Once, it was conventional wisdom to assume that digital technologies would enable greater access to information, facilitate collective organizing, and empower civil society. Rather than facilitating unity and the emergence of a common ideology based on science, the internet and social media have proven to be vehicles used to spread falsehoods, pollute the public sphere, and subject populations to wholesale surveillance. People are also spending an unhealthy amount of time staring at their devices,socializing while in fact living in isolation and detached from nature. As a consequence, there are pushes to regulate social media and to encourage tech giants to be better stewards of their platforms, respect privacy, and acknowledge the role of human rights. A prerequisite of any such regulation, however, is a complete understanding of the precise nature and depth of the problems. Technology and security expert Ronald J. Deibert examines the scope and scale of the personal, social, political, economic, and ecological implications of social media. Drawing from the cutting-edge research of the Citizen Lab (which he directs), Deibert analyzes consumer compulsion and the information economy; the disturbing rise of authoritarian practices, cyberwarfare services, and social engineering campaigns; and the negative environmental impact of digital devices, data farms, and electronic waste. Ultimately, Deibert exposes social media's disproportionate influence in every aspect of life to the detriment of society and of our humanity--so much so that we are now in urgent need of a wholesale shift in our lifestyles, a fundamental revision of culture, work, and politics. And not just in one country, but around the world.
