Across the country, data centers that run A.I. programs are being constructed at a record pace. A large percentage of them use chips built by the tech colossus Nvidia. The company has nearly cornered the market on the hardware that runs much of A.I., and has been named the most valuable company in the world, by market capitalization. But Nvidia’s is not just a business story; it’s a story about the geopolitical and technological competition between the United States and China, about what the future will look like. In April, David Remnick spoke with Stephen Witt, who writes about technology for The New Yorker, about how Nvidia came to dominate the market, and about its co-founder and C.E.O., Jensen Huang. Witt’s book “The Thinking Machine: Jensen Huang, Nvidia, and the World’s Most Coveted Microchip” came out this year.
