Hannah Critchlow, an author and neuroscientist at the University of Cambridge, begins this serious and impressive book with a bold assertion: our species is in the middle of a major transition, driven by a profound shift in our environment. Digital technology is now so pervasive, hyperconnected and powerful, she argues, that it has become the main driving force in our evolution – and our brains are going to have to adapt, quickly. Factor in artificial intelligence and it is clear the majority of humanity occupies an environment unlike any other in our 300-plus millennia of existence.
