## Summary

Sir Ken McCallum, head of the UK’s MI5, said AI could shift the potential risks of bioweapons in his annual threat assessment. Experts cited by *The Guardian* suggest AI could assist terrorists and nation-states in designing or producing biological threats, but major technical and ethical barriers remain.

The warning follows broader concerns about AI’s dual-use potential. While AI tools could theoretically accelerate research into pathogens or toxins, current capabilities are limited by accuracy, scalability, and the need for specialized biological expertise. McCallum’s statement highlights the need for vigilance without overstating AI’s immediate threat level.

## Key points

- MI5 head Sir Ken McCallum warns AI may ‘change the stakes’ in bioweapons development
- Experts say AI could aid terrorists or states but hurdles like accuracy and expertise persist
- No confirmed cases of AI-assisted bioweapons exist; warning is speculative and precautionary

## Why it matters

AI’s role in bioweapons risks could prompt stricter oversight, research funding shifts, and public awareness campaigns about dual-use threats.
