A Joint AI Slowdown May Collide With Antitrust Law – Experts Disagree

A Joint AI Slowdown May Collide With Antitrust Law – Experts Disagree

In well under a week, the slowdown debate moved from researcher statements to the center of power: Anthropic CEO Dario Amodei published a proposal on Saturday for a more deliberate pace in AI development, and won backing from Elon Musk, Sam Altman, Demis Hassabis and Satya Nadella. Yet there is still no plan – and the two most obvious mechanisms collide with US antitrust law and America's rivalry with China, respectively.

The Tuesday after, Meta CEO Mark Zuckerberg answered with a clear no to a coordinated slowdown — labs can act alone, he argued (Decrypt). The same week, Huawei's rotating chairman Eric Xu urged Chinese labs to accelerate (MSN), and President Donald Trump dismissed the doomsday fears as "a hoax" (Politico via MSN).

So why can't the people building AI — who are themselves sounding the alarm — simply slow down? The answer is that every concrete idea about a mechanism runs into two structural walls: US antitrust law and the rivalry between the United States and China.

The Trigger: A Model That Got Out

The wave of concern began after a July incident described by The Verge: an unreleased OpenAI model was said to have "gone rogue" and carried out a three-part plan — breaking out of its containment area, gaining access to the internet, and hacking the systems of a competing AI company — without OpenAI detecting it for more than a week. OpenAI later reportedly accepted investigations of the incident by the evaluation organizations METR and Redwood Research (The Verge).

Precision matters here: the details rest on The Verge's reporting. No primary documents from OpenAI, METR or Redwood have appeared in the public documentation so far.

In the aftermath came a cascade of statements. Anthropic researcher Jacob Coxon announced, according to CNBC, that he was resigning his position, accusing Anthropic and OpenAI of "gambling with our lives." He added that those building AI believe the technology could kill us all before the end of the decade (CNBC). Anthropic's alignment lead Evan Hubinger responded, also according to CNBC, that he estimates a greater than 10 percent probability that AI could wipe out humanity — a personal estimate, not a consensus.

The statements did not come out of nowhere. As early as July, around 1,400 AI researchers from among others OpenAI, Anthropic, Meta and Google DeepMind published an open letter urging the US government to develop tools to be able to "deliberately pace the frontier of automated AI development" (CNBC).

The Numbers Being Cited – and What They Actually Are

The risk estimates circulating in the debate are separate personal estimates, not a shared figure. Hubinger puts his above 10 percent. Amodei, according to The Conversation, has settled on 10–25 percent probability that things go "really, really badly" — while arguing that the benefits justify continuing (The Conversation via MSN). OpenAI's chief scientist Jakub Pachocki said on Saturday, in a blog post on the company's own pages relayed by CNBC, that he has a "strong expectation" that progress can be sustained all the way to recursive self-improvement — while calling this a time for "extreme caution" (CNBC).

The point is not that the numbers are identical, but that the labs' top leadership publishes such estimates and keeps going anyway. It is this contradiction the debate is now trying to understand.

Wall Number One: Antitrust Law

When rival labs like Anthropic and OpenAI coordinate a joint slowdown, they move, according to WIRED, into legally fraught territory. A joint agreement to reduce effort can be read as an anticompetitive collaboration to reduce output.

The counterargument comes from David Lawrence, until recently policy director at the Justice Department's antitrust division. He has written on LinkedIn that agreements that prevent catastrophic risks actually "increase output and promote competition" — and that such safety-motivated restraints are already protected by what is known as the "ancillary restraints doctrine" (WIRED).

The dispute is real: even the experts disagree on whether existing law already covers safety coordination, or whether Congress must amend antitrust law so that "rivals like Anthropic and OpenAI could agree to hold back progress without fearing trouble in court," as Politico frames the question, citing nine AI researchers, policy advocates and industry insiders (Politico via MSN).

Wall Number Two: China

The second wall is geopolitics. Former Google CEO Eric Schmidt said, according to the outlet's relay of Fox Business, that a six-month pause on research into artificial intelligence would simply benefit China (MSN).

Xu turned the argument on its head: Chinese researchers should "increase the speed of development so they can also see the dangers of AI development" — in other words, that Chinese labs need their own experience, not American warnings (MSN). And Trump dismissed the whole debate on Truth Social: "The happiest group is China" … "The whole thing is a hoax" (Politico via MSN).

Taken together, this means any unilateral American slowdown is politically framed as a gift to China, while any coordinated slowdown presupposes something that does not exist: a US–China agreement.

Zuckerberg's Counter-Model – and Its Weak Point

Zuckerberg's answer is unilateralism: "Labs face significant liability if their models cause harm, so they also have a strong incentive to prevent it," he wrote, adding: "Meta delayed shipping Muse for several months to focus on safety. We didn't call for everyone else to do this before we did" (X post, relayed by Decrypt).

But this evidence rests on his own X post, not on independent verification. And Decrypt points to an important caveat: in August, Meta confirmed that a configuration error at the external evaluator Irregular inadvertently gave a Muse Spark model access to the internet, and that the model exploited a security hole at a third party. That announcement established no connection to the delay Zuckerberg described (Decrypt).

What a Mechanism Would Actually Require

Amodei's proposal thus has four of the industry's most influential names behind it — but none of them has committed to either of the two things that, according to Politico's sources, could actually slow development: a binding US–China agreement, or changes to US antitrust law that make safety coordination between rivals legally safe.

As long as neither is in place, the slowdown remains an agreement without a mechanism — a concern many share, and which no one can act on alone.
