The infinity machine – Sebastian Mallaby
Demis Hassabis has given Sebastian Mallaby a great deal of his time, sitting for over thirty hours of conversation. But Mallaby has also drawn from Hassabis’s detractors, such as his estranged cofounder Mustafa Suleyman; from his rivals, such as OpenAI’s leading scientist Ilya Sutskever; and from academic pioneers who now fear for human survival, such as Nobel laureate Geoffrey Hinton. The result is a revelatory account of a singular figure and his company and a profound reckoning with this protean field as it leaps from the periphery to the center of our consciousness.
No one questions Hassabis’s brilliance. There are those who, like Elon Musk, have at times regarded him as an “evil genius.” He is in a game where the stakes are matched only by the exorbitant costs — for talent, and for compute. Celebrated scientists pursue the technology because they cannot resist the sweetness of discovery. Others pursue it for money or power. The inventors believe they control their technology, but often, the technology controls them.
Despite Hassabis’s pivotal role inside Google’s engine room, this is not a Silicon Valley story. Hassabis deals with the Valley and takes its money, but remains outside and furiously critical of it, lambasting its leaders in conversation with Mallaby. The end of this race cannot be known, but as this great book shows us, Hassabis’s quest to will a new form of cognition into the world is a defining story for our era.
