1. Pulse: These days my morning work routine starts with trying to replicate this functionality through the use of multiple prompts and GPTs, so I am looking forward to when then feature comes to cattle class subscriptions.

   Sam Altman@sama · Sep 25

   Today we are launching my favorite feature of ChatGPT so far, called Pulse. It is initially available to Pro subscribers.
   
   Pulse works for you overnight, and keeps thinking about your interests, your connected data, your recent chats, and more. Every morning, you get a custom-generated set of stuff you might be interested in.
   
   It performs super well if you tell ChatGPT more about what's important to you. In regular chat, you could mention “I’d like to go visit Bora Bora someday” or “My kid is 6 months old and I’m interested in developmental milestones” and in the future you might get useful updates.
   
   Think of treating ChatGPT like a super-competent personal assistant: sometimes you ask for things you need in the moment, but if you share general preferences, it will do a good job for you proactively.
   
   This also points to what I believe is the future of ChatGPT: a shift from being all reactive to being significantly proactive, and extremely personalized.
   
   This is an early look, and right now only available to Pro subscribers. We will work hard to improve the quality over time and to find a way to bring it to Plus subscribers too.
   
   Huge congrats to @ChristinaHartW, @_samirism, and the team for building this.

2. YouTube Star MrBeast Is Building an Entertainment Empire - Bloomberg: Beast Industries sounds like a regular corporation with regular corporate problems.

   Right now, however, Beast Industries is hemorrhaging money. It’s had three years of losses, including more than $110 million in 2024. The viral videos account for all of it, overwhelming the profits from Feastables. Donaldson has been spending between $3 million and $4 million on every video he produces for the main YouTube channel, most of which lose money. In 2023, Beast spent $10 million to $15 million shooting videos it never released to the public because they weren’t up to its standards. He also lost tens of millions of dollars producing Beast Games, a popular show for Amazon Prime Video in which 1,000 people competed for $10 million by, among other things, moving a 10,000-pound boulder.

   This is going to revolutionize education 📚
   
   Google just launched "Learn Your Way" that basically takes whatever boring chapter you're supposed to read and rebuilds it around stuff you actually give a damn about.
   
   Like if you're into basketball and have to learn Newton's laws, suddenly all the examples are about dribbling and shooting. Art kid studying economics? Now it's all gallery auctions and art markets.
   
   Here's what got me though. They didn't just find-and-replace examples like most "personalized" learning crap does. The AI actually generates different ways to consume the same information:
   
   - Mind maps if you think visually
   - Audio lessons with these weird simulated teacher conversations
   - Timelines you can click around
   - Quizzes that change based on what you're screwing up
   
   They tested this on 60 high schoolers. Random assignment, proper study design. Kids using their system absolutely destroyed the regular textbook group on both immediate testing and when they came back three days later.
   
   Every single one said it made them more confident.
   
   The part that surprised me? They actually solved the accuracy problem. Most ed-tech either dumbs everything down to nothing or gets basic facts wrong.
   
   These guys had real pedagogical experts evaluate every piece on like eight different measures.
   
   Look, textbooks have sucked for centuries not because publishers are idiots, but because making personalized versions was basically impossible at scale. That just changed.
   
   This isn't some K-12 thing either. Corporate training could work this way. Technical documentation. Professional development.
   
   Imagine if every boring compliance course used examples from your actual job instead of generic office scenarios.
   
   We might have just watched the industrial education model crack for the first time. About damn time.

Ignoring the hype up top, Google does seem to be creating some practical tools with LLMs. With base LLMs getting quite good now, I wonder if the next unlock is in creating tools with customized workflows for specific tasks. Wrappers.

2. And the amazing thing is that the opposite works too!

   I think I mentioned this before but I was a national speech and debate octafinalist in high school and I was able to parlay that into a job running a debate program at an ambitious charter middle school in college.

   My approach was the exact opposite of this. Like half the kids were TERRIFIED of public speaking and were only doing it because their tiger moms insisted they had to (and the other half LOVED the attention).

   I had a lot of trouble getting the scared kids to open up and one day I asked one of the youngest ones what made her so afraid of speaking in front of the class, especially since they were all her friends.

   And she told me she was afraid she’d say something dumb or make a mistake and everyone would make fun of her. And that they’d laugh and laugh at her if she froze up.

   The next day I asked the class if anyone was scared of being made fun of and all the shy kids raised their hands.

   Now I don’t actually know if this is the same pathology in adults with fear of public speaking but I suspect it’s similar, and now I’ll get to how I addressed it which worked fabulously.

   First I told them that this was a ridiculous fear and that no one would make fun of them. But of course that doesn’t do anything lol. But then I told everyone to rip out 10 pieces of paper from their notebooks and crumple them up.

   And I told them I was going to give a speech. I told them if I said “uhh” or “um” or used any filler words they were to throw a paper ball at me and shout “shame!” 3 times pointing at me.

   And I gave a terrible speech. And they loved it! It was so much fun for them.

   But then! I had the students give speeches with the same rules, starting with the confident ones.

   After the third student the shy ones were volunteering.

   After the lesson I explained to them that we had accomplished 2 things:

   1. We had demonstrated how absurd such a reaction really is, because none of them would have ever reacted in that way if they weren’t specifically asked to, and none of them had any actual malice even when they did shout “shame” at their classmates

   2. Everyone had experienced the comically worst case scenario imaginable of public speaking and survived!

   So they became the rule during EVERY class and I was told by the other teachers that my shy students had started leading presentations and speaking up in class and some of them asked me how I worked with them.

   They were HORRIFIED when I told them lol.

   But it worked!

   This reminds me of Boggarts in the Harry Potter books.

   This guy is founding an evangelical church, and I find his ecosystem fascinating. First for its stunning similarities to venture-capital-funded tech start-ups, and then for its simplicity and open-heartedness. None of the dynamics in church planting are unique or even particularly rare, but they are unobfuscated, and that makes church planting the equivalent of a large print book for the social dynamics that favor charismatic narcissists.

8. ICPC medals for OpenAI and Gemini:

   We received the problems in the exact same PDF form, and the reasoning system selected which answers to submit with no bespoke test-time harness whatsoever. For 11 of the 12 problems, the system’s first answer was correct. For the hardest problem, it succeeded on the 9th submission. Notably, the best human team achieved 11/12.

   We competed with an ensemble of general-purpose reasoning models; we did not train any model specifically for the ICPC. We had both GPT-5 and an experimental reasoning model generating solutions, and the experimental reasoning model selecting which solutions to submit. GPT-5 answered 11 correctly, and the last (and most difficult problem) was solved by the experimental reasoning model.

   and

   An advanced version of Gemini 2.5 Deep Think competed live in a remote online environment following ICPC rules, under the guidance of the competition organizers. It started 10 minutes after the human contestants and correctly solved 10 out of 12 problems, achieving gold-medal level performance under the same five-hour time constraint. See our solutions here.

3. You're Overthinking Packing:

   The amount of planning and thought that needs to go into the enterprise is surprisingly minimal. Count how many days you’re going for, then bring the same number of shirts as the number of days minus one (unless you have access to laundry, then probably less), 2-4 pairs of pants, a couple nicer dresses if that’s your thing and a change of shoes. Something to sleep in at night and a bathing suit if you’re headed somewhere warm. I always bring an extra pair of underwear and socks because sometimes I like to change throughout the day. Then experiment by trying on a bunch items to ensure everything goes together. Frankly, it’s not that different than figuring out what you’re going to wear on a day-to-day basis, which I trust you do all the time.

   Some thinking about packing, maybe some tools (I like using packing cubes and a travel scale is a must when flying budget) are surprisingly useful but yes, the curve drops sharply.

   Seventeen years later, I credit Adderall with enabling me to build a 10x happier, healthier, more virtuous version of myself (to the chagrin of the countless Twitter trolls decrying my “meth addiction” in reply to this recent viral post). Here is my story.

7. LLMs Will be Like Ozempic for Golf:

   Rob was fantastic but it’s not as though I can just do a TrackMan excursion all the time. Yet I remained curious about why my swing was what it was. I had decent power, but lacked the ability to square the ball up with anything approaching consistency. Was I destined to always have this problem?

   And so I turned to LLMs, feeding the TrackMan stats into GPT. Based on 12 numbers, from one swing, GPT had me clocked. It knew my strengths and weaknesses. It fully understood the specifics of my poor technique. I’m sure Rob could have walked me through as much, but his time is limited. The machine had all the bandwidth in the world to deal with my “over the top” swing, how to fix it, and any other questions I might nag it with.

   A day later, my swing was different and self recorded video sent to Google’s Gemini confirmed the change. Swing errors that were decades in the making were corrected in the span of minutes. I’m not saying that I’ve suddenly made a leap from “Struggles to break 100” to “scratch golfer.” I’m just saying that a process that could have been expensive and arduous was instead efficient and relatively cheap. I apply the LLM’s fix, and it tells me whether I’ve actually applied it. The feedback is instant and objective.

   LLMs will be like Ozempic for a lot more than golf. Ability to ask unlimited questions without feeling embarrased or paying by the hour is a big deal. Imagination is the only thing limiting us.

8. GPT-5: The Case of the Missing Agent

   It’s hard to say exactly why, even with all this progress, current AI models are still so hopeless at dealing with open-ended real-world situations. GPT-5’s inability to recognize that it was incapable of playing Minesweeper may indicate that its reasoning abilities do not generalize well. Its decision to spend 5 solid hours beating its head against the unimportant side goal of sharing a spreadsheet suggests a lack of training on the importance of setting priorities. The repeated factual errors in Gemini 2.5 Pro’s writeup of its merch store experience (click the link and look for “Editor’s Notes”) suggest an inability to keep track of key information over an extended project. Claude losing track of the fact that it is not a person is a reminder that in some ways these models really are just shallow imitations of human behavior (even as they demonstrate deep capability in other areas).

   So many benefits and so many limitations.

9. Reading with AI:

   Reading a non-fiction book from cover-to-cover is not efficient. I used to say that I read books “from the outside in.” I look at the book flap to find out about the author, who wrote the blurbs, and the subject matter of the book. Then I read the introduction and conclusion in order to get the main ideas. If I have read something by a different author that seems relevant, I look for that author in the index, and I head to those pages.

   and

   Once again, I believe in “Stop, Look, and Listen.” I start by asking the AI to summarize the key themes of the book. For each theme that the AI lists, I stop and try to put it into my own words. I test my understanding by feeding my words into the AI, in order get confirmation that my interpretation is correct. Another way that I ensure understanding is to suggest possible examples or ask the AI to provide examples.

10. How to think about AI progress: Reproducing the entire post as it really is worth reading:

    The Zvi has a good survey post on what is going on with the actual evidence. I have a more general point to make, which I am drawing from my background in Austrian capital theory.

    There are easy projects, and there are hard projects. You might also say short-term vs. long-term investments.

    The easier, shorter-term projects get done first. For instance, the best LLMs now have near-perfect answers for a wide range of queries. Those answers will not be getting much better, though they may be integrated into different services in higher productivity ways.

    Those improvements will yield an ongoing stream of benefits, but you will not see much incremental progress in the underlying models themselves. Ten years from now, the word “strawberry” still will have three r’s, and the LLMs still will tell us that. There are other questions, such as “what is the meaning of life?” where the AI answers also will not get much better. I do not mean that statement as AI pessimism, rather the answers can only get so good because the question is not ideally specified in the first place.

    Then there are the very difficult concrete problems, such as in the biosciences or with math olympiad problems, and so on. Progress in these areas seems quite steady and I would call it impressive. But it will take quite a few years before that progress is turned into improvements in daily life. Again, that does not have to be AI pessimism. Just look at how we run our clinical trials, or how long the FDA approval process takes for new drugs, or how many people are reluctant to accept beneficial vaccines. I predict that AI will not speed up those processes nearly as much as it ideally might.

    So the AI world before us is rather rapidly being bifurcated into two sectors:

    a) progress already is extreme, and is hard to improve upon, and

    b) progress is ongoing, but will take a long time to be visible to actual users and consumers

    And so people will complain that AI progress is failing us, but mostly they will be wrong. They will be the victim of cognitive error and biases. The reality is that progress is continuing apace, but it swallows up and renders ordinary some of its more visible successes. What is left behind for future progress can be pretty slow.

    Yet another periodic reminder that MR and The Zvi are both must-read for everyone.

   On the porch of the Chilmark General Store and at sunset-watching parties on Menemsha Beach, conversations circle ineluctably to the lone star tick, which after a single bite can leave people with a life-threatening allergy to most meat and dairy.

   Known as alpha-gal syndrome, the condition is changing the way many people shop, cook and eat in a place long known as a food-lover’s retreat for its thriving independent farms and restaurants. These new habits may prove to be lasting, as some islanders who initially avoided beef and cheese temporarily, out of necessity, later give them up for good out of preference.

   Even outside extreme weather events, the lunar cycle moves oceans, huge bodies of water. We are, like all animals, primarily made of water. The word ‘lunacy’ comes from the ancient understanding that our minds can be affected by it

   An interesting experiment is to log your daily mood for a few months- ups and downs, anxiety / joy levels, big arguments with loved ones etc. Then afterwards, retroactively chart it against lunar cycles and NASA space weather data that tracks geomagnetic storms, solar flares etc.

   Be open- minded and try it. I, too, used to think this stuff was BS

   Now I think much of modern psychiatry is giving people drugs to tune down people’s individual responses to these external inputs, eg ‘bipolar’ might just indicate high sensitivity

   How many important scientific breakthroughs lie on the other side of our collective dismissal of ‘woo’?

Adhikari’s team realized that the AI was probably using some esoteric theoretical principles that Russian physicists had identified decades ago to reduce quantum mechanical noise. No one had ever pursued those ideas experimentally. “It takes a lot to think this far outside of the accepted solution,” Adhikari said. “We really needed the AI.”

10. GPT-5 prompting guide:

    GPT-5, our newest flagship model, represents a substantial leap forward in agentic task performance, coding, raw intelligence, and steerability.

    While we trust it will perform excellently “out of the box” across a wide range of domains, in this guide we’ll cover prompting tips to maximize the quality of model outputs, derived from our experience training and applying the model to real-world tasks. We discuss concepts like improving agentic task performance, ensuring instruction adherence, making use of newly API features, and optimizing coding for frontend and software engineering tasks - with key insights into AI code editor Cursor’s prompt tuning work with GPT-5.

    We’ve seen significant gains from applying these best practices and adopting our canonical tools whenever possible, and we hope that this guide, along with the prompt optimizer tool we’ve built, will serve as a launchpad for your use of GPT-5. But, as always, remember that prompting is not a one-size-fits-all exercise - we encourage you to run experiments and iterate on the foundation offered here to find the best solution for your problem.

   If that’s a stumper, here are some followups: Which kind of coffee mug is best? How much does a La Marzocco espresso machine cost? Would you bake your blueberry muffins in-house or would you buy them from a third party?

   The point of the Coffee Beans Procedure is this: if you can’t answer those questions, if you don’t even find them interesting, then you should not open a coffee shop, because this is how you will spend your days as a cafe owner.

9. The Infinite Well: How Innovation Keeps Water Flowing:

   Solutions from experts follow a familiar pattern, claiming that the only way to avert a crisis is to adopt radical social and behavioral changes, driven by moral proselytizing, government intervention, or both, to save the water supply. Environmentalists urge people to replace old toilets with low-flow models, avoid running faucets while brushing their teeth or washing dishes, and switch to eating less water-intensive foods. Meanwhile, activists pressure elected officials to impose usage restrictions, ban certain crops in arid regions, and regulate everything from swimming pools to car washes.

   Fortunately the economics of water innovation reveals why the apparent scarcity tends to be self-correcting, without requiring us to adopt ascetic lifestyles or perform symbolic actions like picking up dropped ice cubes to water house plants or writing letters to elected officials. Rising prices, not moralizing pleas, lead people to conserve, look for substitutes, recycle resources, and innovate helping to meet demand through alternative means or improved efficiency.

   The same principles apply to many other things too.

1. How to Teach Your Kids Poker, the Easy Way:

   The right way to begin is with one-card poker. Everyone antes one chip and gets one card, face down. You look at your card. There’s a single round of betting, which proceeds around the table: If no one else has bet, you can bet or check (do nothing); if anyone in front of you has bet, you can call (or match the bet), raise or fold. When everyone has called the last bet or folded, those who are left in the hand show their card. The highest card wins: Ace is highest, then king, so on down to two.

   That’s it. No pairs, no flushes, no full houses, no complicated order of hands to remember, though you do have to remember that a queen beats a jack. But you learn a lot of poker. You will always win with an ace, but you have to learn to maximize the value of your ace, to induce other people to bet into you and call your raises. One of my proudest moments as a parent was when my daughter first check-raised me with an ace.

   You’ll probably win with a king, but if someone raises you, does that mean that they have an ace (and have you beat), or a queen (and are overconfident), or a six (and are bluffing)? There are 52 cards, so you can estimate the probabilities if you are mathematically inclined, though if you are four you probably won’t.

   You probably won’t win with a six, but if you bet it confidently you might bluff everyone else out. If everyone else checks, and you’re the last person to bet, you might as well bet: You have “position,” everyone else has a weak hand, and you might be able to steal a pot. The essentials are there.

   Once the kids have mastered this, you can introduce the order of hands gently with two-card poker. (Any pair beats a high card, highest pair wins.) Then teach the rest with five-card straight poker. This isn’t a great game, but it’s a brief stopover on the way to five-card draw, which is a perfectly respectable poker game. Texas hold’em is not far behind.

2. My Father's Instant Mashed Potatoes:

   The chuño-chomping Incans were not the last military to rely on dehydrated potatoes for sustenance. In World War II, the US Army experimented with various forms of potato dehydration to help stretch supply lines. The easiest way to get a uniform potato commodity into the hands of G.I.s was to pulverize the potatoes into granules, dehydrate them, and then plan on bringing them back to life with boiling water in an imitation of “mashed potatoes”.

   Deeper than I would have imagined from the title.

3. A lot more than you wanted to read on College and College Admissions. Depressing.

4. The Imitation Game: Defending against AI's Dark Side!:

   A few weeks ago, I started receiving a stream of message about an Instagram post that I was allegedly starring in, where after offering my views on Palantir's valuation, I was soliciting investors to invest with me (or with an investment entity that had ties to me). I was not surprised, since I have lived with imitations for years, but I was bemused, since I don't have an Instagram account and have not posted on Facebook more than once or twice in a decade. In the last few days, those warnings have been joined by others, who have noted that there is now a video that looks and sounds like me, adding to the sales pitch with promises of super-normal returns if they reach out, and presumably send their money in. (Please don't go looking for these scams online, since the very act of clicking on them can expose you to their reach.)

   It was a matter of time.

5. GPT-5: It Just Does Stuff:

   GPT-5 just does stuff, often extraordinary stuff, sometimes weird stuff, sometimes very AI stuff, on its own. And that is what makes it so interesting.

   To be clear this wasn't my experience. I gave it a PDF and asked it to estimate something based on the data in the file. It made up all the numbers and suggested they were in tables and pages that didn't exist in the PDF. I was not able to get it focused on the actual information in the PDF despite multiple reminders and other attempts. Apparently though, there was a bug in their system yesterday that made it appear dumber. I will try again.

1. Philosopher–Builder Summer Reads:

   These aren't generic "tech books." They're works that can shape how serious builders think about what they're creating and why.

   And the original essay.

2. DOGE builds AI tool to cut 50 percent of federal regulations:

   The tool, called the “DOGE AI Deregulation Decision Tool,” is supposed to analyze roughly 200,000 federal regulations to determine which can be eliminated because they are no longer required by law, according to a PowerPoint presentation obtained by The Post that is dated July 1 and outlines DOGE’s plans. Roughly 100,000 of those rules would be deemed worthy of trimming, the PowerPoint estimates — mostly through the automated tool with some staff feedback. The PowerPoint also suggests the AI tool will save the United States trillions of dollars by reducing compliance requirements, slashing the federal budget and unlocking unspecified “external investment.”

   A worthy goal for DOGE and possibly the right use of AI. If done well.

3. America's AI Action Plan Is Pretty Good:

   Otherwise, while this is far from a perfect plan or the plan I would choose, on the substance it is a good plan, a positive plan, with many unexpectedly good plans within it. There is a lot of attention to detail in ways those I’ve asked say reflect people who actually know what they are doing, which was by no means something to be taken for granted. It is hard to imagine that a much better plan could have been approved given who was doing the approving.

   Jim Fan@DrJimFan · Jul 25

   I'm observing a mini Moravec's paradox within robotics: gymnastics that are difficult for humans are much easier for robots than "unsexy" tasks like cooking, cleaning, and assembling. It leads to a cognitive dissonance for people outside the field, "so, robots can parkour & breakdance, but why can't they take care of my dog?" Trust me, I got asked by my parents about this more than you think ...
   
   The "Robot Moravec's paradox" also creates the illusion that physical AI capabilities are way more advanced than they truly are. I'm not singling out Unitree, as it applies widely to all recent acrobatic demos in the industry. Here's a simple test: if you set up a wall in front of the side-flipping robot, it will slam into it at full force and make a spectacle. Because it's just overfitting that single reference motion, without any awareness of the surroundings.
   
   Here's why the paradox exists: it's much easier to train a "blind gymnast" than a robot that sees and manipulates. The former can be solved entirely in simulation and transferred zero-shot to the real world, while the latter demands extremely realistic rendering, contact physics, and messy real-world object dynamics - none of which can be simulated well.
   
   Imagine you can train LLMs not from the internet, but from a purely hand-crafted text console game. Roboticists got lucky. We happen to live in a world where accelerated physics engines are so good that we can get away with impressive acrobatics using literally zero real data. But we haven't yet discovered the same cheat code for general dexterity.
   
   Till then, we'll still get questioned by our confused parents.

5. Two long & good pieces on India this week though I have yet to fully read both.

6. Jhanas and Jhourney:

   So I went down to the beach. "Kinda nice", I thought. The sky had a particularly vibrant blue color, the waves had 'the right size', their roar was pleasant. I started to walk around trying to continue meditating. I focused my awareness on an arising sensation of open heartedness and then I noticed my eyes tearing up ("Huh? I thought"). I looked again at the ocean and then I saw it. It was fucking amazing. So much color and detail: waves within waves, the fractal structure of the foamy crests as they disintegrate back into the ocean. The feeling of the sun on my skin. I felt overwhelmed. As tears ran down my face and lowkey insane grin settled on my face I found myself mumbling "It's... always been like this!!!!" "What the fuck??!" followed by "This is too much!! Too much!!!". The experience seemed to be demanding from me to feel more joy and awe than I was born to feel or something like that. In that precise moment I felt what "painfully beautiful" means for the first time in my life. I had to look away. I calmed a bit. I walked a few steps and looked back. The exact same thing happened. "It's reproducible, hihihihi", and I started laughing. Then I found a log to sit on, calm down, and look back at the ocean. Now it wasn't overwhelming, but "kinda nice" was now "fucking amazing".

   To do list.

7. Yes, Adam Sandler really is a pickup basketball god (NYT Paywall):

   Jackson was struck by the man’s attire: extra-baggy shorts and an extra-baggy yellow T-shirt. “I’m trying to figure out: Does he buy clothes? Did he buy them and then just stop buying them? His clothes really might have been from 2008.” It soon became apparent, however, that the guy could play. He was a true court general. He impressed Jackson with his basketball IQ.

9. Life in deep:

   When her three-person submersible descended more than 30,000 feet into one of the Pacific Ocean’s deepest trenches, Mengran Du wasn’t sure what they would find.

   What she saw, she recalled, was “unbelievable”: Dense clusters of tubeworms with tentacles tinged bloodred, jutting up like skyscrapers. Iridescent snails scaling the worms, like window washers. Bristly, white creatures wriggling between them like rush-hour commuters trying to get home for dinner.

Some readers have commented that I am obsessed with AI. This is not correct. I wish I was. But is there anything more interesting happening in the world right now? I don't think so.

1. Musician Who Died in 2021 Resurrected as Clump of Brain Matter, Now Composing New Music:

   Art can outlast the artist — but what about their artistic impulses?

   A new art installation project in Australia, titled "Revivification," raises this question with a very literal interpretation of "impulse": using his DNA, the team behind the project have performed a quasi-resurrection of the late experimental American composer Alvin Lucier, creating a sort of brain that continuously composes music on the fly with its errant electrical signals.

   At the center of the piece is an "in-vitro brain," grown from blood that Lucier, who passed away in 2021, donated in the final years of his life. Housed in a plinth, it's grown on top of an electrode mesh that connects it to twenty large brass plates placed around the room. Visitors can listen as the brain fires off electrical pulses that trigger a transducer and a mallet behind each plate, striking them to produce sound.

   Is this art? Is this science? Is this composing?

2. Gross(ery) Confusion:

   Teachout’s idea that suppliers “make up the difference” by charging smaller stores more is also economically incoherent. Profit-maximizing firms already charge what the market will bear. If Costco’s volume justifies a discount, that doesn’t mean suppliers can or should charge higher prices to other buyers. Yes, there are models where costs change with volume but costs could go down with volume and, in any case, those models don’t rely on the folk theory of “making up the difference.”

3. AIs and Spontaneous Order:

   This isn’t to say AI won’t help improve economic policy—it might, if we listen. But the future economy won’t look like a centrally planned machine. It will look like an economy of von Neumanns—autonomous agents buying, selling, and strategizing in complex interaction.

4. I Analysed 25,000 Hotel Names and Found Four Surprising Truths:

   And yes, the cat’s out of the bag: there are over 200 Hotels Bristol worldwide, and the reason goes all the way back to an 18th-century English aristocrat whose hotel preferences turned into a naming tradition.

5. I Drank Every Cocktail:

   The International Bartenders Association, or IBA, maintains a list of official cocktails, ones they deem to be “the most requested recipes” at bars all around the world. It’s the closest thing the bartending industry has to a canonical list of cocktails, akin to the American Kennel Club’s registry of dog breeds or a jazz musician’s Real Book of standards. As of 2025, there are 102 IBA official cocktails, and as of July 12, 2025, I’ve had every one of them.

   Legend.

6. How the System Works

   An essay series on the hidden mechanisms that support modern life — and what happens if we don’t maintain them

   This should be amazing. So far, Agriculture, Water and Electricity.

1. The Diaspora Paradox Second in a series from Samir Varma

   But here's the paradox that has haunted me for decades: Why do so many Indians who escape India's constraints become more Indian abroad? Why does the uncle who couldn't be bothered to visit temples in Mumbai suddenly become a founding member of the Hindu temple in New Jersey? Why does the software engineer who rebelled against arranged marriage in Bangalore now insist their American-born daughter marry within the community?

2. The First in 30 Years: Scientists Discover New Class of Antibiotics:

   Led by scientist Gerry Wright, the team has discovered a powerful new molecule called lariocidin. This promising candidate shows the ability to fight some of the toughest, most drug-resistant bacteria known to science. Their groundbreaking findings were published in the journal Nature.

3. Why We’re Surrounding Our Kids with AI:

   We also don’t plan on perpetuating modern Western parents’ egregiously hands-off nature with regard to their kids’ dating and marriage prospects. We already have a going list of agentic, thoughtful, high-achieving families whose kids are close to our kids in age; as our kids get older, we’ll start organizing gatherings for families in this network where our kids can hang out and get to know each other (trips, summer camps, discord servers, study groups, etc.). As our kids reach their late teens and early 20s, we’ll begin organizing modern versions of the London Season—a series of events and gatherings at which our single kids ready for marriage can meet, mix, and get to know each other.

   Did not see this coming.

4. Babies made using three people's DNA are born free of hereditary disease:

   Eight babies have been born in the UK using genetic material from three people to prevent devastating and often fatal conditions, doctors say.

   The method, pioneered by UK scientists, combines the egg and sperm from a mum and dad with a second egg from a donor woman.

5. The Sputnik vs. Deep Seek Moment: The Answers

   I pointed out that the US response to Sputnik was fierce competition. Following Sputnik, we increased funding for education, especially math, science and foreign languages, organizations like ARPA were spun up, federal funding for R&D was increased, immigration rules were loosened, foreign talent was attracted and tariff barriers continued to fall. In contrast, the response to what I called the “DeepSeek” moment has been nearly the opposite. Why did Sputnik spark investment while DeepSeek sparks retrenchment? I examine four explanations from the comments and argue that the rise of zero-sum thinking best fits the data.

6. Reflections on OpenAI:

   I left OpenAI three weeks ago. I had joined the company back in May 2024.

   I wanted to share my reflections because there's a lot of smoke and noise around what OpenAI is doing, but not a lot of first-hand accounts of what the culture of working there actually feels like.
