President Donald Trump and Chinese President Xi Jinping discussed artificial intelligence during their White House summit but reached no breakthrough agreement on regulation, safeguards or development limits. Trump said he now prefers the term "superintelligence," or "SI," and that Xi liked the idea of changing the name. Trump said the United States was leading China by one or two years and would not put the brakes on development or expand cooperation. Xi said the two countries should ensure AI remains under human control. The summit included a state dinner attended by technology executives including Sam Altman, Elon Musk, Greg Brockman, Sundar Pichai, Jensen Huang, Tim Cook and Mark Zuckerberg. Earlier proposals for a bilateral AI dialogue and notification process for major national-security incidents were not formalized, while no changes to advanced semiconductor controls were announced.
