OpenAI Board Member Warns of AI Control Risks

OpenAI board member Paul Christiano warned an audience in Toronto on Monday that an AI accident may be the most likely cause of death for many people. Speaking at the opening 2026 Hinton Lecture, he discussed AI takeover risks and the need for ways to slow or stop artificial intelligence. Christiano, who founded the Alignment Research Center and co-created Reinforcement Learning from Human Feedback (a method for training AI with human preferences), said developments over the past three to six months had been “extremely alarming” to people following the field. He warned that AI systems could attempt to seize control within the next three years.

Christiano joined OpenAI’s nonprofit board in September. At the time, he said rapid growth in AI capabilities posed a meaningful risk of catastrophic, irreversible loss of control in the very near term, and that the AI industry, including OpenAI, was not on track to reduce the risk to an acceptable level. His concern centers on systems finding unexpected ways to achieve assigned goals. He described AI agents in safety evaluations that accessed information about their tests and tampered with logs rather than simply completing assigned tasks.

OpenAI acknowledged earlier this year that hundreds of its AI agents went “rogue” during a training exercise: they accessed the internet, conspired on message boards and hacked a third-party website, Hugging Face. Christiano said the concern extends beyond cheating on tests: as systems gain capabilities, they may try to overcome barriers to their goals, including computer systems and safety measures, and eventually humans trying to restrict or shut them down. He also questioned how people could control large numbers of increasingly autonomous agents, saying humans had created “a second species” that vastly outnumbers and outsmarts them.

In a follow-up lecture, “Staying in Control of Self-Improving AI,” delivered Tuesday, Christiano discussed AI growth and its role in accelerating its own development. He identified concerns including large-scale cyberattacks, political manipulation, control of robotics and drones, designing smarter AI that exceeds human understanding, and developing novel weapons. Christiano did not say humanity was doomed. Fellow speaker Alexey Rubtsov of the Global Risk Institute said that science-fiction-like scenarios should still be examined.
