Time Magazine named “The Architects of AI” as their Person of the Year for 2025. This is a group of people, mostly men, who now wield an extraordinary level of influence over the future of society. The Media Show profiles four of them: Mike Isaac from The New York Times explains the rise of Sam Altman, the CEO of OpenAI; Lauren Goode from Wired outlines the power and beliefs of venture capitalist Marc Andreessen; Stephen Witt, biographer of Jensen Huang, describes how the Nvidia boss has built the chips powering modern AI; and Richard Spencer of The Times reports on DeepSeek founder Liang Wenfeng, whose work has challenged the dominance of US tech companies.
