"Google. Facebook. Twitter. Repeat. We live in a world unimaginable even a few decades ago, one like no other in human history. It's a parallel world where we can be on the move in the real world, yet always hooked into an alternative time and place. And although it's a two-dimensional world of sight and sound, it offers instant information, connected identities, and constant novelty. In this world, our screen technologies are increasingly where we work, where we unwind, where we relieve our boredom and where we learn. The subsequent transformation in how we live and think is a vitally important issue, perhaps even the most important issue of our time. When toddlers are given iPads, and adults spend ten hours a day staring at a screen, can we afford to assume that our brave new screen technologies are harmless tools? Blending a wide range of scientific studies, news events, and cultural criticism with brio and verve, Mind Change presents an incisive snapshot of the global 'now.' Greenfield examines how the dawn of the Digital Age has already altered our cultural landscape, fueled an epidemic of oversharing, and transformed how we learn, remember and spread information -- and how these innovations are changing our physical brains. A warning cry, a shot across the bow, and a call to action, Mind Change explores the social, cultural and physiological ramifications of our new digital lifestyle"--

An all-in-one guide to understanding and managing the dark side of our digital lives. It all started out so well: the online world began as an effective tool for communication that carried with it a great promise to level the playing field and eliminate borders. But it’s morphed into something totally unintended. We’ve all had to endure the troll that derails a generally benign conversation; or received that scam email from a wealthy Nigerian prince; or felt the strange feeling of being watched and tracked by advertising companies as we navigate the web. Welcome to the modern internet. These are but a few of the topics that The Dark Side of Our Digital World: And What You Can Do about It examines to get at the root causes of our current problems with information technology, social media, and problematic online behavior. The book explores the issues raised by the negative side of information technology, including surveillance and spying, declining privacy, information overload, surveillance capitalism and big data analytics, conspiracy theories and fake news, misinformation and disinformation, trolling and phishing. What’s ultimately at stake is how we are able to cope with increasingly invasive anti-social behaviors, the overall decline of privacy in the face of total surveillance technologies, and the lack of a quality online experience that doesn’t devolve into flame wars and insults. The future of the internet as well as our societies depends upon our ability to discern truth from lies and reality from propaganda. The book will therefore also examine the possible directions we could take to improve the situation, looking at solutions in the areas of psychology and behavioral conditioning, social engineering through nudging techniques, the development of e-democracy movements, and the implementation of public policy.

In these essays Heinz von Foerster discusses some of the fundamental principles that govern how we know the world and how we process the information from which we derive that knowledge. Included are path- breaking articles concerning the principles of computation in neural nets (1967), the definition of self-organizing systems (1960), the nature of cognition (1970), as well as recent expansions on these themes (e.g. "How recursive is communication," 1993). Working with Norbert Wiener, Warren McCullough, and others in the 1960s and 1970s, von Foerster was one of the founders of the science of cybernetics, which has had profound effects both on modern systems theory and on the philosophy of cognition. At the Biological Computer Laboratory at the University of Illinois he produced the first parallel computers and contributed to many other developments in the theory of computation and cognition.
