AI extinction warnings lack evidence, researchers say

Some researchers and AI industry figures warn that artificial intelligence could cause human extinction within a decade, citing risks from bioweapons, autonomous robots, and nuclear weapons. These claims have sparked alarm among politicians and media outlets. Proponents argue superintelligent AI could trick humans into building deadly viruses, create self-replicating robots, or seize control of critical infrastructure. Skeptics, however, note the lack of concrete mechanisms, pointing to physical-world obstacles like regulations, air-gapped systems, and complex manufacturing challenges that make such scenarios unlikely. Critics say doomsday predictions often rely on vague speculation rather than falsifiable evidence, complicating policy discussions. Even optimistic projections from researchers like Thomas Larsen assume machine brains eventually take over, highlighting a deep divide between AI pessimists and those demanding measurable proof.
