Machines that are smarter than people? A utopian dream of science-fiction novelists and Hollywood screenwriters perhaps, but one which technological progress is turning into reality. Two trends are coming together: exponential growth in the processing power of supercomputers, and new software which can copy the way neurons in the human brain work and give machines the ability to learn. Smart systems will soon be commonplace in homes, businesses, factories, administrations, hospitals and the armed forces. How autonomous will they be? How free to make decisions? What place will human beings still have in a world controlled by robots? After the atom bomb, is artificial intelligence the second lethal weapon capable of destroying mankind, its inventor? The Fall of the Human Empire traces the little-known history of artificial intelligence from the standpoint of a robot called Lucy. She – or it? – recounts her adventures and reveals the mysteries of her long journey with humans, and provides a thought-provoking storyline of what developments in A.I. may mean for both humans and robots.

Empires and Barbarians presents a fresh, provocative look at how a recognizable Europe came into being in the first millennium AD. With sharp analytic insight, Peter Heather explores the dynamics of migration and social and economic interaction that changed two vastly different worlds--the undeveloped barbarian world and the sophisticated Roman Empire--into remarkably similar societies and states. The book's vivid narrative begins at the time of Christ, when the Mediterranean circle, newly united under the Romans, hosted a politically sophisticated, economically advanced, and culturally developed civilization--one with philosophy, banking, professional armies, literature, stunning architecture, even garbage collection. The rest of Europe, meanwhile, was home to subsistence farmers living in small groups, dominated largely by Germanic speakers. Although having some iron tools and weapons, these mostly illiterate peoples worked mainly in wood and never built in stone. The farther east one went, the simpler it became: fewer iron tools and ever less productive economies. And yet ten centuries later, from the Atlantic to the Urals, the European world had turned. Slavic speakers had largely superseded Germanic speakers in central and Eastern Europe, literacy was growing, Christianity had spread, and most fundamentally, Mediterranean supremacy was broken. Bringing the whole of first millennium European history together, and challenging current arguments that migration played but a tiny role in this unfolding narrative, Empires and Barbarians views the destruction of the ancient world order in light of modern migration and globalization patterns.

By the award-winning author of A (Very) Short History of Life on Earth: a history of humanity on the brink of decline. We are living through a period that is unique in human history. For the first time in more than ten thousand years, the rate of human population growth is slowing down. In the middle of this century population growth will stop, and the number of people on Earth will start to decline - fast. In this provocative book, award-winning science writer Henry Gee offers a concise, brilliantly-told history of our species--and argues that we are on a rapid, one-way trip to extinction. The Decline and Fall of the Human Empire narrates the dramatic rise of humanity, how a scattered range of small groups across several continents eventually inbred, interacted, fought, established stable communities and food supplies, and began the process of dominating the planet. The human story is relatively brief—the oldest fossils of H. Sapiens date to approximately 300,000 years ago—yet the spread of our species has been unstoppable...until recently. As Gee demonstrates, our population has peaked, and is declining; our environment is becoming inimical to human life in many locations; our core resources of water, arable land, and air are diminishing; and new diseases, simmering conflicts, and ambiguous technologies threaten our collective health. Can we still change our course? Or is our own extinction inevitable? There could be a way out, but the launch window is narrow. Unless Homo sapiens establishes successful colonies in space within the next two centuries, our species is likely to stay earthbound and will have vanished entirely within another ten thousand years, bringing the seven-million-year story of the human lineage to an end. With assured narration, dramatic stories, and his signature sprightly humor, Henry Gee envisions new opportunities for the future of humanity—a future that will reward facing challenges with ingenuity, foresight, and cooperation.

How devastating viruses, pandemics, and other natural catastrophes swept through the far-flung Roman Empire and helped to bring down one of the mightiest civilizations of the ancient world Here is the monumental retelling of one of the most consequential chapters of human history: the fall of the Roman Empire. The Fate of Rome is the first book to examine the catastrophic role that climate change and infectious diseases played in the collapse of Rome’s power—a story of nature’s triumph over human ambition. Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes readers from Rome’s pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted. Harper describes how the Romans were resilient in the face of enormous environmental stress, until the besieged empire could no longer withstand the combined challenges of a “little ice age” and recurrent outbreaks of bubonic plague. A poignant reflection on humanity’s intimate relationship with the environment, The Fate of Rome provides a sweeping account of how one of history’s greatest civilizations encountered and endured, yet ultimately succumbed to the cumulative burden of nature’s violence. The example of Rome is a timely reminder that climate change and germ evolution have shaped the world we inhabit—in ways that are surprising and profound.

What went wrong in imperial Rome, and how we can avoid it: “If you want to understand where America stands in the world today, read this.” —Thomas E. Ricks The rise and fall of ancient Rome has been on American minds since the beginning of our republic. Depending on who’s doing the talking, the history of Rome serves as either a triumphal call to action—or a dire warning of imminent collapse. In this “provocative and lively” book, Cullen Murphy points out that today we focus less on the Roman Republic than on the empire that took its place, and reveals a wide array of similarities between the two societies (The New York Times). Looking at the blinkered, insular culture of our capitals; the debilitating effect of bribery in public life; the paradoxical issue of borders; and the weakening of the body politic through various forms of privatization, Murphy persuasively argues that we most resemble Rome in the burgeoning corruption of our government and in our arrogant ignorance of the world outside—two things that must be changed if we are to avoid Rome’s fate. “Are We Rome? is just about a perfect book. . . . I wish every politician would spend an evening with this book.” —James Fallows
