At the United Nations Security Council, the architects of some of the world's most powerful artificial intelligence systems made a rare and sobering appeal: they asked governments to constrain what they themselves had created. Sam Altman and Dario Amodei warned that AI's accelerating capabilities were outpacing humanity's capacity to govern them, and called for binding international standards. The United States declined, choosing strategic autonomy over shared rules — a decision that may define the shape of the global AI order for years to come.
