okay, yeah, they sure do get mad about a billion pigs kept for their entire lives in cages too small to turn around in, then murdered and eaten. Do you think they’d care if a billion of their closest friends were kept for their entire lives in cages too small to turn around in, then murdered and eaten? I dunno, seems bad. Maybe there is some possible comparison where some altruist cares about some set of foreigners more than a comparable set of countrymen? The war in Gaza killed 50,000 people, but the opioid crisis kills a bit over 50,000 Americans per year - is everyone who cares about Gaza exactly equally concerned about the opioid crisis? No, but there’s a better explanation - people care about dramatic deaths in big explosions more than boring health crises, regardless of where they happen. Everyone, lib and con alike, cared more about 9-11 than about a hundred opioid crises, even though the former only killed 4% as many people as the latter. And even the people who care about the opioid crisis usually can’t bring themselves to care about anything on the , which are all extra-boring things like diabetes. Once you match like to like, nope, it’s pretty hard to find a “telescopic altruism” example that stands out from the general background of people having weird priorities. Nearly everyone cares about people close to them more than people far away. If there’s a lib who would attend a Gaza protest instead of getting their deathly-ill kid emergency medical care, I haven’t met them - and the “telescopic altruism” crowd certainly hasn’t provided evidence of their existence. Instead, the people who care about their neighbors 1,000,000x times more than Gazans point to the people who ‘only’ care about their neighbors 1,000x times more than Gazans and say “Look! Those guys care about Gazans more than their neighbors! Get ‘em!” in order to avoid any debate about whether a million or a thousand or whatever is the right multiplier. /episode/index/show/sscpodcast/id/40953860

A Buddhist Sun Miracle? 04/21/2026

A Buddhist Sun Miracle? In 1917, some Portuguese children started seeing visions of the Virgin Mary. The Virgin told them she would enact a great miracle on a certain day in October, and a crowd of 100,000 gathered to witness the event. According to eyewitness reports, newspaper articles, etc, they saw the sun spin around, change colors, and do various other miraculous things. At least a hundred separate testimonies of the event have come down to us, with only two or three people saying they didn’t see it. Catholics continue to bring this up as one of the best-attested miracles and strongest empirical proofs of the faith - including here on Substack, where there was a spirited debate about the event last fall. I did my best to research the event, and the results were and . The main thing I was able to add to the Substack discussion, if not the broader worldwide one, was a survey of similar events. There were apparent sun miracles at various other Catholic sites and apparitions of the Virgin, including a crowd of hundreds of thousands in Italy, and a small town in Bosnia where they seem to happen regularly. But also, people who “sungaze” - a weird alternative medicine practice where people stare at the sun in the hopes that maybe this will help something and they won’t go blind - report sometimes seeing the sun spin and change color in similar ways. And Buddhist meditators report that concentrating very hard on any bright light will cause similar things to happen. Still, the Catholics - especially original Fatima-Substacker Ethan Muse - were not convinced. The other Catholic sightings could have been other real miracles, equally attributable to the Virgin. The sungazers were staring at the sun for a long time, unlike the Fatima pilgrims who just happened to glance up at it. And the meditators were doing sophisticated contemplative exercises, again different from the Fatima pilgrims who just looked up and saw it. These were suggestive, but there was no record of a miracle exactly like Fatima happening within a non-Catholic religious tradition. Until now!

How Natural Tradeoff And Failure Components? 04/21/2026

Every Debate On Pausing AI 04/21/2026

Being John Rawls 04/21/2026

Being John Rawls I. John Rawls was born in Baltimore, Maryland, on February 21, 1921. Not John Rawls the famous liberal philosopher (or, rather, John Rawls the famous liberal philosopher was also born in Baltimore, Maryland on February 21, 1921, but he is not the subject of our story). This is John Rawls the alcoholic. John Rawls the alcoholic was twelve when they lifted Prohibition. He partook immediately, and dropped out of school the following year, supporting himself through a combination of odd jobs, petty crime, and handouts. When he was 41, he committed a not-so-petty crime - killing a man in a bar fight. Although he fled the scene and escaped without consequences, it turned him paranoid. Odd jobs and petty crime were both young men’s games, and the handouts became an ever-larger share of his income. He learned to play the field, peddling the same sob story to the Salvation Army on Monday Wednesday Friday, the YMCA Tuesday and Thursday, and the local churches on weekends. He expected to drink himself to death by age 60, and there wasn’t much to do but wait out the clock. But as he entered his early fifties, the handouts started to dry up. The Salvation Army closed shop, the YMCA pivoted to physical fitness, and even the churches were no longer as charitable as before. One day he ran into a man he’d once seen volunteering at Salvation Army, and asked him what had happened. “You haven’t heard?” asked the volunteer. “None of the rich people donate to us anymore. They’re all giving to this group called the John Rawls Foundation. If you’re in trouble, you should talk to them. They’re swimming in money!” This naturally interested John Rawls the alcoholic, so he obtained their address from the volunteer and immediately headed over to their office building. He was met by a psychologist, who introduced himself as John Rawls (“Not the one the foundation is named after, just a funny coincidence, haha!”) John Rawls Psychologist told John Rawls Alcoholic that their foundation would be happy to help, but that he would have to get through a screening process first. The screening process would involve being administered a certain experimental drug and led through a hypnotic induction. The social worker would record his answers, and, if he passed the test, he would receive a monthly stipend that far exceeded the sum of his previous Salvation Army, YMCA, and church handouts. “Like a truth serum?” asked John Rawls Alcoholic. “Sure, let’s say like a truth serum,” said John Rawls Psychologist. “When will the screening process be?” asked John Rawls Alcoholic. “How about immediately?” asked John Rawls Psychologist. So John Rawls Alcoholic found himself lying on a bed in what looked like a medical examination room, as John Rawls Psychologist shone a piercing light into his eye. /episode/index/show/sscpodcast/id/40953805

Support Your Local Collaborator 04/17/2026

Support Your Local Collaborator Every few weeks, a Trump administration official comes up with an insane plan that would devastate some American industry, region, or demographic. Maybe an Undersecretary of the Interior decides that aluminum is “woke” and should be banned. They circulate a draft order saying it will be illegal for US companies to use aluminum, starting in two weeks, Thank You For Your Attention To This Matter. Next begins a frantic scramble on the parts of everyone affected, trying to make them back down. Industry lobbies, think tanks, and public intellectuals exchange frantic emails, starting with “They said WHAT?”, progressing on to “Oh God we are so fucked”, and occasionally ending in some kind of plan. Sending letters. Phoning members of Congress. Calling up that one lobbyist who had a fancy dinner with Trump a year ago and is still riding that high to claim he has vast administration influence. I’ve been on the periphery of a handful of these campaigns, usually in medicine or AI. The common thread is that protests by liberals rarely work. The Trump administration loves offending liberals! If every Democratic member of Congress condemns the plan to ban aluminum, that just proves that aluminum really was “woke”, and makes them want to do it more. What works, sometimes, is objections/protests from Republicans and Trump supporters. These are hard to get. Trump supporters might support the insane plan. Even if they don’t, they might be nervous to speak up or appear disloyal. You’ve got to find someone who’s supported Trump until now, built up a reputation for loyalty, but this one time they finally snap and cash in some of their favors and agree to speak out. Sometimes it’s because they’re an aluminum magnate themselves and this would destroy their business. Other times they’re just a think tank guy or influencer who happens to be really knowledgeable on this one issue and willing to take a stand on it. By such people is the world preserved. /episode/index/show/sscpodcast/id/40908165

SEIU Delenda Est 04/17/2026

SEIU Delenda Est California lets interest groups propose measures for the state ballot. Anyone who gathers enough signatures (currently 874,641) can put their hare-brained plans before voters during the next election year. This year, the big story is the 2026 Billionaire Tax Act, a 5% wealth tax on California’s billionaires. Your views on this will mostly be shaped by whether or not you like taxing the rich, but opponents have argued that it’s an especially poorly written proposal: It includes a tax on “unrealized gains”, like a founder’s share of a private company which hasn’t been sold yet. This could be the Silicon Valley model of building startups that are worth billions on paper before their founders see any cash. Since most billionaires keep most of their wealth in stocks, any wealth tax will need some way to reach these (cf. complaints about the “buy, borrow, die” strategy for avoiding taxation). But there are better ways to do this (for example, taxing at liquidation and treating death as a virtual liquidation event), other have included these, and the California proposal doesn’t. It appears to value company stakes by voting rights rather than ownership, so a typical founder who maintains control of their company despite dilution might see themselves taxed for more than they have. Garry Tan with reference to Google. However, (?!) that pushes back, saying the proposal exempts public companies like Google. Although private companies would still be affected, this would be so obviously unfair that founders would easily win an exemption based on a provision allowing them to appeal nonsensical results. Still, some might counterobject that proposed legislation is generally supposed to be good, rather than so bad that its victims will easily win on appeal. It’s retroactive, applying to billionaires who lived in California in January, even though it won’t come to a vote until November. Proponents argue that this is necessary to prevent billionaire flight; opponents point out that alternatively, billionaires could flee before the tax even passes (as some . One plausible result is that the tax fails (either at the ballot box or the courts), but only after spurring California’s richest taxpayers to flee, leading to a net decrease in revenue. Some people that it could decrease state revenues overall even if it passed, if it drove out enough billionaires, though others . Pro-tech-industry newsletter Pirate Wires that 20 out of 21 California tech billionaires interviewed were “developing an exit plan” and quotes an insider saying that “if this tax actually passes, I think the technology industry kind of has to leave the state”. Even Gavin Newsom, hardly known for being an anti-tax conservative, that it “makes no sense” and “would be really damaging”. The ACX legal and economic analysis team (Claude, GPT, and Gemini) the direst warnings, but agree that the tax is of dubious value and its provisions poorly suited to Silicon Valley. /episode/index/show/sscpodcast/id/40908115

"All Lawful Use": Much More Than You Wanted To Know 04/02/2026

"All Lawful Use": Much More Than You Wanted To Know Last Friday, Secretary of War Pete Hegseth declared AI company Anthropic a “”, the first time this designation has ever been applied to a US company. The trigger for the move was Anthropic’s to allow the Department of War to use their AIs for mass surveillance and autonomous weapons. A few hours later, Hegseth and Sam Altman declared an agreement-in-principle for OpenAI’s models to be used in the niche vacated by Anthropic. Altman that he had received guarantees that OpenAI’s models wouldn’t be used for mass surveillance or autonomous weapons either, but given Hegseth’s unwillingness to concede these points with Anthropic, observers speculated that the safeguards in Altman’s contract must be weaker or, in a worst-case scenario, completely toothless. The debate centers on the Department of War’s demand that AIs be permitted for “all lawful use”. Anthropic worried that mass surveillance and autonomous weaponry would de facto fall in this category; Hegseth and Altman have tried to reassure the public that they won’t, and the parts of their agreement that have leaked to the public cite the statutes that Altman expects to constrain this category. Altman’s initial statement seemed to suggest additional prohibitions, but on a closer read, provide little tangible evidence of meaningful further restrictions. Some alert ACX readers have done a deep dive into national security law to try to untangle the situation. Their conclusion mirrors that of Anthropic and the majority of Twitter commenters: this is not enough. Current laws against domestic mass surveillance and autonomous weapons have wide loopholes in practice. Further, many of the rules which do exist can be changed by the Department of War at any time. Although OpenAI’s national security lead that “we intended [the phrase ‘all lawful use’] to mean [according to the law] at the time the contract is signed’, this is not how contract law usually works, and not how the provision is likely to be enforced. Therefore, these guarantees are not helpful. To learn more about the details, let’s look at the law: /episode/index/show/sscpodcast/id/40706180

I want to make this contest as blinded as possible, so I’m going to hide that column in the form immediately and try to judge your docs on their merit. (does this mean you can’t say something like “This book about war reminded me of my own experiences as a soldier” because that gives a hint about your identity? My rule of thumb is that if I don’t know who you are, and the average ACX reader doesn’t know who you are, you’re fine. I just want to prevent my friends or Internet semi-famous people from getting an advantage. If you’re in one of those categories and think your personal experience would give it away, please don’t write about your personal experience.) Please make sure the Google Doc is unlocked and I can read it. By default, nobody can read Google Docs except the original author. You’ll have to go to Share, then on the bottom of the popup click on “Restricted” and change to “Anyone with the link”. If you send me a document I can’t read, I will probably disqualify you, sorry. Readers will vote for the ~10 finalists this spring, I’ll post one finalist per week through the summer, and then readers will vote for winners in late summer/early fall. First prize will get at least $2,500, second prize at least $1,000, third prize at least $500; I might increase these numbers later on. All winners and finalists will get free publicity (including links to any other works they want me to link to), free ACX subscriptions, and sidebar links to their blog. And all winners will get the right to pitch me new articles if they want (sample posts by , , , etc). In past years, most reviews have been nonfiction on technical topics. Depending on whether that’s still true, I might do some mild affirmative action for reviews in nontraditional categories - fiction, poetry, and books from before 1900 are the ones I can think of right now, but feel free to try other nontraditional books. I won’t be redistributing more than 25% of finalist slots this way. Your due date is May 20th. Good luck! If you have any questions, ask them in the comments.
