There’s an epic struggle underway: a challenge to lead the world in artificial intelligence — AI. But this space race for the 21st century doesn’t seem to be getting enough attention from at least one of the world’s superpowers — the United States. In this featured episode from The World's partners at the podcast "Raw Data," futurist Amy Webb tells the story of the world’s leading AI companies, and the struggle between East and West in her new book, "The Big Nine: How the Tech Titans & Their Thinking Machines Could Warp Humanity." We learn about China’s growing dominance in AI, and how US companies, in spite of stunning technological innovation, might someday fall behind. What’s at stake is nothing less than the future of power, governance and freedom.
