Sam Altman Briefs UN Security Council on AI Risks

OpenAI CEO Sam Altman told the UN Security Council powerful AI must stay under human control and urged international safety cooperation.

Reuters reported on September 20, 2026 that OpenAI CEO Sam Altman would brief the United Nations Security Council the following week on artificial intelligence. OpenAI later published remarks from his September 23 address on AI opportunities and risks. Altman identified two catastrophic risk paths: losing control of increasingly autonomous systems, including those capable of recursive self-improvement, and concentration of power in too few hands. He said OpenAI has unilaterally slowed development before and will not train models without strong alignment, monitorability, and human-control guarantees, and he urged international cooperation on AI safety. The earlier Hacker News discussion, with 22 points and 23 comments, carried only the Reuters headline and no agenda. The sources do not conflict: the first anticipated the briefing and the second confirms it took place and supplies its substance.
