Story
Two leading data scientists offer an up-close and user-friendly look at artificial intelligence: what it is, how it works, where it came from and how to harness its power for a better world. Dozens of times per day, we all interact with intelligent machines that are constantly learning from the wealth of data now available to them. These machines, from smartphones to talking robots to self-driving cars, are remaking the world in the 21st century in the same way that the Industrial Revolution remade the world in the 19th.

If only there was a way to simplify our decision-making and problem-solving process and get satisfying, consistent results! The good news is, there is! Apply computer algorithms to your everyday problems.

Story
One of Michiko Kakutani's (New York Times) top 10 books of 2016. A funny thing happened on the way to the digital utopia. We've begun to fall back in love with the very analog goods and ideas the tech gurus insisted that we no longer needed. Businesses that once looked outdated, from film photography to brick-and-mortar retail, are now springing with new life. Notebooks, records, and stationery have become cool again.

Story
Technology affects every interaction, shapes our identities and constantly hijacks our attention. So how can we reclaim our power and feel less helpless at every stage of our lives? We speak as though technology is a powerful, unstoppable force and we are the victims. 'What is this technology doing to us?' we ask. But are we as helpless as we assume? Elaine Kasket connects the dots between our technology usage and the challenges it poses to our identity and development, and to our relationships and privacy.

Story
For decades, IBM shaped the way the world did business. IBM products were in every large organization, and IBM corporate culture established a management style that was imitated by companies around the globe. It was “Big Blue”—an icon. And yet over the years, IBM has gone through both failure and success. The company almost went out of business in the early 1990s, then came back strong with new business strategies and an emphasis on artificial intelligence. In this authoritative history, James Cortada tells the story of one of the most influential American companies of the last century.

Story
It used to be that to diagnose an illness, interpret legal documents, analyze foreign policy, or write a newspaper article you needed a human being with specific skills - and maybe an advanced degree or two. These days, high-level tasks are increasingly being handled by algorithms that can do precise work not only with speed but also with nuance. These "bots" started with human programming and logic, but now their reach extends beyond what their creators ever expected.

Story
This audiobook explains why AI is unique, what legal and ethical problems it could cause, and how we can address them. It argues that AI is unlike any other previous technology, owing to its ability to take decisions independently and unpredictably. This gives rise to three issues: responsibility - who is liable if AI causes harm; rights - the disputed moral and pragmatic grounds for granting AI legal personality; and the ethics surrounding the decision-making of AI.

Story
The word "glitch" implies an incidental error, as easy to patch up as it is to identify. But what if racism, sexism, and ableism aren't just bugs in mostly functional machinery—what if they're coded into the system itself? Meredith Broussard demonstrates in More Than a Glitch how neutrality in tech is a myth and why algorithms need to be held accountable. Broussard, a data scientist and one of the few Black female researchers in artificial intelligence, masterfully synthesizes concepts from computer science and sociology.

NASA’s history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America’s space agency wasn’t created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. Breaking the Chains of Gravity tells the story of America’s nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military.

As the host of The Michael Brooks Show and cohost of the Majority Report, Brooks was a progressive fighter whose work brought people together from around the world. In this, his first book, he lets his understanding of the digital media environment direct his analysis of the "conservative rebels" who had taken YouTube by storm in 2018. Brooks provides a theoretically rigorous but accessible critique of the most prominent "renegades," including Sam Harris, Jordan Peterson, and Brett Weinstein while also examining the social, political, and media environment that such rebels thrive in.

The bicycle is a vestige of the Victorian era, seemingly out of pace with our age of smartphones and ridesharing apps and driverless cars. Yet we live on a bicycle planet. Across the world, more people travel by bicycle than by any other form of transportation. Almost anyone can learn to ride a bike—and nearly everyone does. In Two Wheels Good, writer and critic Jody Rosen reshapes our understanding of this ubiquitous machine, an ever-present force in humanity's life and dreamlife, and a flashpoint in culture wars for more for than 200 years.

Starting with hands, abacus, and slide rule, humans have always reached for tools to simplify math. Pocket-sized calculators ushered in modern mathematics, helped build the atomic bomb, took us to the bottom of the ocean, and accompanied us to the moon. The pocket calculator changed our world, until it was supplanted by more modern devices that, in a cruel twist of irony, it helped to create. Keith Houston transports listeners from the nascent economies of the ancient world to World War II, and into the technological arms race that led to the first affordable electronic pocket calculators.

Story
In this witty, often terrifying work of cultural criticism, Postman chronicles our transformation into a Technopoly: a society that no longer merely uses technology as a support system but instead is shaped by it. According to Postman, technology is rapidly gaining sovereignty over social institutions and national life to become self-justifying, self-perpetuating, and omnipresent. He warns that this will have radical consequences for the meanings of politics, art, religion, family, education, and more.
