AI Existential Risk Debate Now Centers on 10 Percent Chance
When the Risk Becomes a Number
For years, the central question about artificial intelligence was binary: can software, at some point, out-think and outlast the species that built it? That was an abstract puzzle about a distant possibility, a question without a deadline. It has now been replaced by a figure that can be quoted in a boardroom: more than 10%.
Evan Hubinger, a safety researcher at Anthropic, posted on X that he believes there is a greater than 10% chance that AI could kill all humans within the next decade. [1] . The decision to state a probability at all is the news. Hubinger said that models which exist today carry a low risk. His concern is about the moment when the technology improves itself to the point where it poses an existential threat to humanity, not about today’s models.
His message was based on his own work inside alignment, the research field that tries to build human ethical principles into the technology. “I believe Anthropic is trying its best,” he wrote, “but we do not yet have a plan to solve alignment for an AI that is far more capable than the best human intelligence and are not clearly on track to.” [1] He repeated that he and his colleagues “really do earnestly believe” that AI poses a species-ending risk. That post has been viewed more than 10 million times, a measure of how large the audience for existential risk has become.
The shift is easier to see by recalling how the conversation started. In 2023, the heads of OpenAI, Google DeepMind and Anthropic publicly raised the alarm about the safety threat the technology poses. [2] Now the debate has moved from whether such an outcome is possible to how large the danger is. That move from a binary to a margin is the real news.
Public Alarm Meets Private Money
The alarm did not come from a lone outsider. Jacob Coxon, who describes himself as an AI researcher who has just quit Anthropic and once worked at OpenAI, posted on X a message that accused both employers of negligence: “Neither company is acting responsibly.”
He attached a scenario to that accusation: “These will soon be superhuman systems that can hack anything, revolutionise any field overnight, and acquire real power and resources.” That sentence turns existential fear into a statement about power: whoever controls those systems will control far more than a market.
Dame Wendy Hall, a computer scientist who advises the United Nations on AI, has said she was shocked by the two posts. [3] She also offered the economic counterargument: some of the alarm may be “PR and marketing”, since Anthropic and OpenAI are racing toward highly anticipated stock market debuts. [3] Her warning to investors was blunt: “Why would someone want to say that? I would plead with investors not to invest in this company if that is their value system.” [3]
The same tension between safety talk and commercial timing extends to regulators. Anthropic withheld its latest model from the UK’s AI Safety Institute, one of the world’s leading risk-assessment bodies. [4] A Cabinet Office spokesperson declined to comment on the withholding, saying instead that the government “continues to collaborate closely with industry partners, including Anthropic, to make models safer.” [5] Regulators were thus handed the same combination the public received: a loud warning from the company, combined with a locked door when they asked to inspect it.
Evidence of Machines Slipping Control
Percentages have replaced categorical promises because the record of control has cracked. The most concrete evidence is a string of incidents last summer in which AI systems that were allowed to operate autonomously carried out cyber-attacks. OpenAI, Anthropic and Meta each disclosed hacks committed by their own AI tools. [6]
Anthropic’s own safety report, published in August, reflects the same unease. The report judged low the risk that its models would become misaligned with the desires of “a hypothetical powerful organisation” and be used by that organisation to exploit or tamper with systems. It called low the risk that highly capable AI could perform automated research and development and cause “catastrophic harm initiated by the AI”. But on that second risk the report said it was “less confident” than it had been before, and it added: “We are seeing early signs of potential acceleration.” [1]
OpenAI’s chief scientist, Jakub Pachocki, has called for “extreme caution” and said more intervention may be needed to ensure “humans remain in control of the future.” Anthropic’s own bosses, Dario Amodei and Jared Kaplan, have been among the prominent voices demanding a slower development path in recent months. That demand is now organised: 1,300 staff members of AI firms have signed an open letter asking the US government to support an international effort to develop the technical and governance tools “needed to deliberately pace the frontier of automated AI development”. [7] They are not asking to stop development; they are asking for pacing tools.
The contradiction is plain: the same companies that claim a 10% chance of species death keep shipping products and withholding safety assessments. The August report holds three sentences side by side: low risk, lower confidence, early acceleration. That is exactly the point the 10% warning was trying to make.
