In his annual address on threats to the nation, Sir Ken McCallum, director general of MI5, warned that advances in artificial intelligence could "change the stakes" in relation to existing and new biological weapons. His comments framed AI not only as a driver of economic and social change but also as a force with implications for national and global security.
Ian Sample, reporting for The Guardian, spoke to Dr Tom Inglesby, director of the Johns Hopkins Center for Health Security and a senior figure at the Bloomberg School of Public Health, to unpack the intelligence chief's warning. Inglesby laid out why the intersection of AI and the life sciences has become a focus for policymakers and security services.
Inglesby described the concerns prompting governments to pay closer attention to the issue. He said that recent technological developments have generated scenarios that could alter how biological threats emerge and are managed, and he emphasized that understanding those pathways is central to shaping policy responses.
On potential responses, Inglesby discussed a range of measures that could reduce risk. He highlighted the need for stronger safeguards, updated oversight of relevant research and technologies, and enhanced preparedness across public-health and security agencies. International coordination and information‑sharing were also presented as important elements in any comprehensive approach.
The conversation between Sample and Inglesby aimed to clarify both the nature of the risks identified by intelligence authorities and the policy options available to limit harm. It underscores a growing effort among security and health communities to assess and address how rapid advances in AI might interact with biological science and public‑health systems.
