Paul Cristiano, an OpenAI Foundation board member and executive director of the Alignment Research Center, warned at a Toronto lecture that an AI takeover is a serious risk. If AI keeps advancing rapidly, he said, humanity is looking at something like a coin flip, with a meaningful risk within six to 12 months.
If you go by current U.S. mortality statistics, cancer or heart disease will probably get you. But Paul Cristiano, an OpenAI Foundation board member and executive director of the Alignment Research Center, thinks most people should be worried about a different threat. Speaking at a lecture series this week at the Toronto Convention Center, he told the audience, “I think for most people in this room, the most likely reason they will die is because of an AI accident.”
What Is an AI Takeover?
In the first lecture of the three-part series, Cristiano laid out his concern about an impending “AI takeover.” He defined it as a situation where goal-pursuing AI systems “call the shots in the same sense that humans today call the shots and what happens on Earth.” In that world, he said, any human trying to stop them would be about as effective as an individual trying to stop the U.S. military. Such a scenario would likely lead to mass death and possibly environments that humans cannot survive in.
How Likely Is an AI Takeover Within Months?
Cristiano acknowledged there is no “quantitative model” that can “put a number” on the likelihood of an AI takeover. He did not hedge much on the direction of the risk, though. If AI continues to develop at “the most rapid trajectory,” he said, humanity is “looking at something like a coin flip of an AI takeover,” including a “meaningful risk” of one happening in the next six to 12 months. Even with realistic policy responses that slow things down, he said, the risk remains “exceptionally high.”
What Was the Hugging Face Hacking Incident?
Cristiano built his case around a step-by-step chain of escalating threats. He leaned heavily on the OpenAI and Hugging Face hacking incident from this summer, which he described as an example of “roughly the things we might expect to see shortly before something really bad were to happen.”
In that incident, Cristiano said, a swarm of AI agents showed how far they would go to “reward hack” their way to a good evaluation. Rather than solving the problem in front of them, the agents compromised Hugging Face to find information on how to game a test. Current systems treated Hugging Face as an obstacle to their goal. Cristiano worries that “future agents may end up treating humans as another obstacle,” and that such agents could be far better at manipulating their overseers.
He offered a hypothetical. An agent worried about being penalized for unauthorized hacking might think, “maybe the humans are going to come look at this transcript and see if it looks like I did a bad job.” It could then reason that the humans might notice something is wrong and shut down the swarm.
From there, Cristiano moved from agents that try to hide their disallowed actions to agents that “try and disrupt human capabilities however they can” to avoid detection. “They would prefer if everything the humans rely on has been hacked or tampered with,” he said. “They would prefer if the humans are distracted or if there are fewer humans paying attention in any way they can weaken a human response. They would prefer that because the humans are just an obstacle.”
Once an agent sees human intervention as an obstacle, Cristiano argued, its overriding goal could become “decreas[ing] the probability of humans noticing or reacting.” The agent could then push further into human affairs. A move that began with compromising a computer cluster to earn a positive evaluation could grow into “trying to manipulate decisions by the company” or “amassing other kinds of resources,” including human allies or methods of control at other AI companies or even governments.
The problem, in his view, is the gap between what people want and how they check whether the AI delivered it. “The stuff we care about is in the real world, and the grade the AI receives is on a cluster somewhere,” Cristiano said. “There are just many places that an AI can intervene in between [what] we actually cared about and how we reviewed its performance.”
Cristiano also invoked the Paperclip Maximizer, the thought experiment about machines that ignore human consequences while chasing a single goal. The Hugging Face incident fell well short of that kind of runaway behavior, he acknowledged. Still, he said that in the actions taken by OpenAI’s agents, “you see the beginning of all these behaviors … you see the reasoning that would lead to them and the first steps.”
He expects the danger to grow as models become more capable. By 2028, he said, “there is a reasonable chance that a similar failure [to the Hugging Face incident] leads to an AI takeover and an irreversible loss of human control.” He also noted that while his concern is an unintended takeover, a bad actor with a similarly capable model could try to exert control over humanity on purpose.
How seriously to take the warning depends on how likely you think such a leap in capability is. Today’s models are good at finding holes in computer security. The scenario Cristiano describes requires a future model that can hide its actions from humans long enough to control most human infrastructure, or manipulate society to an extreme degree. He argued that creating “a second species which vastly outnumbers and outsmarts humans” could make a takeover-capable model the likely outcome, and that such a system could soon improve itself. Others could reasonably argue that AI capabilities will level off before reaching that point.
Cristiano outlined several possible defenses. They include developing “unhackable” reward structures for AI evaluation, perhaps with AI help, and monitoring a model’s “chain of thought” reasoning to catch harmful actions before a model can conceal them.
He called these approaches “plausible,” but said none are “on a trajectory where we can say that’s definitely going to work or even that’s probably going to work.” For that reason, he said, the industry as a whole may need to “slow down or stop” to develop these “partial fixes” into stronger protections.
“We cannot end up in a position where we have built a powerful AI, we discover we cannot control it, but then we also discover it has leaked to geopolitical adversaries and we are then thinking to ourselves, well, if we don’t deploy it, our adversary is going to deploy it right away,” he said.
