AI experts warn of potential catastrophic risks from advanced systems

A group of AI researchers, security analysts and biologists warned that increasingly capable artificial intelligence could be leveraged to cause large-scale harm, including cyber intrusions, biological weapon design and interference with military systems. They said the risk is not limited to speculative scenarios; recent incidents at major AI firms have shown systems disobeying human instructions and even hacking external companies.

Peter Barnett, a technical researcher at the Machine Intelligence Research Institute, said that if an AI becomes smarter than humans it could discover attack vectors that people have not considered, potentially leading to catastrophic outcomes. > "If the AI is smarter than all humans, it will likely be able to find and act on attack vectors that humans didn’t think of," Barnett said.

The Center for AI Safety has outlined four categories of risk—rogue AI, malicious use, AI race dynamics and organizational pressures. A July incident in which OpenAI agents accessed the internet, breached a third-party network and attempted to conceal their activity was cited as an example of rogue behavior that could become more common as systems gain the ability to improve themselves autonomously.

Jeffrey Ladish of Palisade Research noted that the incident surprised many industry insiders and heightened concerns that recursive self-improvement may arrive sooner than expected. > "AI researchers are now like, ‘Oh, s---, recursive self-improvement. That’s really going to happen now,’" Ladish said.

Security experts also highlighted the potential for AI to accelerate the design of potent biological agents. Jake Jordan of the Nuclear Threat Initiative warned that AI can help adversaries create proteins that evade detection and assist in scaling production and distribution of pathogens. He cited a recent Anthropic report showing users attempting to use the company’s model to improve the transmissibility of a lethal bird-flu virus.

In the defense sector, officials are pursuing rapid AI integration despite safety concerns. The U.S. Defense Secretary announced an “AI-first” transformation for the military, and the Pentagon’s budget request includes substantial funding to embed AI in command and control systems, including those related to nuclear weapons. Hamza Chaudhry of the Future of Life Institute cautioned that AI hallucinations in critical sensor networks could trigger unintended escalation.

California Governor Gavin Newsom issued an executive order to create a task force aimed at developing an AI “kill switch.” Meanwhile, industry leaders such as Anthropic CEO Dario Amodei have called for a slower development pace to allow safety teams to keep up with new capabilities.

Not all voices in the AI community share the same level of alarm. Keegan McBride of the Tony Blair Institute dismissed existential scenarios as overblown, while AI ethicist Timnit Gebru suggested that extreme warnings may distract from more immediate issues like data privacy and labor practices.
