The story at a glance

A blue-sky thinker gazes toward artificial superintelligence, captivating Silicon Valley's godlike AI leaders. Demis Hassabis, co-founder and CEO of Google DeepMind, embodies this drive. The Economist reviews Sebastian Mallaby's fresh biography amid surging AI rivalry. It arrives as DeepMind cements leadership post-Nobel triumph.[[1]](https://www.economist.com/culture/2026/04/01/who-is-demis-hassabis-the-man-behind-google-deepmind)[[2]](https://www.goodreads.com/book/show/241434373-the-infinity-machine)

Key moments & milestones

1976: Born in North London to immigrant parents, emerges as chess prodigy by age four.[[3]](https://en.wikipedia.org/wiki/Demis_Hassabis)
1990s: Codes hit video game Theme Park at 17, spurns seven-figure offer for Cambridge studies.
2009: Earns neuroscience PhD at UCL, probing memory's link to imagination.
2010: Co-founds DeepMind to crack intelligence itself.
2014: Google acquires DeepMind, fuelling grand pursuits.
2016: AlphaGo vanquishes Go world champion.
2020: AlphaFold conquers 50-year protein-folding riddle.
2024: Shares Nobel Prize in Chemistry for computational biology leap.[[4]](https://www.penguin.co.uk/books/461432/the-infinity-machine-by-mallaby-sebastian/9780241703564)

Signature highlights

Born to a Greek-Cypriot father and Chinese-Singaporean mother in modest North London, Hassabis taught himself chess at four, hitting master level by 13 with a 2300 Elo—captaining England juniors yet quitting at 12, deeming such brilliance better spent elsewhere.[[3]](https://en.wikipedia.org/wiki/Demis_Hassabis)

His teenage wizardry shone in Theme Park, a multimillion-seller blending AI simulation and management; rejecting a seven-figure payday, he chased science at Cambridge, then fused computer science with neuroscience to mimic human learning's essence.

DeepMind's ethos—solve intelligence, then everything else—drew Elon Musk's early cash, birthing feats like AlphaGo's intuitive Move 37, defying experts, and AlphaFold's revolution in drug design by mapping life's molecular machinery.

Mallaby's access yields vivid tensions: Hassabis's clashes with Google over autonomy, his stealth AI trading experiments, and critiques that the book soft-pedals his edge in AI's cutthroat philosophies and models.

Key quotes

“Doing science is, sort of, like reading the mind of God.” — Demis Hassabis, to Sebastian Mallaby.[[5]](https://www.theguardian.com/books/2026/mar/16/the-infinity-machine-by-sebastian-mallaby-review-the-story-of-the-man-who-changed-the-world)

Why it matters

AI's race could remake reality, from curing diseases to unlocking physics' secrets—or unleash perils if unchecked. Decision-makers must grasp if singular geniuses like Hassabis can balance moonshot science against profit's pull. Watch DeepMind's AGI strides and regulatory clashes for abundance's dawn or disruption.
