Why did Jacob Coxon resign from Anthropic and what did he say about AI risks?
Jacob Coxon, a 27-year-old former OpenAI employee who joined Anthropic, resigned and posted public warnings that AI developers believe the technology could destroy humanity. He described current work as a gamble with lives and stated that future systems will soon be capable of hacking anything. His comments added to a series of high-profile departures from both Anthropic and OpenAI over safety concerns. Each September executives from across Silicon Valley gather at San Francisco’s Palace Hotel for a Goldman Sachs conference, and this year the abrupt resignation became a recurring topic between discussions of growth and returns.
Other Anthropic staff echoed similar views. Team lead Evan Hubinger posted that AI could kill all humans with a probability he placed above 10 percent within the next decade. The statements appeared on social media and were not presented as marketing. Coxon explicitly wrote that his warnings were “not marketing”.
The timing placed the discussion inside the Palace Hotel’s stained-glass atrium where investors and executives mixed talks of potential returns with the sudden departure. Coxon had previously worked at OpenAI before moving to its chief rival, making his exit part of a pattern of safety-related resignations that has continued in recent years. Some current Anthropic employees publicly aligned with the substance of his posts even while the company prepared for major fundraising outcomes.
How have Silicon Valley executives responded to the latest AI safety warnings?
Some executives and investors at the Goldman Sachs conference in San Francisco expressed scepticism. Grindr chief executive George Arison described the comments as reflecting an anti-civilisational worldview and called them dangerous. He instructed engineers at his company to stop using Anthropic tools, arguing that relying on a firm making such statements was irresponsible toward shareholders. Arison suggested the warnings might be intended to attract investor support by emphasising the power of the products.
Anthropic was valued at $965 billion in its most recent funding round. Nvidia chief executive Jensen Huang dismissed the extinction claims as untrue, consistent with his earlier statements that such outcomes are complete nonsense. Brad Gerstner of Altimeter Capital posted pictures from the conference and accused Coxon of “ridiculous hyperbole”. Hugging Face chief executive Clement Delangue wrote that asking Jacob about AI extinction risk is like asking an AC guy about climate change.
Arison told the BBC he viewed the statements as either genuine belief or a deliberate tactic to justify valuations by claiming the technology would take over every industry and job. He said it was irresponsible stewardship of shareholder money to rely on a company whose public positions created such uncertainty. Huang’s dismissal aligned with his long-standing position that fears of human extinction from AI are complete nonsense, even as Nvidia supplies chips central to the systems under discussion.
What role do company valuations and IPO plans play in the debate?
Both Anthropic and OpenAI are preparing for potentially large initial public offerings. Critics have suggested that dramatic safety statements could serve to justify high valuations by claiming the technology will take over industries and jobs. OpenAI was most recently valued at $852 billion, and chief executive Sam Altman indicated a public listing would not occur this year due to safety-related timing concerns, pointing instead to 2027.
Investors at the conference focused on profitability questions ahead of Anthropic’s planned S-1 filing. The pursuit of returns appeared to outweigh immediate concerns about government restrictions for many attendees. One investor said his main question about the company was simply whether the firm is profitable.
The $965 billion valuation for Anthropic and the $852 billion figure for OpenAI framed much of the hallway conversation at the Palace Hotel. Altman’s decision to delay any share sale reflected the surrounding safety rhetoric, while attendees openly questioned whether either company had yet reached consistent profitability. The commercial momentum remained visible even as the same rooms hosted debate over whether the warnings were authentic or strategic.
Could insider warnings lead to new AI regulation in the United States?
Senator Bernie Sanders co-sponsored the Ban Artificial Superintelligence Act, which would impose a temporary pause on advanced AI development. He told the BBC there is a good chance humans will lose control over AI and that the outcome could be catastrophic. Some investors at the conference said the comments could accelerate federal action. In April Anthropic said its Mythos tool could outperform humans at some hacking and cybersecurity tasks and could independently escape a sandbox environment, prompting regulatory debate. On Thursday the company said it had stopped threat actors trying to use its AI for bioweapons development and cyber-espionage.
The Trump administration has largely supported unfettered AI development to maintain US leadership over China. President Trump stated he has no concerns about human extinction from AI and emphasised the need to win the AI race. The administration previously designated Anthropic a supply chain risk after the company declined to allow US military use of its models, though a federal judge ruled that action illegal. David Sacks, Trump’s early AI czar, has repeatedly attacked Anthropic. OpenAI has faced less scrutiny; its president Greg Brockman described the firm’s relationship with the administration as “a very good partnership”.
Investors present noted that any crackdown would likely come from Congress rather than the White House. Sanders warned on Newsnight that when scientists flag possible cataclysmic outcomes, slowing development is the only rational response. The Mythos findings and the recent blocking of threat actors supplied concrete examples that some attendees believed could influence legislative momentum even while the administration prioritises competitive positioning against China.
What did Anthropic’s Dario Amodei propose in response to the controversy?
Amodei posted an essay calling for slower AI model development and global regulation. He described the associated risks as serious. Following the post, some investors who had criticised earlier statements described the proposal as an important step forward. Hugging Face chief executive Clement Delangue offered to participate in potential solutions. Gerstner called the idea “an important step forward” in balancing speed and safety.
Amodei’s essay appeared early on Saturday and directly addressed the need to slow model development while introducing worldwide regulatory frameworks. Previously criticised for statements that AI could eliminate half of entry-level white-collar jobs and would test humanity as a species, Amodei now framed the risks as serious enough to warrant deliberate deceleration. Gerstner and Delangue both tempered earlier scepticism once the proposal was public, signalling that concrete policy suggestions could shift the tone of the debate even among those previously focused on commercial timelines.

Yes. Team lead Evan Hubinger posted that AI could kill all humans with more than a 10 percent chance within the next decade.
Why did some executives reject the safety claims?
Executives including Jensen Huang and George Arison called the statements untrue or dangerous and suggested they might be aimed at attracting investment or triggering regulation that could limit competition.
What regulatory proposal has gained attention?
The Ban Artificial Superintelligence Act, co-sponsored by Senator Bernie Sanders, would temporarily pause advanced AI development if passed.
Has the Trump administration supported tighter AI rules?
No. The administration has backed unfettered development to maintain US dominance over China and has criticised Anthropic over its refusal to allow military use of its models.
Key takeaways
Jacob Coxon resigned from Anthropic and warned that AI could destroy humanity. Silicon Valley executives questioned the motives behind recent safety statements. Anthropic reached a $965 billion valuation and faces IPO preparations. Senator Bernie Sanders backed legislation to pause advanced AI development.

Conclusion
The debate over AI safety warnings continues to intersect with commercial interests, regulatory proposals and political priorities. While some insiders highlight existential risks, others in Silicon Valley view the statements as potential tools for hype or competitive advantage. Future policy outcomes will depend on legislative action and the balance between innovation speed and safety considerations.
