PHP creator Rasmus Lerdorf calls AI more dangerous than nukes

Rasmus Lerdorf, creator of the PHP programming language, has publicly characterized artificial intelligence as more dangerous than nuclear weapons in a statement shared via Bluesky. Lerdorf linked to an Associated Press article while asserting that AI risks exceed those of atomic weaponry, marking a significant intervention by a foundational figure in web development. The comment reflects growing alarm among veteran software engineers regarding the trajectory of advanced AI systems and their potential for catastrophic misuse or failure. Unlike nuclear arms, which require massive state infrastructure, AI capabilities are increasingly accessible and difficult to contain through traditional nonproliferation frameworks. Lerdorf’s stance aligns with a subset of technologists who argue that current safety measures are insufficient relative to the speed of capability advancement. Neither major AI laboratories nor government regulators have responded directly to his specific comparison. The statement adds to ongoing debates about whether AI development requires international treaty-level oversight similar to nuclear disarmament agreements.
