Robert Booth and Julia Kollewe's 'OpenAI Boss and Elon Musk Back Calls to Put Brakes on Reckless AI Development'. A Warning Is Not a Brake.
The fastest agreement in AI history happened this weekend, and it cost nobody anything.
Sam Altman and Elon Musk both endorsed Dario Amodei's call to slow down1, Robert Booth and Julia Kollewe report. Altman said he agrees "that we need to pace the frontier", backed independent evaluators with deep access to company systems, and said OpenAI would postpone its public offering on safety grounds. Demis Hassabis: "The details need working through, but the direction is correct." Musk: "Dario is right." He also reposted his own warning from 20232, that AGI is "significantly higher risk than nuclear weapons".
Four of them, inside a weekend, on a proposal published days earlier. Set against the usual pace of anything in this industry, that is not consensus forming. That is a bill passing unopposed because nobody has to pay it.
What did any of them surrender? Nothing. The scheme runs on evaluators each company invites, contracts and can decline to renew, so agreeing to it removes no option any of them currently holds.
Then there is the objection. David Sacks, co-chairing the president's science advisory council, attacked the whole thing, saying companies should act on their own rather than ask government permission, and should stop claiming altruism while sitting on "massive product-liability exposure".
He is arguing against the proposal. He is also the only person quoted in the piece who names a force that does not depend on anybody's goodwill. Everyone agreeing is doing ethics. The man disagreeing is doing accounting, and accounting is what has historically stopped things.
Put two numbers from the same article side by side. Jacob Coxon, who left Anthropic over it, warns of human extinction by 2030. From this month to the end of 2030 is about 51 months. The alignment and interpretability work Amodei wants the extra time for, he dates at one to two years, so 12 to 24 months. Twenty-four over fifty-one is a shade under half. On the most alarming estimate in the piece, the remedy consumes up to half the time remaining. Those are two different kinds of claim and neither is a measurement. That is rather the point: nobody in this story is working to a number anyone could check.
By 31 December 2028, a frontier AI company's published annual report or risk filing will name product-liability exposure as a reason it delayed, limited or withdrew a model release. One filing settles it, and if none says it, Sacks was wrong and so was I.
The case the other way is strong. These four are the only people who have watched these systems fail from the inside, and a norm agreed early is how every safety-critical industry started. Professor David Krueger says the proposal "does not reduce the risk to an acceptable level", which assumes a scale of acceptability nobody has built. And liability is a miserable brake for exactly the harm everyone says they fear: it arrives after the damage, and the damage is the part you cannot undo.
The Guardian dates Musk's first warning to 2014. Potentially more dangerous than nukes. Twelve years on, the agreement everyone could sign in a weekend is the one where each company invites its own inspector.
