5 min readThe Prepared Mind: Sebastian Mallaby on Demis Hassabis, DeepMind, and the Race to Superintelligence
In early November 2022, Sebastian Mallaby pitched Demis Hassabis on writing a biography of him. A few weeks later, ChatGPT launched, and what had felt like a fringe subject to Mallaby suddenly became the center of global conversation. Mallaby, a two-time Pulitzer finalist and author of More Money Than God and The Power Law, had been tracking Hassabis for years—watching him take the stage at tech conferences, delivering sweeping talks spanning computer science, neuroscience, biology, philosophy, and film, all while looking like an unintimidating guy next door. That combination of approachability and massive intellect, paired with DeepMind's breakthroughs like AlphaGo and AlphaFold, gave Mallaby both a compelling subject and a compelling personality. The result is The Infinity Machine, a book that traces Hassabis's quest for artificial general intelligence (AGI) and the ecosystem that grew up around it.

What you'll learn
- 1 (04:22) **The Genesis of *The Infinity Machine*** - Sebastian describes how Demis Hassabis’s mixture of approachability and massive intellect first caught his attention, and how the concept of an “infinity machine” (AI systems that can understand near-infinite search spaces like Go or protein folding) became the book’s core idea.
- 2 (10:10) **The Religion of AI** - Sebastian explains why AI insiders naturally reach for religious terminology to describe something so powerful and mysterious.
- 3 (19:24) **Where Sebastian Lands on AI Promises vs. Perils** - He argues the only rational response is to be both excited and frightened.
- 4 (24:38) **Government Intervention and the Anthropic Case Study** - Sebastian discusses the inevitability of government control over frontier AI and the bull/bear case for Anthropic.
- 5 (33:27) **Where Sebastian Differs from Benedict Evans** - Sebastian agrees with Benedict’s view that short-term pain doesn’t negate long-term promise, but disagrees on whether foundation models will become commodities.
- 6 (42:04) **Who Wins the Consumer AI Race?** - Sebastian bets on Google (Gemini) because of its massive distribution advantage and the surprising resilience of its search advertising business.
- 7 (44:48) **What Sebastian Learned from China** - He was surprised by how much Chinese AI leaders brought up AI safety unprompted, contradicting the Biden administration’s assumption that they don’t care.
