1. There is massive synaptic pruning between birth and adulthood.
2. Some major city populations from 1854.
3. From Samuel Hammond: “The AI boom is doubly upsetting to progressive economic commentators because it a) shows “financialization” was largely a macro story that eventually solved itself, and b) the boom is being driven by AI rather than their hoped-for “green transition”.” Plus it shows the internet and social media really were worth it, and that many tech companies are run by geniuses not superficial idiots.
4. The safety of mRNA vaccines.
5. Do the optimistic live longer?
6. How many people have ever lived in the United States? And what percentage of them are living here now?
7. What is going on with SpudCell? (NYT).
Rent Control: The Ceiling Trap
Rent control is in the news again. Check out my new website, Rent Control: The Ceiling Trap. Here is just one bit:
Norway abolished its rent control in 1982, and the economist Are Oust realized the newspapers had been quietly recording the whole experiment. He collected housing classifieds from Oslo’s Aftenposten from 1970 to 2008 and watched the market turn inside out.
Under rent control, Oslo’s listings pages looked nothing like a housing market. It was tenants who advertised, pleading their qualities to landlords — “housing wanted” ads outnumbered “housing for rent.” Ten to fifteen percent of those ads were placed by the tenant’s employer, vouching for them the way a bank vouches for a borrower. Tenants offered babysitting, gardening, snow-shoveling, and janitorial work on the side to sweeten the deal. Landlords, for their part, could demand a tenant of a particular gender, age, occupation, region of origin — some ads specified “strong Christian beliefs.” Deposits commonly ran to 50 or 60 months’ rent, occasionally 100 or more: tenants effectively lent the landlord the equity of the flat, interest free. And only about 20 percent of “for rent” ads dared print the rent, much of which would have been illegal.
Then the ceiling lifted. Within a few years the page flipped: landlords advertised to tenants, roughly 80 percent of listings printed an asking rent, the mega-deposits vanished, and the demands for snow-shoveling Christians of specified gender dwindled to nothing. The price went back to doing the rationing — so nothing else had to.
Check out the whole thing–it’s fabulous.
Is Alexander Calder the great American artist?
I am not ready to make this claim, but I wondered this after seeing the marvelous exhibit at Fondation Vuitton. To Calder’s credit:
1. His work is both beautiful and deep. It also can be fun. Unlike many other high-status artists, most Americans like or could like his work.
2. It is immediately recognizable and the body of work has a coherence as a whole.
3. He invented a new form — the mobile — and showed it could be art.
4. His works have iconic placement in many major American cities, namely Chicago, Grand Rapids, New York, Los Angeles, Cambridge, Philadelphia, Houston, Minneapolis, Seattle, and a bunch more. Who else can match that list?
5. He worked in multiple genres with great success, including not just sculpture (of various kinds, including wire sculpture and bronze sculpture) but also painting, works on paper, and jewelry (!). He worked with metal and wood and wire and string in his sculptures. The exhibit is wonderful in showing all this.
6. He built things, a very American endeavor, and he trained as a mechanical engineer. Mobility is also a very American idea.
7. He lived during the major period of American growth and hegemony, namely 1898-1976, very American years to have been on the scene.
I would note that most people think first of his large installations, which to me are his least interesting works. The small sculptures I admire the most? In this regard he remains underrated.
Who else are possible candidates for this designation? A while back Jasper Johns might have been an obvious leader for the title, and he remains in contention. But perhaps it is all a tad too formal and serious?
Rothko and Pollock are too one-dimensional, no matter how much you may admire the dimension. The Hudson River School does not boil down easily enough to a single artist, plus it is mainly just painting. Winslow Homer is a possibility. Warhol is another candidate, as his work is both seminal and “very American,” but currently it feels overexposed? (I am not anti-Warhol but perhaps his influence peaked some while ago.) Roy Lichtenstein did very well in sculpture as well as painting and prints, and he is in the running as well.
But I no longer think Calder is such a crazy choice for this designation. Do go see the show! The people we saw the show with were amazed at how much they had underrated his depth, breadth, and quality.

How to ask for help from a stranger
The next heuristic is to make your request easy to accept. Making something easy to accept largely is about reducing the cost of acceptance. One clear kind of cost is the magnitude. Do ask someone for twenty minutes of their time, but don’t ask them to read your five-hundred-page manuscript in a week. Another is to make it specific: asking for a resource to start with is better than “can I pick your brain?”. When you’ve made your request, make it low friction for them. If you’re asking for an introduction, write a blurb about yourself which they can forward. If you have a question, ask it in writing rather than over a call. And last on cost, make your ask bounded. Don’t ask for recurring obligations like being your mentor for your whole life, but do keep it limited to asking them to read a blog post. If that instance goes well, they’ll gladly read more.
My last heuristic is stranger: make it easy to say no. You might think that the worst outcome is a no, but the worst outcome is a pressured, begrudging yes. Your coercion will have poisoned your relationship with this person while you feel the false glow of a hard-won victory. A person who helps you with gritted teeth is one who will never help you again. And even then, the help will be a half-hearted effort to get rid of the obligation you manufactured. By contrast, help freely given is effortless, the way you’d hold the door open for someone. Help willingly given keeps your conscience clear, free from the burden of having pressured someone. And help, when given from the heart, is the foundation of a relationship where both of you contribute to what you’re building.

Civilian supersonic flights are being legalized in the U.S.
For too long, outdated rules based on old technology held back American aerospace innovation. Now, we are updating those rules for the first time since the 1970s. Today @USDOT announced a new proposal to enable civil supersonic flight by replacing speed limits with noise limits, ushering in a new era of safer, quieter, and faster air travel for all Americans.
That is from Michael Kratsios. Here is how the 1973 ban first came about. More details will be forthcoming, here is one concern from Eli.
Fables of the Reconstruction/Reconstruction of the Fables
What I’ve been reading
1. Elizabeth Buchanan, So You Want to Own Greenland? A useful and dispassionate overview of the relevant history and issues. The author is from Australia. I had not known that Norway unilaterally claimed parts of eastern Greenland in the early 1930s, though gave it back to Denmark following a Hague adjudication and ruling.
2. Andrea Wulf, The Traveler: One Man’s Epic Quest for Discover Our Shared Humanity. This book meets her usual high standards. In this case the traveler is George Foster, who sailed with Cook to the South Seas and had relatively sympathetic attitudes toward the indigenous peoples there.
3. James Hawes, The Shortest History of Ireland. From a useful series, even if some of the claims are wrong and the judgments intemperate. Such books force you to think through your own views and interpretations, they serve as refreshers for the basic history, and they do give you conceptual frameworks of a sort. You are more likely to remember the core histories when you read books like this, but caution typically is in order as well.
4. Simon Warrack, Monumental: Great Buildings of the World Through the Hands and Eyes of a Stonemason. An engaging book about the beauties of stonemasonry, with case studies of Venice, Angkor Wat, Lalibela, Zimbabwe and other locales.
5. Roger Zelazny, Lord of Light. Yup. “Earth is long since dead. On a colony planet, a band of men has gained control of technology, made themselves immortal, and now rule their world as gods of the Hindu pantheon.” First published in 1967.
Differentiation drives the erosion of positivity on social media
We live in a digital age, where billions of people engage in dialogue within topic-bound communities and threads. In an archival analysis of over 2 billion Reddit comments and an experiment, we show that this dialogue becomes more negative over time. Further analyses suggest that negativity rises over time because social media users seek to make unique comments on the same topic, and it is easier to differentiate oneself through negative comments than through positive comments. As threads and communities evolve, and it becomes more difficult to make unique observations, users turn to negativity. Our studies show how basic human motives interact with the structure of social media platforms, posing an acute challenge for sustaining healthy online dialogue.
Here is the article by Hongkai Mao, et.al. Via the excellent Kevin Lewis. For some of you commenters, how does it feel to be a puppet in the unfolding of this game?

What should I ask Daron Acemoglu?
Yes, I will be doing a Conversation with him. Obviously Acemoglu has published plenty, but likely this chat will focus on his recent writings and pronouncements on AI, and most of all his forthcoming book What Happened to Liberal Democracy? Remaking a Politics of Shared Prosperity. So what should I ask him?
Prediction markets paragraphs to ponder
The oracle is an elaborate Web 3.0 contraption that combines cryptocurrency, voting and game theory in its goal to produce fair judgments. It’s billed by its creators, a company based in Manhattan called Risk Labs, as a “decentralized truth machine.”
But for all its brainiac complexity, the oracle has proved exploitable. Dozens of livid bettors claim the system has been gamed, the handiwork of a budding tech entrepreneur named Lancelot Chardonnet (his name at birth, he says). A look at the Donk debate, which unfolded over nine rancorous days, illustrates how he did it, and the messy, fractious challenge of divining something as nuanced as truth.
When the Bucharest video was first broadcast on April 11, nobody heard “Donk,” and this bet seemed destined to be won by those who bet “no.” Then someone noticed that the caster, who through sheer phonetic coincidence is known as Dinko, had botched “don’t.”
Dinko might have known about the Donk bet, so it’s at least possible that he said the fateful syllable on purpose. It’s even possible he placed money on the outcome. He might have made what linguistics fans would call a voiceless velar stop slip.

Jackson Dahl podcasts with me and Nabeel on aesthetics
Filmed at home, this ran about two hours, and yes that is Nabeel Qureshi, with a cameo from Spinoza toward the very end. From Jackson:
From the episode summary:
Tyler and Nabeel are good friends, and given how prolific Tyler is, I decided to use Nabeel as an entry point and interview them together. We discuss sacred commitments, AI acceleration, mentorship, friendship, and more, but I focused the majority of the conversation on art and aesthetics. Tyler and Nabeel are unlikely aesthetes given their day jobs, but in fact take art deeply seriously. They have a shared love for and similar tastes in art, music, and film, in particular. We discuss strange and beautiful art, aesthetic stagnation, and a wide range of favorites: The Beatles, Mozart, Mondrian, Springsteen, Lana Del Rey, Kanye West, Cassavetes, The Sopranos, Apichatpong Weerasethakul, and more.
https://www.youtube.com/watch?si=wC78q_BeD27XDnLN&v=qPHV-BezoIc&feature=youtu.be
Excerpt:
Tyler: (18:31) I think I’m very mundane in many ways. When Marc Andreessen had that famous tweet about not being too introspective, I know he got slammed for that, but I sympathize with that in many ways. I have my work. I focus on it. I want to go see places I haven’t seen before. That really drives me. I feel pretty well motivated. I do think all kinds of deep thoughts, but to me those deep thoughts feel more superficial than my so-called superficial urges to go around doing things. And I’m fine with that.
…Jackson: (23:25) Do you experience art primarily by thinking or by feeling?
Tyler: (23:29) I don’t even know what those words mean. I experience it by looking at it. I don’t think I have very deep emotional responses. I think it’s pleasure and I feel I learn a lot from it. When I go out and look at other works of art or just the world, I see a lot more than people who don’t live with art. I don’t think I feel that much. I’ve never cried in front of a painting. When I read these accounts of someone seeing a Madonna and weeping, it makes no sense to me. It’s like people who do sports gambling. Why do you do that? There are positive-sum gambles for you. Here are a few.
There is much more of interest, self-recommending!
