Ways of Being: Animals, Plants, Machines: The Search for a Planetary Intelligence
by James BridleArtist, technologist, and philosopher James Bridle’s Ways of Being is a brilliant, searching exploration of different kinds of intelligence—plant, animal, human, artificial—and how they transform our understanding of humans’ place in the cosmos.What does it mean to be intelligent? Is it something unique to humans, or shared with other beings—beings of flesh, wood, stone, and silicon? The last few years have seen rapid advances in “artificial” intelligence. But as it approaches, it also gets weirder: rather than a friend or helpmate, AI increasingly appears as something stranger than we ever imagined, an alien invention that threatens to decenter and supplant us. At the same time, we’re only just becoming aware of the other intelligences which have been with us all along, even if we’ve failed to recognize or acknowledge them. These others—the animals, plants, and natural systems that surround us are slowly revealing their complexity, agency, and knowledge, just as the technologies we’ve built to sustain ourselves are threatening to cause their extinction, and ours. What can we learn from them, and how can we change ourselves, our technologies, our societies, and our politics, to live better and more equitably with one another and the non-human world?Artist and maverick thinker James Bridle drawn on biology and physics, computation, literature, art, and philosophy, to answer these unsettling questions. Startling and bold, Ways of Being explores the fascinating, strange and multitudinous forms of knowing, doing, and being which are becoming evident in the present, and which are essential for our survival.Includes illustrations

We Are Anonymous: Inside the Hacker World of LulzSec, Anonymous, and the Global Cyber Insurgency
by Parmy OlsonA thrilling, exclusive expose of the hacker collectives Anonymous and LulzSec. WE ARE ANONYMOUS is the first full account of how a loosely assembled group of hackers scattered across the globe formed a new kind of insurgency, seized headlines, and tortured the feds-and the ultimate betrayal that would eventually bring them down. Parmy Olson goes behind the headlines and into the world of Anonymous and LulzSec with unprecedented access, drawing upon hundreds of conversations with the hackers themselves, including exclusive interviews with all six core members of LulzSec. In late 2010, thousands of hacktivists joined a mass digital assault on the websites of VISA, MasterCard, and PayPal to protest their treatment of WikiLeaks. Other targets were wide ranging-the websites of corporations from Sony Entertainment and Fox to the Vatican and the Church of Scientology were hacked, defaced, and embarrassed-and the message was that no one was safe. Thousands of user accounts from pornography websites were released, exposing government employees and military personnel.Although some attacks were perpetrated by masses of users who were rallied on the message boards of 4Chan, many others were masterminded by a small, tight-knit group of hackers who formed a splinter group of Anonymous called LulzSec. The legend of Anonymous and LulzSec grew in the wake of each ambitious hack. But how were they penetrating intricate corporate security systems? Were they anarchists or activists? Teams or lone wolves? A cabal of skilled hackers or a disorganized bunch of kids?WE ARE ANONYMOUS delves deep into the internet's underbelly to tell the incredible full story of the global cyber insurgency movement, and its implications for the future of computer security.

We Just Build Hammers: Stories from the Past, Present, and Future of Responsible Tech
by Coraline Ada EhmkePhilosopher Noam Chomsky is famously quoted as saying that technology is neither good nor bad, but simply a neutral tool. He likens it to a hammer, which can be used by carpenters and torturers alike. While the neutrality of tech is an idea that appeals to many technologists, this perspective is out of alignment with today's realities of pervasive ad-tech, surveillance capitalism, algorithmic manipulation, and rising techno-fascism. We Just Build Hammers applies a lens of speculative and science fiction to connect you with a historical lineage of thinkers and activists in the responsible tech movement. Its narrative spans a century of major technological upheavals: from the advent of the atomic age to the formative years of computing; from the hacker visionaries of the turn of the century to the tech justice revolutionaries of today. This book challenges technologists to consider for themselves whether they're really just "building hammers"– technologies whose potential for good balances their potential for harm– or if they are unwittingly contributing to systems that exacerbate inequality, inequity, and injustice. What You Will Learn A historic grounding and a science fiction perspective to help untangle the difficult and fraught topic of tech ethics Ways to bring ethical considerations into the development of new technologies How to navigate the increasing complexity of the techno-social world we live and work in Who This Book is For Designed to appeal broadly, not just to engineers and technologists, but to anyone interested in the history and future of ethics and technology.

We See It All: Liberty and Justice in an Age of Perpetual Surveillance
by Jon FasmanAn investigation into the legal, political, and moral issues surrounding how the police and justice system use surveillance technology, asking the question: what are citizens of a free country willing to tolerate in the name of public safety?As we rethink the scope of police power, Jon Fasman&’s chilling examination of how the police and the justice system use the unparalleled power of surveillance technology—how it affects privacy, liberty, and civil rights—becomes more urgent by the day. Embedding himself within police departments on both coasts, Fasman explores the moral, legal, and political questions posed by these techniques and tools.By zeroing in on how facial recognition, automatic license-plate readers, drones, predictive algorithms, and encryption affect us personally, Fasman vividly illustrates what is at stake and explains how to think through issues of privacy rights, civil liberties, and public safety. How do these technologies impact how police operate in our society? How should archaic privacy laws written for an obsolete era—that of the landline and postbox—be updated?Fasman looks closely at what can happen when surveillance technologies are combined and put in the hands of governments with scant regard for citizens&’ civil liberties, pushing us to ask: Is our democratic culture strong enough to stop us from turning into China, with its architecture of control?
