Engineered Pandemics & Bioweapons
Advances in synthetic biology lower the barrier to creating novel pathogens. A deliberately engineered pandemic could kill hundreds of millions and destabilize civilization.
Scale of the Problem
The cost to sequence and synthesize dangerous pathogens has dropped 10,000x since 2000.
The 1918 influenza pandemic killed over 50 million people in a much smaller world. An engineered pathogen optimized for transmissibility and lethality could plausibly kill hundreds of millions or threaten civilization. Toby Ord estimates existential risk from engineered pandemics at roughly 3 percent this century, higher than from natural pandemics or nuclear war.
Why This Is Pressing
COVID-19 killed around 7 million people and cost trillions of dollars, yet it was not engineered and not worst-case. The tools to design more transmissible or more lethal pathogens are becoming cheaper and more accessible: DNA synthesis costs fall each year, gain-of-function research continues worldwide, and AI systems can now assist with protocol design and troubleshooting. Credible biosecurity experts estimate a meaningful probability of a catastrophic engineered pandemic this century. The next one could be deliberately released, could combine high transmissibility with high lethality, and could be much harder to contain with vaccines or natural immunity.
Why It's Neglected
Biosecurity funding is tiny relative to the scale of the risk. US Administration for Strategic Preparedness and Response biodefense spending is around 1.8 billion dollars per year, dwarfed by traditional defense budgets. Global philanthropic funding for catastrophic pandemic prevention is estimated at only a few hundred million dollars. Few organizations focus specifically on worst-case scenarios.
Can It Be Solved?
Concrete levers exist: pathogen-agnostic wastewater and metagenomic surveillance, broad-spectrum antivirals, next-generation PPE stockpiles, far-UVC lighting, DNA-synthesis screening, stronger Biological Weapons Convention enforcement, and improved lab biosafety. Some policy wins have been achieved, and promising technologies are ready to scale with more funding.
