Background: I am co-teaching (with Kent Daniel) a grad course at Columbia titled "Quantitative Investing". I can share my slides, starting with the ones on market structure (ch.1 in my 2nd book). Below are a few representative slides. I will share the lecture on linear return models this weekend. At some point also one lecture on very high-dimensional linear models, which are interesting. For now link to first deck is in reply. Enjoy.

I'll take that as agreement, thanks. How are we supposed to understand, in particular, the thinkng of the Founders without knowing at least some of what the Founders knew? And what the Founders studied above all was history - Greece. Rome, Christendom, Europe.
This is a serious issue. The principles behind the Constitution were meant to solve problems in ancient republics. They also presuppose a certain type of man. Teaching the founding thus requires a consideration of human nature and the form of government appropriate to it. And that question divides the tradition into camps, whose positions need to be elaborated and whose disagreements need to be adjudicated. Or, to quote Publius, “But what is government itself, but the greatest of all reflections on human nature?”

In 2023, @gclarkecon argued in PNAS the long-run persistence of social status fits an additive genetic model with assortative mating. The main critique was that pedigree data alone couldn't rule out a social transmission model. The last few years seem to vindicate him. 🧵(1/4)

This tweet can be summed up in a sentence: Now that East Asian and Indian kids are doing better than white kids in school and the job market, we need to rethink meritocracy. It's the same logic that led colleges to put quotas in place to limit the number of Jewish students.

Jerry Z. Muller: academia today, intellectual history in the past and AI in the future razibkhan.com/pub/razib/p/je… Today Razib talks to Jerry Z. Muller, a historian and professor emeritus of history at the Catholic University of America in Washington, D.C., specializing in modern European intellectual history, capitalism, conservatism, and German and Jewish history. His work explores how ideas shape economic, political, and cultural life, bridging history, philosophy, and public policy. His books include Conservatism: An Anthology of Social and Political Thought From David Hume to the Present, The Mind and the Market: Capitalism in Modern European Thought, Capitalism and the Jews, The Tyranny of Metrics, and Professor of Apocalypse: The Many Lives of Jacob Taubes. Writing for both scholarly and general audiences, Muller examines subjects ranging from the moral arguments surrounding capitalism to the consequences of relying excessively on numerical measures to evaluate institutions and individuals. He has an eponymous Substack. The conversation revolves to a great extent on a recent post by Muller, Rethinking Faculty Control Scholarly Norms, the Vanderbilt Report, and the Limits of Academic Self-Government. Razib and Muller discuss the challenges facing universities, the resilience of American capitalism, and the effects of AI on intellectual life. Muller argues that scholarship depends on “organized skepticism,” including peer review, replication, and engagement with different viewpoints, but that activism and ideological conformity weaken these practices in parts of academia and undermine public trust. They also tackle whether stronger university leadership can help address these problems while managing declining literacy and numeracy, shifting demographics, uncertain international enrollment, rising costs, and pressure to demonstrate results. Muller suggests that vocational training may increasingly separate from liberal arts education and research, raising questions about how universities can adapt while maintaining academic standards and intellectual diversity. He remains broadly optimistic about American capitalism, pointing to technological innovation, competition among states, immigration, and social supports. Both view AI as a powerful tool for skilled thinkers but a potential source of intellectual passivity for others, raising the question of how people can preserve their agency and sense of purpose as AI becomes part of everyday intellectual work.

This post led me to meet the most remarkable founder solving this problem. X is the greatest tool for business in the world.
Bot detection & human verification will be one of the most urgent demands for businesses over the coming years. Agent swarms will suffocate every website and form; small companies and government websites are most vulnerable. There is a huge gap in the market for this right now. When we looked at what offerings were in the market to use at X, there was not a single company that brought together all the latest technologies so we had to do it all in-house.

Must we solely rely on the AI Labs and government to protect us from AI risk? We have many private ways to self-protect against this risk. I explore this adaptation point in my new paper. drive.google.com/file/d/1wnE…

If a large nation has private medical data accidentally publicly accessible to a zero-spoofing/phishing agent, the person most to blame is the IT staff who work for the government, not OpenAI! Responsibility...
Australia has been hacked. 'And today, I spoke with the CEO of OpenAI, Sam Altman, to express Australia's extreme concern about this incident. And I also expressed my disappointment that it took the company way too long to inform the government what had occurred, and the nature of the way that that notification occurred as well was unacceptable.'

Agree with caveat that "big increase in productivity" is very very very unlikely to be bad for workers overall.
This fall in prices is one of the reasons I'm skeptical of pro-worker AI arguments for shifting the direction of innovation. Cheap and ubiquitous Astra/Fable+ level intelligence is baked in within <2 years. It will be complementary to some tasks and a substitute to others, so the labor market implications are non-trivial. But I don't see how a non-existent pro-worker AI alternative competes.

"Business will certainly need to end many commitments they made during the high-trust, pre-AI world"
Replying to @DanielMuvdiYT
Not all the things people do with bots are a simple extension of human behavior. In fact, the most widely publicized examples are exploitation: • DDoS’ing businesses for refunds • Spamming replies on X to promote to your cryptocurrency • Filing frivolous lawsuits • Flooding restaurants with potential reservations • Scalping all concert tickets with agents Business will certainly need to end many commitments they made during the high-trust, pre-AI world—but it will not happen overnight and our systems will crumble during the transition without any defenses.
