MI5 Chief Warns AI Could Enable Terrorist Bioweapons, Novel Pathogens

MI5 Director General Ken McCallum warned that AI could lower barriers for terrorists to access biological weapons or generate novel pathogens if security measures fail. The statement reflects growing concern among Western intelligence agencies about AI-enabled biothreats, though it is a warning rather than evidence of an imminent attack. This matters as it signals potential shifts in threat assessment and counterterrorism priorities.
