"If the spread of printing presses, combined with the spread of cheap hand-held mirrors, made available to millions of people a new sense of themselves as individuals, and as the authors of their own stories, which were inherently worth reading about and listening to, we can only wonder at the power inherent in billions of iPhones and other smartphone devices which combine a printing press, in the form of access to social media platforms, and a mirror, in the form of ever-more-powerful smartphone cameras, with which users endlessly record and broadcast selfies. Network billions of these mirrors together, and put them in real-time communication with each other, and it seems clear that we are looking at a species of transformative, technologically driven change that reaches deeper inside our heads and hearts and moves at a far greater velocity than anything human civilizations have ever experienced."
