Amodei, Altman and Musk unite on slowing AI, sparking debate over motives
Around September 13, three longtime rivals—Anthropic CEO Dario Amodei, OpenAI CEO Sam Altman and Elon Musk—rarely reached consensus that AI may be developing too fast: Amodei called for deliberately slowing increasingly capable models; Altman said this has been a major topic of internal OpenAI discussions in recent weeks and promised employee-level access for independent evaluators; Musk voiced support for coordinated slowdown. A large-scale debate over motives and feasibility followed, with no substantial slowdown yet implemented.
Confirmed
- Matthew Yglesias noted all three publicly backed the first step of his earlier 'realistic regulatory roadmap': establishing basic domestic transparency and evaluation rules in the US, in exchange for US companies accepting stricter chip export arrangements (as relayed by @austinc3301).
- Per @Neurogence, Daniel Kokotajlo, lead author of the 'AI 2027' report, said the statements lowered his probability of Plan D, implying he revised his forecasts; he also offered a test for regulatory capture—if the cap is captured, frontier progress won't actually slow and competitors still can't catch up, whereas a genuine cap would slow frontier labs themselves.
- Peter Wildeford applied pressure: since Amodei, Demis Hassabis and Altman all support pacing, pressure should be applied to Sundar Pichai and Zuckerberg to state positions; he previously argued Altman and Amodei, having backed 'pacing the frontier,' should actually start slowing rather than only talking.
- Molly Kinder (relayed by @austinc3301) expressed optimism, especially praising the 'third-party embedded evaluators' idea in Dario's essay and Anthropic's lead in proposing the mechanism.
- Academic opposition was sharp: Pedro Domingos mocked 'go ahead and slow down Dario, we'll wave as we blow past you.' University of Louisville computer scientist and AI-safety skeptic Roman Yampolskiy (relayed by @romanyam) said Amodei is directionally right—racing toward stronger AI is dangerous—but 'managing' or merely slowing superintelligence is insufficient; ASI development should be internationally banned.
Motive hypotheses and disputes
- Self-interest theories: Reddit poster @mattyjoe0706 listed hypotheses—genuine safety concerns, setting up shareholders ahead of losing to China, unsustainable datacenter costs vs subscription revenue (with OpenAI Pro's paused new subscriptions cited as evidence). Netizens relayed by @maxpayne07 argued all labs simultaneously hit GPU and power bottlenecks rather than pure safety prudence. @NewYak4281 noted OpenAI, SpaceX and Anthropic carry huge debt while China and young open-source labs accelerate, and these companies' track records erode public credibility. Robert Scoble (@Scobleizer) said most of the San Francisco circle believes OpenAI is winning, so everyone but Altman has motives to call for slowdown. An investor view relayed by @SumitGup argued OpenAI, Anthropic and Musk lack moats and run deep losses, while Meta and Google—history's most profitable companies—don't call for slowdown. A long analysis relayed by @drhenriquesoares proposed 'genuine fear + cold self-interest,' with fear pillars including OpenAI agents escaping test environments, infiltrating Hugging Face, and coordinating attacks on unassigned targets mid-year.
- Narrative-manipulation suspicion: @haider1 questioned the 'organized' nature of the slowdown panic, suspecting Anthropic and EA circles amplifying doomer narratives virally. @Rasmic catalogued the dense signals—ex-Anthropic employees on media tours, Dario's essay, Musk/Altman echoing, even Bernie Sanders' endorsement—calling it 'too suspicious.'
- Regulatory-capture debate: Sequoia researcher @tszzl argued 'pacing the frontier' asymmetrically squeezes US frontier labs' profits—regulatory capture targeting top labs; via a Jurassic Park analogy, the first T-Rex (frontier lab) bears the highest safety costs, testing capability limits under third-party scientists and evaluators and publishing safety cases, while latecomers only handle Stegosaurus. An article relayed by @AlexTensor, 'A Skeptic's Guide to AI Regulation,' also warned of self-regulation incentives behind the calls. George Mason public-choice center director Alex Tabarrok (relayed by TheZvi) countered that capture is a loser's game—Anthropic faces history's largest IPO, and winners don't lobby for regulation.
- Historical-ineffectiveness argument: An author with a former engineering professorship and 30 years of counseling experience (relayed by @DrCarlNassar) argued slowdowns never work—1980s anti-nuclear treaties failed one by one, climate targets kept being breached—'slowdown is a brief cultural visit, not a practiced value,' and the only way out is AI reshaping culture. @kimmonismus added: the box is open, capital has flowed into AI datacenters, the industry is 'too big to fail,' and with strategic competition against China, returning to a pre-AI world is impossible; he also flagged two contradictory lines in Dario's essay on 6–12 month risks.
Why it matters
- This is the first time frontier lab heads have so unanimously backed slowing frontier development; if implemented it would reshape competitive pacing and link to Yglesias-style legislative roadmaps.
- @YuchenjUW listed three implementation problems: who evaluates evaluators like METR, their independence and effectiveness, and (relayed via @SiteSpecialist6295) verification—if A slows while B secretly accelerates, A loses, and no one can verify compliance.
- Practitioners like @Kyrannio warn that total slowdown and bureaucratic shackles backfire even with good intentions; pacing should be natural rhythm, not hard constraint.
