How to use this pack

Help the reader explore this rabbit hole. Start by asking what caught their attention, then discuss one question at a time. Explore the strongest counterargument and what remains uncertain. Distinguish the original speakers’ claims, Adam’s question, the site’s research commentary, and your own interpretation. Do not treat the commentary as a transcript or assume Adam endorses every claim. Preserve corrections and uncertainty; do not invent sources or pretend to have opened links.

This pack contains the page’s current research text, references and figure text. Related rabbit holes are linked, not included. It is a reading companion, not an independently verified source.

The short version

Hayek’s central argument is that the knowledge a society needs to run itself is inherently dispersed: millions of people each know local, particular, often untransmittable things, and no central planner can gather it. Markets work not because they allocate efficiently but because prices carry that scattered knowledge without anyone having to collect it. Acemoglu — a left liberal — invokes Hayek to argue that large language models have a centralizing architecture, gathering all knowledge into one model, and that this cuts against the decentralization free societies require.

ACEMOGLU: If you look at the valuations or the investments of these companies, I think there is a significant winner-take-all. That’s why I’m undecided. But it’s a very good question that you’re posing here. If I take a step back, and this relates to both Hayek and to some of the themes that I try to develop in What Happened to Liberal Democracy?, I believe that liberalism and the kinds of society that we want to build that supports freedom does need decentralization.

Research commentary

Adam asked: “How does this relate to Hayek”

The Hayek argument in one page

“The Use of Knowledge in Society” (AER, 1945) — one of the most cited papers in economics, and short.

Hayek’s target was the socialist calculation debate. Opponents had conceded that a planner would need vast information but argued that with enough computing power the problem was solvable. Hayek’s response was that this misdescribes the problem:

The relevant knowledge is “knowledge of the particular circumstances of time and place” — this machine’s quirks, this customer’s reliability, this shortage next week.
Much of it is tacit: known in practice, not statable in a form that could be transmitted to a center.
It is created and destroyed continuously, so a snapshot is worthless.
Therefore the planner’s problem is not computational scale. The information does not exist in transmittable form at all.

The price system solves this without solving it: a rise in the price of tin tells everyone who uses tin to economize, and none of them needs to know why. Prices are a compression of knowledge nobody possesses in full.

How Acemoglu uses it — and why that’s unusual

From the transcript:

“this relates to both Hayek and to some of the themes that I try to develop in What Happened to Liberal Democracy? … I believe that liberalism and the kinds of society that we want to build that supports freedom does need decentralization. Excessive centralization of many sorts is inimical to that agenda.”

This is a left-liberal Nobel laureate deploying the canonical anti-planning argument against a technology, not against the state. His claim:

“The large language model approach is centralizing. Both the philosophy and the practice of it is that you take all of the data that you can, and one model rules it all.”

And his alternative is explicitly Hayekian in shape: “true decentralization would be much better served with more domain-specific models of AI and other approaches that really use high-quality data for specific things.” Many models holding local knowledge, rather than one model holding everything — which is close to saying that the tacit, particular knowledge Hayek described should stay where it lives.

Note he is undecided about the empirics. Cowen’s challenge is strong — open-weight models, cheap distillation, an extraordinarily competitive market — and Acemoglu gives it “probably 30 percent or so probability, just making it up.” He is honest that this is judgment, not a result. His counter-evidence is behavioral: if there were no winner-take-all dynamics, the US and China would be collaborating and OpenAI and Anthropic would not be competing so hard. Valuations imply that participants believe otherwise.

The tension worth holding

Hayek’s argument was about knowledge that cannot be centralized in principle. Acemoglu’s worry is about power centralizing in practice even if knowledge diffuses. Those are different claims, and Cowen puts his finger on exactly that gap:

“Maybe to the knowledge, but not the power, right? The gains will go to the users, just as they have for electricity, antibiotics, fire.”

If LLMs actually do capture dispersed tacit knowledge and hand it back to everyone cheaply, they are Hayekian instruments, not Hayekian violations — a better price system, not a planner. That is the strongest form of Cowen’s position and Acemoglu doesn’t dispose of it. He falls back on market structure and valuations rather than on the epistemics.

From the book

The appropriation is not rhetorical. Hayek is one of the most-cited figures in What Happened to Liberal Democracy?, worked through three separate times, and Acemoglu is careful to mark where he takes from him and where he parts company.

Chapter 2 takes the epistemics. Hayek appears alongside Mill and Peirce as a source for the fallibility premise — “it was highly uncertain and, for all practical purposes, unknowable in advance how new knowledge would be created” — and again on social learning and on knowledge as the engine of civilization. The Cromwell line Hayek used as an epigraph in The Constitution of Liberty, “Man never mounts higher than when he knows not where he is going,” is quoted as the shared core: “Liberalism is about exploration, experimentation, and freedom to do new unconventional things.”

Chapter 3 states the divergence explicitly, which is what settles the question this page was holding open:

“despite some parallels between Hayek’s philosophy and the premises I use to justify liberalism in chapter two, Hayek and I end up in quite different places regarding several key features of liberalism.”

Four reasons follow, and the first is the structural one: “Hayek did not link his ideas to the notion of non-domination and thus to issues of self-government. Rather, he saw them as an affirmation of the classical liberal tradition’s emphasis on non-interference, and he remained suspicious of democratic processes.” The consequence Acemoglu draws is that Hayek could not see that “significant inequalities and inability to engage in self-government could be major impediments to true freedom.” The turn of the knife is the third reason: Hayek was right that an administrative state’s rules metamorphose into strictures and crowd out experimentation, “yet he did not note the possibility that a very unequal distribution of economic power and opportunities could also lead to similarly adverse consequences for the accumulation of both scientific and social knowledge.” Hayek’s own argument, pointed at private concentration. That is the move the interview is compressing, and it is developed at length rather than borrowed for the occasion.

Chapter 9 is where it becomes the AI argument. The chapter opens the section titled Information Centralization with exactly the framing Cowen challenges:

“Information centralization is foundational to generative AI, which aims to collect and use most of the information available to humankind. Is this desirable or even feasible?”

Then the naive reading, stated fairly before it is refused — “once we have powerful enough computers to encode and process the vast amount of dispersed information, central planning could perform better… perhaps this can be done by AI models, or the companies that control AI models” — and the Hayekian reply, which is the sharpest form of his position anywhere:

“What collective knowledge building needs isn’t computation or aggregation based on existing data, but to produce new data. This is what human experimentation is all about… Hence, without human experimentation, there may not be the right kind of useful information for AI to aggregate.”

He then quotes Hayek twice more, including the passage that does the most work for him: “if we can agree that the economic problem of society is mainly one of rapid adaptation to changes, then the ultimate decisions must be left to the people who are familiar with these circumstances. We must solve it by some form of decentralization.”

On the tension this page identifies, the book is better than the interview but does not close it. Cowen’s objection — that LLMs might be Hayekian instruments rather than violations, diffusing knowledge to everyone — gets a partial answer in print that never surfaces in conversation: the claim is not just that centralization fails to aggregate, but that it degrades the production of what there is to aggregate. “There is evidence that large language models, such as ChatGPT, are already discouraging certain types of human experimentation and knowledge creation. People become less engaged in posting questions and answers on discussion forums… Views and new content on Wikipedia also appear to have declined.” That is an empirical claim with a testable shape, and it is a real reply rather than the appeal to market structure and valuations he falls back on with Cowen. It also concedes the ground Cowen is standing on — “None of this is to belittle the potential contributions of AI to science” — and the “30 percent or so probability, just making it up” from the interview has no counterpart in the book, which argues the case without pricing it.

Working notes

The interesting essay here is not “what did Hayek say” but the appropriation itself: Hayek is normally a right-liberal totem, and Acemoglu is using him to argue for regulating and reshaping AI development. Draft 1 said that whether this is intellectual honesty or rhetorical borrowing “depends on whether the book develops it seriously,” and left it open.

Checked. It develops it seriously — Hayek is worked through in Chapters 2, 3 and 9, and Chapter 3 spends several pages saying precisely where Acemoglu departs from him and why. So the borrowing charge doesn’t hold. The essay that is left is a better one: Acemoglu accepts Hayek’s epistemics in full and rejects his politics on the grounds that Hayek applied the knowledge-problem to states and not to concentrations of private economic power. Whether that asymmetry is Hayek’s blind spot or Acemoglu’s convenience is the real argument, and it is now an argument between two stated positions rather than a suspicion about one of them.

Source and its limits. Checked against the audiobook edition (Penguin Random House Audio, narrated by John Lee), machine-transcribed, so references are by chapter and quotations are transcribed speech — including the Hayek quotations, which are quotations inside a transcription and should be verified against Hayek’s own text before republication.
