As AI advances biothreats, defenses won't mature on their own, researcher warns

Kath McMahon argues that more capable models will bring increased biological risk—the magnitude is fiercely debated but the direction is not. Citing COVID's 7 million deaths and trillions in damage as a warning, she stresses that defenses cannot be assumed to mature in lockstep with rising risk; it takes dedicated people, policy, and development. She calls for racing to use AI advances to mitigate today's known natural threats and to build resilience for a new era of risk.
