    Infrastructure engineers use a software version of this “chaos monkey” to test online services’ robustness—their ability to survive random failure and correct mistakes before they actually occur. Tech entrepreneurs are society’s chaos monkeys, disruptors testing and transforming every aspect of our lives, from transportation (Uber) and lodging (AirBnB) to television (Netflix) and dating (Tinder). One of Silicon Valley’s most audacious chaos monkeys is Antonio García Martínez.After stints on Wall Street and as CEO of his own startup, García Martínez joined Facebook’s nascent advertising team, turning its users’ data into profit for COO Sheryl Sandberg and chairman and CEO Mark “Zuck” Zuckerberg. Forced out in the wake of an internal product war over the future of the company’s monetization strategy, García Martínez eventually landed at rival Twitter. He also fathered two children with a woman he barely knew, committed lewd acts and brewed illegal beer on the Facebook campus (accidentally flooding Zuckerberg's desk), lived on a sailboat, raced sport cars on the 101, and enthusiastically pursued the life of an overpaid Silicon Valley wastrel.Now, this gleeful contrarian unravels the chaotic evolution of social media and online marketing and reveals how it is invading our lives and shaping our future. Weighing in on everything from startups and credit derivatives to Big Brother and data tracking, social media monetization and digital “privacy,” García Martínez shares his scathing observations and outrageous antics, taking us on a humorous, subversive tour of the fascinatingly insular tech industry. Chaos Monkeys lays bare the hijinks, trade secrets, and power plays of the visionaries, grunts, sociopaths, opportunists, accidental tourists, and money cowboys who are revolutionizing our world. The question is, will we survive?

    We use social media as a mirror to decipher our place in society but, as Chris Bail explains, it functions more like a prism that distorts our identities, empowers status-seeking extremists, and renders moderates all but invisible. Breaking the Social Media Prism challenges common myths about echo chambers, foreign misinformation campaigns, and radicalizing algorithms, revealing that the solution to political tribalism lies deep inside ourselves.Drawing on innovative online experiments and in-depth interviews with social media users from across the political spectrum, this book explains why stepping outside of our echo chambers can make us more polarized, not less. Bail takes you inside the minds of online extremists through vivid narratives that trace their lives on the platforms and off--detailing how they dominate public discourse at the expense of the moderate majority. Wherever you stand on the spectrum of user behavior and political opinion, he offers fresh solutions to counter political tribalism from the bottom up and the top down. He introduces new apps and bots to help readers avoid misperceptions and engage in better conversations with the other side. Finally, he explores what the virtual public square might look like if we could hit reset and redesign social media from scratch through a first-of-its-kind experiment on a new social media platform built for scientific research.Providing data-driven recommendations for strengthening our social media connections, Breaking the Social Media Prism shows how to combat online polarization without deleting our accounts.

    This change is being driven by powerful new cognitive tools, enabled by the internet, which are greatly accelerating scientific discovery. There are many books about how the internet is changing business or the workplace or government. But this is the first book about something much more fundamental: how the internet is transforming the nature of our collective intelligence and how we understand the world.Reinventing Discovery tells the exciting story of an unprecedented new era of networked science. We learn, for example, how mathematicians in the Polymath Project are spontaneously coming together to collaborate online, tackling and rapidly demolishing previously unsolved problems. We learn how 250,000 amateur astronomers are working together in a project called Galaxy Zoo to understand the large-scale structure of the Universe, and how they are making astonishing discoveries, including an entirely new kind of galaxy. These efforts are just a small part of the larger story told in this book--the story of how scientists are using the internet to dramatically expand our problem-solving ability and increase our combined brainpower.This is a book for anyone who wants to understand how the online world is revolutionizing scientific discovery today--and why the revolution is just beginning.

    Then he wrote a groundbreaking operating system and distributed it via the Internet -- for free. Today Torvalds is an international folk hero. And his creation LINUX is used by over 12 million people as well as by companies such as IBM.Now, in a narrative that zips along with the speed of e-mail, Torvalds gives a history of his renegade software while candidly revealing the quirky mind of a genius. The result is an engrossing portrayal of a man with a revolutionary vision, who challenges our values and may change our world.

    In this brilliant study (his best-known and most controversial), he opposes the Marxist concept of dialectical materialism and its view that change takes place through "the struggle of opposites." Instead, he relates the rise of a capitalist economy to the Puritan determination to work out anxiety over salvation or damnation by performing good deeds — an effort that ultimately discouraged belief in predestination and encouraged capitalism. Weber's classic study has long been required reading in college and advanced high school social studies classrooms.

    Now he broadens the warning: the entire human game, he suggests, has begun to play itself out.Bill McKibben’s groundbreaking book The End of Nature -- issued in dozens of languages and long regarded as a classic -- was the first book to alert us to global warming. But the danger is broader than that: even as climate change shrinks the space where our civilization can exist, new technologies like artificial intelligence and robotics threaten to bleach away the variety of human experience.Falter tells the story of these converging trends and of the ideological fervor that keeps us from bringing them under control. And then, drawing on McKibben’s experience in building 350.org, the first truly global citizens movement to combat climate change, it offers some possible ways out of the trap. We’re at a bleak moment in human history -- and we’ll either confront that bleakness or watch the civilization our forebears built slip away.Falter is a powerful and sobering call to arms, to save not only our planet but also our humanity.

    Born in the mid-1990s to the mid-2000s and later, iGen is the first generation to spend their entire adolescence in the age of the smartphone. With social media and texting replacing other activities, iGen spends less time with their friends in person—perhaps why they are experiencing unprecedented levels of anxiety, depression, and loneliness. But technology is not the only thing that makes iGen distinct from every generation before them; they are also different in how they spend their time, how they behave, and in their attitudes toward religion, sexuality, and politics. They socialize in completely new ways, reject once sacred social taboos, and want different things from their lives and careers. More than previous generations, they are obsessed with safety, focused on tolerance, and have no patience for inequality. iGen is also growing up more slowly than previous generations: eighteen-year-olds look and act like fifteen-year-olds used to. As this new group of young people grows into adulthood, we all need to understand them: Friends and family need to look out for them; businesses must figure out how to recruit them and sell to them; colleges and universities must know how to educate and guide them. And members of iGen also need to understand themselves as they communicate with their elders and explain their views to their older peers. Because where iGen goes, so goes our nation—and the world.

    These three Great Untruths are part of a larger philosophy that sees young people as fragile creatures who must be protected and supervised by adults. But despite the good intentions of the adults who impart them, the Great Untruths are harming kids by teaching them the opposite of ancient wisdom and the opposite of modern psychological findings on grit, growth, and antifragility. The result is rising rates of depression and anxiety, along with endless stories of college campuses torn apart by moralistic divisions and mutual recriminations. This is a book about how we got here. First Amendment expert Greg Lukianoff and social psychologist Jonathan Haidt take us on a tour of the social trends stretching back to the 1980s that have produced the confusion and conflict on campus today, including the loss of unsupervised play time and the birth of social media, all during a time of rising political polarization. This is a book about how to fix the mess. The culture of “safety” and its intolerance of opposing viewpoints has left many young people anxious and unprepared for adult life, with devastating consequences for them, for their parents, for the companies that will soon hire them, and for a democracy that is already pushed to the brink of violence over its growing political divisions. Lukianoff and Haidt offer a comprehensive set of reforms that will strengthen young people and institutions, allowing us all to reap the benefits of diversity, including viewpoint diversity. This is a book for anyone who is confused by what’s happening on college campuses today, or has children, or is concerned about the growing inability of Americans to live and work and cooperate across party lines.

    Writing in venues like the New Republic and Commentary, such intellectuals were always expected to opine on a broad array of topics, from foreign policy to literature to economics. Yet in recent years a new kind of thinker has supplanted that archetype: the thought leader. Equipped with one big idea, thought leaders focus their energies on TED talks rather than highbrow periodicals. How did this shift happen? In The Ideas Industry, Daniel W. Drezner points to the roles of political polarization, heightened inequality, and eroding trust in authority as ushering in the change. In contrast to public intellectuals, thought leaders gain fame as single-idea merchants. Their ideas are often laudable and highly ambitious: ending global poverty by 2025, for example. But instead of a class composed of university professors and freelance intellectuals debating in highbrow magazines, thought leaders often work through institutions that are closed to the public. They are more immune to criticism--and in this century, the criticism of public intellectuals also counts for less.Three equally important factors that have reshaped the world of ideas have been waning trust in expertise, increasing political polarization and plutocracy. The erosion of trust has lowered the barriers to entry in the marketplace of ideas. Thought leaders don't need doctorates or fellowships to advance their arguments. Polarization is hardly a new phenomenon in the world of ideas, but in contrast to their predecessors, today's intellectuals are more likely to enjoy the support of ideologically friendly private funders and be housed in ideologically-driven think tanks. Increasing inequality as a key driver of this shift: more than ever before, contemporary plutocrats fund intellectuals and idea factories that generate arguments that align with their own. But, while there are certainly some downsides to the contemporary ideas industry, Drezner argues that it is very good at broadcasting ideas widely and reaching large audiences of people hungry for new thinking. Both fair-minded and trenchant, The Ideas Industry will reshape our understanding of contemporary public intellectual life in America and the West.

    In The Enigma of Capital, he delivers an impassioned account of how unchecked neoliberalism produced the system-wide crisis that now engulfs the world. Beginning in the 1970s, profitability pressures led the capitalist class in advanced countries to shift away from investment in industrial production at home toward the higher returns that financial products promised. Accompanying this was a shift towards privatization, an absolute decline in the bargaining power of labor, and the dispersion of production throughout the developing world. The decades-long and ongoing decline in wages that accompanied this turn produced a dilemma: how can goods--especially real estate--sell at the same rate as before if workers are making less in relative terms? The answer was a huge expansion of credit that fueled the explosive growth of both the financial industry and the real estate market. When one key market collapsed--real estate--the other one did as well, and social devastation resulted. Harvey places today's crisis in the broadest possible context: the historical development of global capitalism itself from the industrial era onward. Moving deftly between this history and the unfolding of the current crisis, he concentrates on how such crises both devastate workers and create openings for challenging the system's legitimacy. The battle now will be between the still-powerful forces that want to reconstitute the system of yesterday and those that want to replace it with one that prizes social justice and economic equality. The new afterword focuses on the continuing impact of the crisis and the response to it in 2010.
