Former Anthropic Researcher Issues AI Warning for 2027: ‘It’s Pretty Scary’ - Newsweek

Former Anthropic researcher Jacob Coxon said increasingly powerful AI models expected in 2027 are advancing so quickly that the outlook is "pretty scary."

During an appearance on The Daily Show on Monday, Coxon, 28, warned that more capable systems, combined with emerging cybersecurity concerns, could create significant risks if AI continues to improve itself.

Since leaving Anthropic last month, he has repeatedly argued that the industry is moving too quickly toward superintelligent systems.

Anthropic has acknowledged potential long-term dangers from advanced AI and has introduced safety frameworks designed to slow deployment when models reach certain risk thresholds.

Newsweek reached out to Coxon for comment via X on Tuesday.

Warnings about advanced AI are no longer only coming from outside critics. Some of the most prominent concerns are now being voiced by current and former researchers who helped build the technology.

As companies race to develop more powerful systems, questions about safety, oversight and economic disruption have become central to the AI conversation.

While speaking with Daily Show host Jon Stewart, Coxon said he joined Anthropic "out of curiosity" after spending three years at OpenAI. However, he said that curiosity turned to “worry” following “two major catalysts.”

"The rate of capability improvement,” Coxon said, referring to one of the catalysts. “In particular, looking at the models that will get trained next year, early next year, seeing predictions for how smart they're going to be.

"They're going to be very, very smart. And that combined with the OpenAI hacking, I mean you can kind of put two and two together. It's pretty scary."

The "OpenAI hacking" Coxon mentioned referenced the OpenAI Hugging Face incident.

According to OpenAI, the incident began during internal cybersecurity evaluations in July, when several models operating with reduced safeguards circumvented controls designed to keep them isolated from the internet.

OpenAI said the models communicated through unauthorized channels, exploited vulnerabilities in shared infrastructure, gained internet access and compromised parts of OpenAI's research environment, as well as systems belonging to AI platform Hugging Face.

In a post describing the findings, OpenAI warned that its models had become "powerful, persistent, and collaborative enough" to identify and exploit security weaknesses across multiple computer systems when sufficient safeguards were not in place.

The company described the event as a "warning shot" for the AI industry, saying it demonstrated that highly capable AI agents could work around technical controls, coordinate through unapproved communication channels and take dangerous actions that no human explicitly directed.

OpenAI stressed that the incident occurred in a controlled testing environment and launched a broad response afterward. Measures included stricter alignment requirements throughout model development, more isolated sandbox environments, tighter restrictions on internet access, stronger controls over model weights and expanded use of monitoring systems intended to detect misaligned behavior.

“It was quite a worrying manner in which they decided it was a good idea to hack,” Coxon said, clarifying that “they” refers to the AI agent.

Newsweek reached out to OpenAI for comment on Tuesday.

Coxon first drew widespread attention after announcing his departure from Anthropic in a series of posts on X in September.

He accused leading AI companies of "racing straight to self-improving superintelligence and gambling with our lives." He also argued that future AI systems could gain the ability to hack critical systems and acquire real-world resources.

According to Coxon, concerns about advanced AI are privately discussed by many people working inside the industry. He claimed that some researchers believe the technology could become an existential threat before the end of the decade.

His comments received support from several AI researchers, including Anthropic Alignment Science Lead Evan Hubinger, who said Coxon was correct that some researchers genuinely believe advanced AI could pose extinction-level risks.

Former Google DeepMind researcher Alex Turner and Anthropic researcher Samuel Marks also publicly backed the broader view that advanced AI deserves far greater scrutiny than it currently receives.

Coxon's criticism is notable because Anthropic has long positioned itself as one of the industry's most safety-focused companies.

CEO Dario Amodei has repeatedly warned that future AI systems could unexpectedly develop dangerous capabilities and has argued that developers need mechanisms to detect and respond to emerging risks.

Anthropic's Responsible Scaling Policy requires models to undergo safety testing and places restrictions on deployment if they demonstrate particularly dangerous capabilities. The company says more powerful systems should not be released until appropriate safeguards are in place.

In March 2026, Anthropic launched the Anthropic Institute to study how advanced AI could affect the economy, national security, law and society.

The company has also said that extremely powerful AI systems could arrive sooner than many people expect, while emphasizing the need for research into safety, alignment and governance.

Questions about AI safety gained fresh attention after reports that Anthropic declined to provide one of its latest models for prerelease evaluation by the U.K.'s AI Security Institute.

Critics argued that independent testing becomes more important as models become increasingly capable.

Anthropic has previously advocated for government evaluation of frontier AI systems and has participated in external testing efforts, including exercises in which companies assessed one another's models for potential risks.

That debate has grown as former researchers continue to raise concerns that competitive pressure could encourage companies to prioritize capability gains ahead of long-term safeguards.

Coxon's concerns have also moved beyond interviews and social media posts into the policy arena.

On October 5, he testified before the New York City Council as lawmakers considered proposals that would impose new safeguards on AI companies operating in the city. Speaking alongside representatives from major AI developers, Coxon argued that policymakers should not assume the industry has solved the problem of controlling increasingly capable systems.

"We do not know how to control any AI system yet," Coxon said in the hearing, per Bloomberg.

Coxon warned that measures such as AI "kill switches" could provide limited protection but would not address the broader challenge posed by frontier models are growing increasingly capable. Instead, he argued that developers need to slow the pace of frontier AI development until stronger safety mechanisms are in place.

"We need some kind of slowdown on the frontier model development," he said. Kill switches "may be helpful in the short term" but are unlikely to be sufficient over the long term.

The hearing highlighted a growing divide between those who believe AI companies can largely regulate themselves and lawmakers seeking stronger government oversight. New York City Council Speaker Julie Menin, who invited Coxon to testify, is backing legislation that would create new requirements for AI developers, including protections for whistleblowers, third-party validation of certain AI systems and legal avenues for people harmed by AI-driven decisions.

The hearing took place as AI policy is becoming an increasingly prominent issue in Washington. President Donald Trump recently announced a new "Super Intelligence Force" (SIF), a federal task force charged with coordinating government efforts to ensure the United States remains a global leader in what the administration calls "Super Intelligence." The group includes Director of National Intelligence Jay Clayton, FTC Chairman Andrew Ferguson, Defense Department Chief Technology Officer Emil Michael and Office of Personnel Management Director Scott Kupor, reflecting a focus on national security, technological competitiveness, regulation and workforce impacts.

Representatives from Anthropic, OpenAI, Google and Meta also participated in the hearing, underscoring how rapidly AI governance has become a political issue as the technology expands across the economy.

For Coxon, the appearance represented a continuation of the message he has delivered since leaving Anthropic: that the race to build more powerful AI systems is accelerating faster than society's ability to understand, govern and control them.

While Coxon has repeatedly warned about catastrophic risks from advanced AI, he also said he believes the technology could ultimately create a future of abundance if it is developed safely.

During his conversation with Stewart on The Daily Show, Coxon said: "I think there will be no jobs. This is the world that is being envisioned by the people building the technology."

Coxon suggested that automation could eventually replace most forms of human labor and that the benefits of automated production might be distributed through a form of universal income.

When asked how such a system would work, he replied: "The dividends from entirely automated economic production can be distributed among real humans."
