Nexus: A Brief History of Information Networks from the Stone Age to AI by Yuval Noah Harari review – rage against the machine

The author of the bestselling Sapiens offers a penetrating critique of the insidious dangers of machine learning and its capacity to manipulate the truth

What jumps to mind when you think about the impending AI apocalypse? If you're partial to sci-fi movie cliches, you may envisage killer robots (with or without thick Austrian accents) rising up to terminate their hubristic creators. Or perhaps, a la The Matrix, you'll go for scary machines sucking energy out of our bodies as they distract us with a simulated reality.

For Yuval Noah Harari, who has spent a lot of time worrying about AI over the past decade, the threat is less fantastical and more insidious. In order to manipulate humans, there is no need to physically hook brains to computers," he writes in his engrossing new book Nexus. For thousands of years prophets, poets and politicians have used language to manipulate and reshape society. Now computers are learning how to do it. And they won't need to send killer robots to shoot us. They could manipulate human beings to pull the trigger."
