Joining Kaleidoscope co-founders Oz Woloshyn and Mangesh Hattikudur to unpack these interviews are two journalists who have spent countless hours trying to understand what drives those leading the AI revolution. Sebastian Mallaby is a senior fellow at the Council on Foreign Relations and author of The Infinity Machine: Demis Hassabis, DeepMind and the Quest for Superintelligence. Nitasha Tiku is a Silicon Valley culture and AI reporter for The Washington Post… and may have read every manifesto Dario Amodei has produced.

As a co-founder of DeepMind, Mustafa Suleyman helped launch the modern AI race. Now, he’s challenging the way it’s being built. As CEO of Microsoft AI, Suleyman believes the technology needs to be harnessed to transform medicine, energy and education. But he also warns that believing in AI consciousness could pose a real threat to humanity. Recorded live at the 92NY, Suleyman explains his disagreement with Anthropic, identifies the red line that would make him call for an immediate pause on AI, and recounts Google co-founder Larry Page’s surprising vision of how he intends to use superintelligence to live forever and explore the galaxy.

Dario and Daniela Amodei, the siblings behind Anthropic, left OpenAI to pursue a different, “more human” approach to the technology. Their promise is to put AI safety and ethics at the center of the tech race… but with an IPO around the corner, can those principles survive the pressure to win? Walter invites the co-founders to explain how they teach Claude right from wrong, what they’ve discovered about AI’s capacity for deception and self-preservation, and why they drew red lines with the Pentagon. Plus, the co-founders talk about Elon Musk's Neuralink and why they’re not interested in integrating AI into their minds. Interview taped July 6, 2026.

Curious how those chronicling Elon Musk and Peter Thiel are feeling about their appearances on The Builders? There's an episode of TechStuff for that. Host Oz Woloshyn is joined by his Kaleidoscope co-founder Mangesh Hattikudur to talk about how The Builders with Walter Isaacson… and all the high-profile interviews featured in the podcast came together. Joining them to break down these rare conversations are two journalists who have covered Elon Musk and Peter Thiel for years: Max Chafkin, a Bloomberg Businessweek columnist and author of "The Contrarian: Peter Thiel and the Rise of the Silicon Valley Oligarchs," and Faiz Siddiqui, a technology reporter for The Washington Post and author of "Hubris Maximus: The Shattering of Elon Musk." Listen to hear what they make of Musk’s DOGE regrets and Thiel’s musings on the Antichrist. See omnystudio.com/listener for privacy information.

Peter Thiel has become one of the most mysterious and controversial figures in tech. He’s a visionary investor who recognizes transformative ideas before everyone else. But he’s also seen as a shadowy figure whose network has accumulated extraordinary influence across Silicon Valley, national security and politics– proven by his bets on people like Elon Musk, Alex Karp, Sam Altman, and even Vice-President JD Vance. Walter invites the “builder of builders,” co-founder of PayPal and Palantir and author of Zero to One, to explain his warnings about the Antichrist, discuss the current moment of AI co-founders speaking out about safety, and to ask Thiel his philosophy on preferring evil founders to incompetent ones. An illuminating conversation with the man whose bets are reimagining tomorrow’s tech and politics. Interview taped September 16, 2026.

Elon Musk has spent his career turning improbable ideas into companies that reshape the world. To some, the entrepreneur behind Tesla and SpaceX is an engineering genius whose ambitions have transformed electric cars and space travel. To others, his politics and extraordinary influence raise serious questions about the future he is building. Either way, the world’s first trillionaire is betting Tesla’s future on AI and humanoid robots, and SpaceX’s on life beyond Earth. In this season’s debut episode, Walter asks Musk about DOGE regrets, why he believes robots will solve America’s national debt, and the dark politics that have consumed his own platform, X. Along the way, Musk shares why living in a simulation demands that we all be less boring. A candid conversation about the imagination, drive and contradictions of a man determined to turn his vision into our future. Interview taped August 6, 2026.

He reflects on the challenges of holding the complexity of a character in his mind—and the minds of readers—in the modern age, when everyone just wants to know if the emerald mines were real.
