From Nvidia to OpenAI, Silicon Valley woos Westminster as ex-politicians take tech firm roles

W hen the billionaire chief executive of AI chipmaker Nvidia threw a party in central London for Donald Trump's state visit in September, the power imbalance between Silicon Valley and British politicians was vividly exposed. Jensen Huang hastened to the stage after meetings at Chequers and rallied his hundreds of guests to cheer on the power of AI. In front of a huge Nvidia logo, he urged the venture capitalists before him to herald "a new industrial revolution", announced billions of pounds in AI investments and, like Willy Wonka handing out golden tickets, singled out some lucky recipients in the room. "If you want to get rich, this is where you want to be," he declared. But his biggest party trick was a surprise guest waiting in the wings.
