Annie Jacobsen Warns of AI-Driven Bioweapons as New Book 'Biological War' Hits Shelves
Annie Jacobsen, the bestselling author of Nuclear War: A Scenario, is back in the spotlight with a new book, Biological War: A Scenario, published this week. The non-fiction thriller imagines a catastrophic lab leak from a Russian bioweapons facility, unleashing a genetically engineered plague with a 100% fatality rate. In parallel, Jacobsen has published a high-profile essay in The Guardian arguing that artificial intelligence is fueling both the threat of biological weapons and the tools to defend against them.
The timing is no coincidence. As AI rapidly transforms biological sciences, Jacobsen warns that the technology to engineer life is advancing faster than laws, treaties, and safeguards. In her Guardian op-ed, she writes: 'The offensive potential is no longer theoretical.' She calls for developing AI-driven detection and response systems to strengthen public health as quickly as AI accelerates biological design.
Her new book, praised as 'a page-turning thriller' by The Spectator, has already drawn comparisons to her 2024 nuclear war scenario. A former UK government adviser said it 'reads as a page-turning thriller' while also serving as 'a better briefing on the problem than the one we received in Downing Street.'
The Race Between Offense and Defense
Jacobsen's central argument is that we are in a race between two futures: one where bad actors use AI to generate recipes for biological weapons with a few keystrokes, and another where AI tracks outbreaks and delivers real-time public health information. The gap between these two futures is where existential danger lives.
Public health, she notes, wins by learning about an outbreak before it spreads widely. Every infectious disease outbreak begins with a handful of cases. AI's greatest value is compressing the timeline between outbreak and detection, potentially making the difference between containment and pandemic.
Her new book dramatizes the worst-case scenario: a genetically modified airborne bacterium as deadly as pneumonic plague, based on a real Soviet 'chimera program.' The engineered pathogen releases a second pathogen when treated, making it even more nightmarish. As former Senate Majority Leader Tom Daschle says in the book, biological war would be 'a long, painful, slow death… deeply nightmarish. People doing inhuman things, just to survive.'
AI as a Double-Edged Sword in Global Health
Jacobsen points to the World Health Organization's Hub for Pandemic and Epidemic Intelligence in Berlin as a model for AI-driven defense. The hub runs a system called Epidemic Intelligence from Open Sources, or Eios, which filters the world's minute-by-minute health information. Unlike traditional systems that rely on official case counts, Eios leverages social media, local news, and citizen reports to get an immediate picture of an outbreak.
This approach has already been used to track infectious disease outbreaks globally. The key is speed: as transmission rates explode, options shrink. AI's ability to analyze unofficial reports and chatter in real time could be the difference between stopping an outbreak early and facing a global crisis.
Yet the same computing power can be turned toward offense. Jacobsen warns that AI can help generate 'recipes for biological weapons' with minimal skill. The dual-use nature of AI in biology is a policy challenge that has yet to be met with adequate regulation.
The current news cycle, with Jacobsen's book and op-ed landing simultaneously, has reignited debate over biosecurity. Her work is a stark reminder that the tools to protect us and to harm us are advancing on the same exponential curve.
A Wake-Up Call for Policy and Science
Jacobsen's scenario is speculative, but her research is grounded in interviews with experts and declassified documents. She described Nuclear War: A Scenario as a plausible 72-minute nightmare; Biological War promises to be even more ghastly. The book's publication comes amid growing concern over lab safety and the potential for accidental or deliberate release of engineered pathogens.
For policymakers, the message is clear: the current framework of treaties and safeguards is outdated. AI is not just a tool; it is a multiplier of both risk and resilience. Jacobsen urges a Manhattan Project-style effort to develop AI defenses, similar to how the US marshaled science during World War II.
'We need to develop systems to strengthen public health as quickly as AI is accelerating biological design,' she writes. This means investing in surveillance, rapid diagnostics, and global collaboration.
As the world grapples with the implications of AI in many fields, Jacobsen's work is a timely and sobering look at one of the most consequential races of our era. Her book is already being compared to a thriller, but its real power lies in its warning. Whether we heed it is up to us.
