In a laboratory at the intersection of computation and biology, researchers at Stanford and the Broad Institute have crossed a threshold that cannot be uncrossed: artificial intelligence has designed viruses that nature never made, and some of them work better than the real thing. The achievement promises new weapons against antibiotic-resistant bacteria, but it also demonstrates a capability whose implications extend far beyond any single experiment. Humanity has long wrestled with the dual nature of powerful tools; this moment asks whether our institutions of oversight can evolve as quickly
