FOMO, Silence, LLMs & Things Learned

A few of my favorites from an excellent best things learned in 2025 list:

All things being equal, the liquid inside a glass bottle contains more microplastics than the liquid inside a plastic bottle—up to 50X more! This is because plastic-coated metal caps found on glass bottles shed more particles than plastic caps found on plastic bottles.
If you have a son, the chances of your next child being a boy are not 50%, they are actually 57%.
Noise-canceling headphones are causing hearing problems in young people, not because they’re listening with the volume too high, but because blocking ambient noise prevents the brain from learning to filter and process everyday background sound in the real world.
In team sports, women are 13.69 times more likely to be attacked by a fellow teammate than men.
Until very recently, networks didn’t save live television footage because storage costs were too high. The only reason we have access to footage that aired between 1979 and 2012 is because a woman from Philadelphia recorded it and saved it on over 40,000 VHS tapes.
The screens of all laptops in Apple stores are set at an angle of exactly 76 degrees, which is just awkward enough to invite people to tilt them back a bit more, thereby taking the first step toward interacting with the product.
No NFL game has ever ended with a score of 36–23. Across the approximately 17,000 games that have been played in NFL history, this score should have happened 2.68 times by now.
Women are more likely to believe ghosts are real; men are more likely to believe aliens are real.
Coal-burning plants release 100 times as much radiation as nuclear plants per megawatt of power produced.
In 2024, the word “delve” appeared in journal abstracts 28X more frequently than in 2022 because ChatGPT likes the word delve.
The average West Virginian eats more than one hot dog per day.
In Mexico, extending the school day by 3.5 hours led to a 12.6% increase in divorce rates. The extra time made it more likely for women to participate in the labor market, thus increasing their economic independence.
Before 2000, it was common for 10% of Americans to have the same favorite athlete. The 10% threshold was last crossed in 2003, and since 2014, no more than 5% of Americans have had the same favorite athlete. This trend reflects a broader shift away from monocultural sports consumption, where everyone watches the same sports on a few channels, and a shift toward the fragmentation of sports media, where audiences are split across digital platforms and niche interests, preventing any single athlete from dominating the national consciousness.

I conducted dozens of bot challenges based on real things people do with AI, including writing breakup texts and work emails, decoding legal contracts and scientific research, answering tricky research questions, and editing photos and making “art.” Human experts including best-selling authors, reference librarians, a renowned scientist and even a Pulitzer Prize-winning photographer judged the results:

For writing and editing – use Claude
For research and quick answers – use Google’s AI Mode
For working with documents – use Claude
For images – use Google’s Gemini

If I could change one thing about today’s AI tools, I’d make them better at asking follow-up questions that could completely change the answer.

When I asked the chair of the department of medicine at the University of California to judge ChatGPT’s responses to real medical questions he said the difference between a bot with access to infinite knowledge and a good human doctor is that the doctor knows how to answer a question with more questions. That’s how you actually solve someone’s problem.

He suggested an AI strategy I now use regularly: Front-load your queries to a chatbot with as many details as you can think of, knowing that the AI might not stop to ask for some of them before trying to answer. Instead of “summarize this lease,” try “summarize this lease for a renter in D.C., flagging clauses about fees, renewal and early termination.”

Warren Buffett always had lunch at the Stage Deli on Seventh Avenue. A friend pointed out there were many good eateries in New York — why not try someplace new? Buffett replied, “If I like the Stage, why eat somewhere else?” The fear of missing out — responsible for a high percentage of foolish speculations — was unknown to him. This character quirk flowed from a subtle insight: People get in trouble far more often from doing and changing too much rather than doing too little.

Podcasts have devastated my relationship to music, but that is not to say I’ve embraced silence. Whereas I used to listen to music all the time, now I fill every available moment with the sound of people talking.

My change in listening habits comes from a compulsion that many people in my life share: to make every minute of the day as “productive” as possible. By that blinkered calculus, an informative podcast will always trump music. But listening incessantly to podcasts has actually narrowed my interests and shown me just how limiting too much information can be.

I’ve found that trying to make every listening minute count inevitably becomes counterproductive. The internal pressure to optimize free time and always multitask is ultimately exhausting, not enlightening.

The Private Bubble, NFL Scoring & Spam Texts

A few highlights from one of the best articles I’ve read this year discussing the private equity/credit bubble:

The golden age of Private Equity – at least from the standpoint of investor returns (FUM and thus fees to sponsors were significantly lower) – was during 1980-2000, and at a slight stretch, to around the time of the Great Financial Crisis in 2008. During this era, PE delivered legitimately good returns – in some cases outstandingly so. What enabled it was that it was still a niche industry where there was a limited amount of capital chasing deals, while the backdrop was conductive.

In contrast to the 1980-2000s, private equity funds from the 2010s began paying a premium to public market valuations for (typically) small, subscale and illiquid businesses. The problem was that the same thing that always happens when too much money floods into an area happened – bidding competition heated up, target prices rose, and the opportunity that previously existed rapidly disappeared (though the vehicles’ high fee structures of course remained firmly intact). Not surprisingly, since the 2010s, and perhaps as far back as 2006, outcomes have dramatically changed, and PE has delivered generally disappointing returns and underperformed listed equities, and the magnitude of that underperformance has significantly worsened since 2022.

Warren Buffett has scrutinized PEs return calculations and found them to be “well, they’re not calculated in a manner that I would regard as honest.” All kinds of tricks can be and are used to inflate apparent relative returns. PE will often lock up commitments from investors years in advance, and only “call” the funds much later after a deal is done. The IRR calculations only include the period during which the funds are working, but investors need to keep cash in reserve as it can be called at any time, meaningfully diluting effective returns to investors.

The much bigger elephant in the room – the PE industry is currently “marking to model” and is sitting on a vast number of assets it is unable to sell – even in a bull market – because the marks are unrealistic. This will be meaningfully inflating claimed trailing returns, which remain mostly unrealized.

If you look at who private equity companies hire, it is typically ex investment bankers. These guys are deal makers and spreadsheet jockeys, not operational people, and there is no reason to believe they have any unique insights on the intricacies of running small, niche businesses, where specialized skills and decades of domain experience generally count for a lot more than general smarts.

Not to mention that as the industry has mushroomed in size, the average quality of the average hire has meaningfully degraded. Investment bankers also generally lack investment acumen. They are deal makers – a different skill set entirely.

Going even a step further – it’s probable that private equity ownership not only fails to deliver operational improvements, but very likely on net makes the operational performance of companies worse, particularly in the long term. The most obvious means by which this occurs is by saddling investees with significant levels of debt, as well as implementing wholesale asset stripping (such selling and leasing back real estate) and cutting operational costs and capital expenditures to the bone. They frequently don’t just cut the fat, but the muscle as well.

If you are apt to under invest and run the business for maximum cash extraction in the near term, jacking up prices, lowering service quality, squeezing employees, alienating customers and opening the door to competitor inroads – it may improve near term cash generation, but it often comes at the cost of long-term value degradation.

PE has now taken over a large portion of Las Vegas, for instance, and visitors routinely complain of high prices, poor customer service, and the removal of perks such as free drinks that previously endeared visitors to the strip. Visitation has been waning, and people complain Vegas has lost its charm, and has become overpriced and soulless, a victim of “corporate greed.”

This is far from the only example. Employees and customers of PE backed hospitals and dental practices often complain of declining service standards, high prices, and a significant increase in unnecessary treatments unethically prescribed to boost near term utilization/billing.

The fair value of the combined $5 trillion of assets held in the US Private Equity/Credit industry is probably worth only about 60% of that in reality – a $2 trillion hole. When that hole is exposed, it will change economic behavior, and likely to a noticeable degree.

Private Equity/Credit: The Bubble & Its Implications

Great article from Nate Silver this week on reasons why there is more scoring in the NFL:

(1) The number of 55+ yard field goals has increased by 3x since just 2022:

(2) Between longer field goals and the dynamic kickoff, the field has basically been shortened by 10-15 yards.

(3) Quarterback passer ratings are tied for their highest-ever at 93.6:

(4) For the first time in NFL history, quarterbacks as a collective are gaining enough rushing yards to outweigh the yards they lose from sacks:

(5) Analytics have teams successfully attempting and completing fourth down conversions:

(6) Rushing plays on 4th-and-short are being attempted (and succeeding) at extremely high rates. The tush push effect:

If you’ve ever received a spammy text falsely alerting you to an unpaid toll or failed delivery, it might have come from a so-called Phishing-as-a-Service network that Google is now trying to take down. In just 20 days, Google alleges, Lighthouse was used to spin up 200,000 fraudulent websites to attract over a million potential victims. It estimates that somewhere between 12.7 million and 115 million credit cards in the US were compromised by the scam.

In this alleged scheme, the text would link to a spoofed USPS page asking a user to enter their personal and payment details. The page tracks users’ keystrokes, according to the complaint, so the information is compromised even if the user has second thoughts before submitting.

When Will We Make God? The key driver of the AI Bubble:

Hyperscalers (Microsoft, Amazon, Google, Oracle, IBM) believe they might build God within the next few years. That’s one of the main reasons they’re spending billions on AI, soon trillions. They think it will take us just a handful of years to get to AGI—Artificial General Intelligence, the moment when an AI can do nearly all virtual human tasks better than nearly any human.

They think it’s a straight shot from there to super-intelligence—an AI that is so much more intelligent than humans that we can’t even fathom how it thinks. A God. The arguments to claim we’re about to make gods are:

AI expertise is growing inexorably. Threshold after threshold, discipline after discipline, it masters it, and then beats humans at it.
We’re now tackling the PhD level.
In the current trajectory, we should reach AI Researcher levels soon.
Once we do, we can automate AI research and turbo-boost it.
If we do that, super-intelligence should be around the corner.

Chatfishing & Poorly Defined Problems

Why Aren’t Smart People Happier?

A good name for problems on tests that determine someone’s level of intelligence is “well-defined.” Well-defined problems can be very difficult, but they aren’t mystical. You can write down instructions for solving them. And you can put them on a test. In fact, standardized tests items must be well-defined problems, because they require indisputable answers. Matching a word to its synonym, finding the area of a trapezoid, putting pictures in the correct order—all common tasks on IQ tests—are well-defined problems.

People differ in their ability to solve well-defined problems, they’re not the only kind of problems. “Why can’t I find someone to spend my life with?” “Should I be a dentist or a dancer?” and “How do I get my child to stop crying?” are all important but “poorly defined” problems. Getting better at rotating shapes or remembering state capitals is not going to help you solve them.

One way to spot people who are good at solving poorly defined problems is to look for people who feel good about their lives; “how do I live a life I like” is a humdinger of a poorly defined problem. The rules aren’t stable: what makes you happy may make me miserable. The boundaries aren’t clear: literally anything I do could make me more happy or less happy. The problems are not repeatable: what made me happy when I was 21 may not make me happy when I’m 31.

This is why the people who score well on intelligence tests and win lots of chess games are no happier than the people who flunk the tests and lose at chess: well-defined and poorly defined problems require completely different problem-solving skills. Nobody agrees on the rules, the pieces do whatever they want, and the board covers the whole globe, as well as the inside of your head and possibly several metaphysical planes as well.

Over the last generation, we have solved tons of well-defined problems. We eradicated smallpox and polio. We landed on the moon. We built better cars, refrigerators, and televisions. We even got ~15 IQ points smarter. How much did our happiness improve? None.

We haven’t yet defined the problem of “living a happy life”. We know that if you’re starving, lonely, or in pain, you’ll probably get happier if you get food, friends, and relief. After that, the returns diminish very quickly. You could read all the positive psychology you want, take the online version of The Science of Wellbeing, read posts on hacking the hedonic treadmill, meditate, exercise, and keep a gratitude journal—and after all that, maybe you’ll be a smidge happier. Whatever else you think will put a big, permanent smile on your face, you’re probably wrong.

We fawn over people who are good at solving well-defined problems. They get to be called “professor” and “doctor.” We pay them lots of money to teach us stuff. They get to join exclusive clubs like Mensa and the Prometheus Society.

People who are good at solving poorly defined problems don’t get the same kind of kudos. They don’t get any special titles or clubs. There is no test they can take that will spit out a big, honking number that will make everybody respect them.

And that’s a shame. My grandma does not know how to use the “input” button on her TV’s remote control, but she does know how to raise a family full of good people who love each other, how to carry on through a tragedy, and how to make the perfect pumpkin pie.

If you don’t value the ability to solve poorly defined problems, you’ll never get more of it. You won’t seek out people who have that ability and try to learn from them, nor will you listen to them when they have something important to say. You’ll spend your whole life trying to solve problems with cleverness when what you really need is wisdom. And you’ll wonder why it never really seems to work. All of your optimizing, your straining to achieve and advance, your ruthless crusade to eliminate all of the well-defined problems from your life—it doesn’t actually seem make your life any better.

‘I realized I’d been ChatGPT-ed into bed’: how ‘Chatfishing’ made finding love on dating apps even weirder.

Standing outside the pub, 36-year-old business owner Rachel took a final tug on her vape and steeled herself to meet the man she’d spent the last three weeks opening up to. They’d matched on the dating app Hinge and built a rapport that quickly became something deeper. “From the beginning he was asking very open-ended questions, and that felt refreshing,” says Rachel.

One early message from her match read: “I’ve been reading a bit about attachment styles lately, it’s helped me to understand myself better – and the type of partner I should be looking for. Have you ever looked at yours? Do you know your attachment style?” “It was like he was genuinely trying to get to know me on a deeper level. The questions felt a lot more thoughtful than the usual, ‘How’s your day going?’” she says.

Soon, Rachel and her match were speaking daily, their conversations running the gamut from the ridiculous (favourite memes, ketchup v mayonnaise) to the sublime (expectations in love, childhood traumas). Often they’d have late-night exchanges that left her staring at her phone long after she should have been asleep. “They were like things that you read in self-help books – really personal conversations about who we are and what we want for our lives,” she says.

Which is why the man who greeted her inside the pub – polite, pleasant but oddly flat – felt like a stranger. Gone was the quickfire wit and playful rhythm she’d come to expect from their exchanges. Over pints he stumbled through small talk, checked his phone a little too often, and seemed to wilt under the pressure of her questions. “I felt like I was sitting opposite someone I’d never even spoken to,” she says. “I tried to have the same sort of conversation as we’d been having online, but it was like, ‘Knock, knock, is anyone home?’ – like he knew basically nothing about me. That’s when I suspected he’d been using AI.”

Rachel gave her date the benefit of the doubt. “I thought maybe he was nervous,” she says. But she’d been “Chatfished” before, so when the gap between his real and digital selves failed to close on their second date, she called it off. “I’d already been ChatGPT-ed into bed at least once. I didn’t want it to happen again.”

In a landscape where text-based communication plays an outsized role in the search for love, it’s perhaps understandable that some of us reach for AI’s helping hand – not everyone gives good text. Some Chatfishers, though, go to greater extremes, outsourcing entire conversations to ChatGPT, leaving their match in a dystopian hall of mirrors: believing they’re building a genuine connection with another human being when in reality they’re opening up to an algorithm trained to reflect their desires back to them.

Youtube is eating everything:

Offshoring Automation & Meaningful Ordinary Things

Inside a multistory office building in Manila’s financial district, around 60 young men and women monitored and controlled artificial intelligence robots restocking convenience store shelves in distant Japan. Occasionally, when a bot dropped a can, someone would don a virtual-reality headset and use joysticks to help recover it.

The AI robots are designed by Tokyo-based startup Telexistence, and run on Nvidia and Microsoft platforms. Since 2022, the company has deployed the machines in the back rooms of over 300 FamilyMart and Lawson stores in Tokyo. It is also planning to use them soon in 7-Elevens.

The bots are remotely monitored 24/7 in Manila by the employees of Astro Robotics, a robot-workforce startup. Japan faces a worker shortage as its population ages, and the country has been cautious about expanding immigration. Telexistence’s bots offer a workaround, allowing physical labor to be offshored. This lowers costs for companies and increases their scale of operations, he said.

It’s hard to find workers to do stacking in Japan. If you get one who’s willing to do it, it’s going to be very expensive. The minimum wage is quite expensive. It’s easy to get young, tech-savvy Filipinos to operate the robots. Each tele-operator, called a “pilot,” monitors around 50 robots at a time.

The bots are usually autonomous, but occasionally — about 4% of the time — they mess up. Perhaps they drop a bottle, which rolls away. Getting the AI bot to recover it by mimicking the human grip perfectly — the friction, the feel of metal in the hand — is one of the more challenging problems in robotics. That’s when a pilot steps in.

Astro Robotics’ tele-operators are benefiting from an AI- and automation-related boom in IT-service work and tech jobs in the Philippines, even as layoffs hit similar workers in richer countries. Filipino tech workers maneuver industrial robots, drive autonomous vehicles, collaborate with AI on various tasks, or help build “AI agents,” which are computer programs that enable autonomous action.

Diane has been a death doula for two decades now, meaning she is a companion for people at the end of life. She has sat beside people with no time left to waste and nothing left to prove, continually learning from the profound insights they leave behind. An insight she has gleaned:

What does it really mean to live like you are dying? Go skydiving? Ride a bull? Those may sound fun, but insights from people who are actually dying are often simpler and much deeper.

One client told me, “I just want to sit in my own kitchen one more time, with the people I love and a bowl of warm, fresh pasta with parmesan cheese melting on top.” That was his dream. Not a trip to Bali. Not bungee jumping. Just warm pasta, family, and home.

I used to expect that people would reminisce about big events like weddings, awards, or epic vacations. But over and over, what they actually longed for were the simplest pleasures.

My client Bernice had lived an extravagant life. Her walls were covered with perfectly posed photographs of big events from her life. But in her final months, she said, “I wish I had different pictures on the wall—messy ones. Pajama parties with friends, Sunday night movies with my kids, and neighborhood barbeques.” Those were the memories that stirred her soul.

We spend so much of life chasing big moments, but the dying often remind me that it’s not the grand gestures that matter most in the end. It’s the small, ordinary things. A meaningful life is built in everyday moments. Not in the highlight reel, but in the quiet, ordinary spaces in-between.

The dying know something we seem to have forgotten: Life is happening right now. In the warm pasta. During the neighborhood barbecue. In the sound of your favorite voice calling your name. Big events are wonderful, but in the end, the ordinary is everything.

The decline of local news has all kinds of implications. One that doesn’t get much attention is that the wider the news becomes, the more likely it is to be pessimistic. Two things make that so:

Bad news gets more attention than good news because pessimism is seductive and feels more urgent than optimism.
The odds of a bad news story—a fraud, a corruption, a disaster—occurring in your local town at any given moment is low. When you expand your attention nationally, the odds increase. When they expand globally, the odds of something terrible happening in any given moment are 100 percent.

The top 10 stocks in the S&P 500 account for 40% of the index’s market cap. Since ChatGPT launched in November 2022, AI-related stocks have registered 75% of S&P 500 returns, 80% of earnings growth, and 90% of capital spending growth. Meanwhile, AI investments accounted for nearly 92% of the U.S. GDP growth this year. Without those AI investments growth would be flat. America is now one big bet on AI, and this concentration creates fragility.

Valuations for the Mag 10 — the original group of seven leading tech stocks, plus AMD, Broadcom, and Palantir — are high, but not yet at historic peaks. The 24-month forward P/E ratio of the Mag 10 is 35x. In 2000, at the height of the dot-com bubble, the top 10 stocks traded at 52x forward earnings. Implicit in these valuations, however, is an assumption that AI will help these companies cut costs, or grow revenues by $1 trillion in the next two years. I believe we’re either going to see a massive destruction in valuations, infecting all U.S. stocks and global markets. Or we’re going to see a massive destruction in employment across industries with the highest concentrations of white-collar workers. Both scenarios are ugly.

Cellphone bans in schools have become a popular policy in recent years in the United States, yet very little is known about their effects on student outcomes. In this study, we try to fill this gap by examining the causal effects of bans using detailed student-level data from Florida and a quasi-experimental research strategy relying upon differences in pre-ban cellphone use by students. Several important findings emerge.

The enforcement of cellphone bans in schools led to a significant increase in student suspensions in the short-term, but disciplinary actions began to dissipate after the first year, potentially suggesting a new steady state after an initial adjustment period.
We find significant improvements in student test scores in the second year of the ban after that initial adjustment period.
The findings suggest that cellphone bans in schools significantly reduce student unexcused absences, an effect that may explain a large fraction of the test score gains.

Contentment, Luck, Knowledge & Experience

When we dream about being happier in the future, we’re imagining being content with what we have. Maybe we picture a new house or a luxurious lifestyle. But what we’re really imagining is being satisfied with those things. We’re not just picturing wealth, you’re picturing contentment. But often, when reality doesn’t live up to expectations, it’s because the moment we get something new, we immediately start wanting whatever comes next.

The more you desire something you don’t have, the more you’re just focusing on the fact that you’re not happy right now. The person who has everything but wants even more feels poorer than the person who has little but wants nothing else.

______________________

In economics, there is something called the law of diminishing marginal utility. Simply put, it states that for any commodity, you will derive lower levels of utility (or pleasure) with each additional unit you consume. For example, if you’re hungry and you buy a burger, that first one will be amazing. But if you buy another burger, then that one will be less pleasurable than the first. And by the 5th burger, you’ll hate yourself and won’t buy that burger again for the next month (at least).

When it comes to overcoming obstacles, however, I feel that there’s an inverse of this: a law of increasing marginal utility. With each obstacle you overcome, the utility comes in the form of a lesson you can import into the next obstacle you face. And once you overcome that one, the utility gained has a compounding effect that takes all the prior lessons into account as well.

This has the interesting effect of allowing calmness to be more of a baseline state as you’re introduced to various obstacles over time, one of the benefits of getting older.

___________________________

A group of researchers piggybacked on the Global Flourishing Survey, which asked more than 200,000 people in 22 countries over five years to rate how they feel about several aspects of life. One item was the question: “In general. How often do you feel you are at peace with your thoughts and feelings?”

The older people get, the more they feel inner peace. The pattern that emerges is the one that people who no longer compete with other people (whether it is for a job, a salary increase, a spouse, etc.) simply are happier.

_____________________________

Knowledge of the world (through screens and images) vs. experiencing the world in-person:

“It feels as if the whole world has been transformed into images of the world, and has thus been drawn into the human realm, which now encompasses everything. There is no place, no thing, no person or phenomenon that I cannot obtain as image or information. One might think this adds substance to the world, since one knows more about it, not less, but the opposite is true: it empties the world, it becomes thinner. That’s because knowledge of the world and experience of the world are two fundamentally different things. While knowledge has no particular time or place and can be transmitted, experience is tied to a specific time and place and can never be repeated. For the same reason, it also can’t be predicted. Exactly those two dimensions – the unrepeatable and the unpredictable – are what technology abolishes. The feeling is one of loss of the world.”

Apart from anything else, another good reason to get outside, and soon.

We are told to view winning, in sport and in life as: “success must be earned by an effort of willpower, preferably in a triumph over adversity.”

Natural talent conflicts with the consoling fantasy that we live in a meritocracy where hard work always pays off in the end. But it doesn’t. We simply never hear about the thousands of would-be athletes (or business people, or musicians, or inventors) who put in their 10,000 hours but lack the talent to make significant progress.

If people believe, as more and more of them are encouraged to, that their advancement comes 100% from their own merits . . . they can be insufferably smug. Recognizing luck as a factor in success is inherently civilizing.

It can be difficult to accept that we are all, to some degree, victims and beneficiaries of circumstance, but we are. We are misled by histories of great men and women in which it’s implied that each planned his or her ascent meticulously, homing in on success like a soldier finding a flag in an army training exercise.

The origins of success are usually much more subtle and complex. Successful people, by being open to opportunity and exposing themselves to chance, take new directions that prove more fruitful than anyone could have predicted. We change in many ways as we grow. A missed opportunity represents the failure to evolve into a different, better person.

Believing in luck does not imply fatalism, as many people mistakenly believe. But it does demand openness—and humility. What about effort, skill and planning? All necessary, of course—but never sufficient.

AI may produce faster and more extensive searches and may find correlations that human efforts could not identify in a lifetime, but that’s all still existing information. In short, AI has no creative capacity. It cannot “think” of anything new, unlike humans who create new formulas and works of art routinely. AI is not “intelligent” or creative. It’s just fast.

In a recent experiment, a supercomputer and a group of first grade children were given a ruler, a teapot and a stove and asked to draw a circle. The computer “knew” that the ruler was a draftsman’s tool not unlike a compass and promptly tried to draw a circle with a ruler. It failed. The children glanced at the teapot, saw that the bottom was round and used it to trace perfect circles.

AI will never be superintelligent, expenditures have hit the wall of diminishing returns, AI offers no creativity at all (just fast searches), and children can outperform the fastest machines when the task calls for intuition. Is the frenzy about to hit the wall?

There are some encouraging solutions that may allow AI to add value beyond robotics and fast processing. One of these is the use of small language models (SLMs) instead of LLMs.

Unlike LLMs, which troll the entire internet or large subsets, SLMs contain far less data and are curated by subject matter experts to be tailored to specific tasks. One difference between SLMs and LLMs is the number of parameters that the model is trained on. SLMs can run faster on far less energy. They can also be scaled more easily for smart phones and other applications like self-driving cars and household appliances.

SLMs also have fewer “hallucinations” than LLMs and run on less expensive chips, which may have negative implications for monster chip makers like NVIDIA. SLMs running on smaller cloud systems may make the massive server farms now being constructed, either redundant or obsolete.

Time, Work, Beer & A.I.

Does Time Seem To Be Flying By? There Are Ways To Slow It Down. Exposure to variety in your life creates memories, which in turn makes time seem to pass slower because there is more to look back on. For children, fresh experiences and “firsts” are a natural part of everyday life — losing that first tooth, first day of school, first bicycle. This constant stream of new occurrences stretches the passage of time in a young mind.

Older adults, on the other hand, often slip into predictable patterns where days differ only by the calendar date. With scant new memories being formed between existing time markers like birthdays and holidays, Christmas seems to roll around quicker each year.

So as simple as it sounds, if you want time to slow down, the key is to intentionally introduce more novel experiences into your daily routine. Researchers divide these into two categories:

Distinct novelty. Taking a trip to somewhere you have never been fires a whole different system in your mind that preserves all the details like a high-resolution photo, creating vivid memories you recall for years to come. Your brain’s reaction is, “This looks important. I’d better save all of this!”

Common novelty. You decide to try a different restaurant in your neighborhood instead of the ones you normally frequent. It’s new but related to something you already know, so the impression is not particularly powerful.

Typically, what you find in highly successful people is that an addiction to work is, in fact, based on an inchoate belief that love from others—including spouses, parents, and friends—can be earned only through constant toil and exceptional merit.

Why might someone fall prey to such an erroneous belief? It could be the way you were raised. Workaholic parents tend to have workaholic kids. If you grow up seeing adulthood modeled by people who work all hours and are rarely home, you can be forgiven for regarding this as appropriate behavior for a responsible spouse and parent. This is at least partly the same mechanism behind the fact that you are much likelier to become an alcoholic if you were raised by one.

Researchers have also shown that when parents express love for a child in a conditional way based on the child’s behavior, that person is likely to grow up feeling that they deserve love only through good conduct and hard work. This might sound as though I’m describing terrible parents, but I don’t mean to do so at all; well-intentioned parental encouragement can be heard by a child as a message about their worthiness.

In the workaholic’s case, it might look like this: Your parents wanted you to succeed in school and in life, so they gave you the most love and attention when you got good report cards, won at sports, or earned the top spot in the orchestra. You were a bright kid, and put two and two together: I am extra lovable when I earn accolades. In my experience, this describes the childhood of a lot of people who strove to be special to gain their parents’ attention, and who carry this behavior into adulthood by trying to earn the love of others through compulsive work.

Michelob Ultra has become king of the hill among beer brands. By topping the sales by volume charts for 2025, it has ousted Modelo Especial as America’s best-selling beer.

While its lower caloric content certainly appealed to many people, some of Michelob Ultra’s success can also be credited to aggressive marketing campaigns, which helped the brand gain notoriety at major sporting events like the FIFA Club World Cup, NBA games, and the PGA tour. That falls in line with Michelob Ultra’s focus on folks with active lifestyles.

More people are seeing Michelob Ultra on tap. The new top dog surpassed its sister brand, Bud Light, in bar and restaurant presence in December 2024. Michelob Ultra’s upsurge in popularity happened at a relatively quick pace; the brand has flourished by 15% since 2020. That equates to a 2% hold over the entire beer market in that time frame.

A.I. investors shouldn’t swim upstream, but fish downstream: companies whose products rely on achieving high-quality results from somewhat ambiguous information will see increased productivity and higher profits. These sectors include professional services, healthcare, education, financial services, and creative services, which together account for between a third and a half of global GDP and have not seen much increased productivity from automation. AI can help lower costs, but how individual businesses incorporate lower costs into their strategies—and what they decide to do with the savings—will determine success. To put it bluntly, using cost savings to increase profits rather than grow revenue is a loser’s game. The companies that will benefit most rapidly are those whose strategies are already conditional on lowering costs.

With A.I., knowledge-intensive services will get cheaper, allowing consumers to buy more of them, while services that require person-to-person interaction will get more expensive, taking up a greater percentage of household spending. This points to obvious opportunities in both. But the big news is that most of the new value created by AI will be captured by consumers, who should see a wider variety of knowledge-intensive goods at reasonable prices, and wider and more affordable access to services like medical care, education, and advice.

There is nothing better than the beginning of a new wave, when the opportunities to envision, invent, and build world-changing companies leads to money, fame, and glory. But there is nothing more dangerous for investors and entrepreneurs than wishful thinking. The lessons learned from investing in tech over the last 50 years are not the right ones to apply now. The way to invest in AI is to think through the implications of knowledge workers becoming more efficient, to imagine what markets this efficiency unlocks, and to invest in those. For decades, the way to make money was to bet on what the new thing was. Now, you have to bet on the opportunities it opens up.

There is a consistent doom-and-gloom forecast that within 18 months A.I. software will make human capabilities worthless. The far more significant crisis is precisely the opposite. Young people are already degrading their cognitive capabilities by outsourcing their minds to machines long before software is ready to steal their jobs.

Many recent articles have loudly proclaimed what most people were already thinking: Everybody is using AI to cheat their way through school. By allowing high school and college students to summon into existence any essay on any topic, large language models have created an existential crisis for teachers trying to evaluate their students’ ability to actually write, as opposed to their ability to prompt an LLM to do all their homework. Massive numbers of students are going to emerge from university with degrees, and into the workforce, who are essentially illiterate.

The demise of writing matters, because writing is not a second thing that happens after thinking. The act of writing is an act of thinking. Students, scientists, and anyone else who lets AI do the writing for them will find their screens full of words and their minds emptied of thought.

As writing skills have declined, reading has declined even more. Most of our students are functionally illiterate. Achievement scores in literacy and numeracy are declining across the West for the first time in decades.

Americans are reading words all the time: email, texts, social media newsfeeds, subtitles on Netflix shows. But these words live in fragments that hardly require any kind of sustained focus; and, indeed, Americans in the digital age don’t seem interested in, or capable of, sitting with anything linguistically weightier than a tweet. The share of Americans overall who say they read books for leisure has declined by nearly 50 percent since the 2000s.

Even America’s smartest teenagers have essentially stopped reading anything longer than a paragraph. Students are matriculating into America’s most elite colleges without having ever read a full book. High schools have chunkified books to prepare students for the reading-comprehension sections of standardized exams.

Thinking benefits from a principle of “time under tension.” It is the ability to sit patiently with a group of barely connected or disconnected ideas that allows a thinker to braid them together into something that is combinatorially new.

A.I. related stocks have accounted for 75% of S&P 500 returns, 80% of earnings growth and 90% of capital spending growth since ChatGPT launched in November 2022. Data centers are eclipsing office construction spending and are coming under increased scrutiny for their impact on power grids and rising electricity prices.

The biggest medium-term risk I can think of for top heavy US equity markets: China’s Huawei and SMIC pierce the $6.3 trillion NVIDIA-TSMC-ASML moat by creating their own supernode computing clusters and deep-ultraviolet lithography machines of comparable quality.

Oracle’s stock jumped by 25% after being promised $60 billion a year from OpenAI, an amount of money OpenAI doesn’t earn yet, to provide cloud computing facilities that Oracle hasn’t built yet, and which will require 4.5 GW of power (the equivalent of 2.25 Hoover Dams or four nuclear plants), as well as increased borrowing by Oracle whose debt to equity ratio is already 500%. In other words, the tech capital cycle may be about to change.

This is a fascinating look at how foreign households invest. I had no idea U.K. residents had such a low percentage of their personal investments in stocks, and the amount Japanese citizens hold in cash (which has provided no interest/return for decades) is incredible.

Money, Happiness & Cancer

William Vanderbilt was the son of the great Cornelius Vanderbilt. When his father died, Cornelius was the richest person on the planet. Billy took his father’s wealth and almost immediately doubled it with some shrewd business maneuvers (in today’s terms, imagine Elon Musk’s son inheriting $500 billion when he dies and then investing it and quickly doubling it to $1 trillion). Being the richest rich person didn’t make William Vanderbilt any happier:

“The sheer magnitude of his fortune, he told Chauncey Depew, gave him no advantages over men of moderate wealth. “I have my house, my pictures and my horses, and so do they. I can have a steam yacht if I want to, but it would give me no pleasure, and I don’t care for it.” On another occasion he spoke of a neighbor saying, “He isn’t worth a hundredth part as much as I am, but he has more of the real pleasures of life than I have. His house is as comfortable as mine, even if it didn’t cost so much; his team is about as good as mine; his opera box is next to mine; his health is better than mine, and he will probably outlive me. And he can trust his friends.”

Being the richest person in the world brought him, he said, nothing but anxiety.

The founder of MVMT recently sold his company for $100 million at age 29. He recently posted on Reddit how two years after selling his company he’s lonelier than ever and deeply depressed. Money dramatically improves everyone’s lives up until the point they can relax and be content. After that, assuming they are in moderately good health, almost all happiness comes internally.

The largest medical A.I. randomized controlled trial yet performed, enrolling >100,000 women undergoing mammography screening, was published today. The use of A.I. led to 29% higher detection of cancer, no increase of false positives, and reduced workload compared with radiologists without A.I.

The Drug Industry Is Having Its Own DeepSeek Moment. It isn’t just artificial intelligence—Chinese biotechs are now developing drugs faster and cheaper than their U.S. counterparts. Many top scientists trained in the U.S. have returned to China over the past decade, fueling the emergence of biotech hubs around Shanghai. And just as DeepSeek built a formidable chatbot—allegedly on a lean budget with limited access to semiconductors—Chinese biotech companies are also scrappier, capitalizing on a highly skilled, lower-cost workforce that can move faster. Additionally, companies can conduct clinical trials at a fraction of what they would cost in the U.S., while recent changes in the Chinese regulatory system have streamlined and accelerated the approval process to get a study started.

A new study by Stanford University researchers finds that the average online sportsbook customer expects a gain of 0.3 cent for every dollar wagered. In reality, sports bettors lose an average of 7.5 cents per dollar wagered, reflecting widespread overoptimism about financial returns. We found that people more or less understood the amount of money they had lost in the past, but they just thought the future would be better. Parlay bettors do so much worse than single-outcome bettors and are so much more overconfident in their chances that they likely account for most of the excessive optimism in the overall sample.

European stocks have under-performed U.S. stocks in 12 of the last 15 years. However, the pedestrian pace of the European economy and markets could be a virtue for investors in the years ahead. Europe suffers from none of the over-building excesses that haunt the Chinese economy. European equity markets have none of the bubbly valuations that pose a threat to U.S. stocks. A starting point of a weak euro and monetary easing, combined with a high savings rate and fiscal capacity has the potential to boost both economic growth and dollar-denominated returns on European equities. Attractive dividend yields can allow European equities play a respectable role in generating income. Moreover, political pressure from within Europe, along with the threat of tariffs from the United States, could motivate bolder action from European policymakers in both deregulation and fiscal stimulus, triggering greater economic momentum. The strongest case for European equities is simply a value case. At the end of January, the MSCI Europe ex-UK had a forward P/E of 14.7 times compared to 21.8 times for the S&P500, a discount that is more than two standard deviations greater than its average over the past 20 years. It also sported a dividend yield of 3.3% compared to 1.3% for the S&P500.

The silver market is heading into a perfect storm. Even in our most conservative case, holding everything but solar demand constant, we’re looking at potential deficits of 100-200 million ounces annually for the next decade. Solar panels now consume one in four ounces of silver mined globally. Even at current solar installation rates – before factoring in any AI-driven surge in energy demand – we’re looking at a supply-demand gap as large as the entire elastic (price-sensitive) portion of silver supply. Solar demand is structurally inelastic – panel manufacturers will buy silver at almost any price because it represents a tiny fraction of total costs but is essential to functionality. The sheer scale of the energy transition dwarfs anything in silver’s industrial history – we’re talking about rebuilding the entire global energy infrastructure.
