The instant New York Times bestseller.

From Microsoft's president and one of the tech industry's broadest thinkers, a frank and thoughtful reckoning with how to balance enormous promise and existential risk as the digitization of everything accelerates.

“A colorful and insightful insiders’ view of how technology is both empowering and threatening us. From privacy to cyberattacks, this timely book is a useful guide for how to navigate the digital future.” —Walter Isaacson

Microsoft President Brad Smith operates by a simple core belief: When your technology changes the world, you bear a responsibility to help address the world you have helped create. This might seem uncontroversial, but it flies in the face of a tech sector long obsessed with rapid growth and sometimes on disruption as an end in itself. While sweeping digital transformation holds great promise, we have reached an inflection point. The world has turned information technology into both a powerful tool and a formidable weapon, and new approaches are needed to manage an era defined by even more powerful inventions like artificial intelligence. Companies that create technology must accept greater responsibility for the future, and governments will need to regulate technology by moving faster and catching up with the pace of innovation.

In Tools and Weapons, Brad Smith and Carol Ann Browne bring us a captivating narrative from the cockpit of one of the world's largest and most powerful tech companies as it finds itself in the middle of some of the thorniest emerging issues of our time. These are challenges that come with no preexisting playbook, including privacy, cybercrime and cyberwar, social media, the moral conundrums of artificial intelligence, big tech's relationship to inequality, and the challenges for democracy, far and near. While in no way a self-glorifying "Microsoft memoir," the book pulls back the curtain remarkably wide onto some of the company's most crucial recent decision points as it strives to protect the hopes technology offers against the very real threats it also presents. There are huge ramifications for communities and countries, and Brad Smith provides a thoughtful and urgent contribution to that effort.
“A clear, compelling guide to some of the most pressing debates in technology today.”—Bill Gates, from the foreword
 
“‘When your technology changes the world,’ writes Smith, ‘you bear a responsibility to help address the world you have helped create.’ In Tools and Weapons, Smith and co-author Carol Ann Browne, make a persuasive, pragmatic case for owning that responsibility, in everything from digital privacy and surveillance to cybersecurity and social fragmentation to artificial intelligence and facial-recognition technology.” —Seattle Times 
 
“Casual readers who know Microsoft primarily for Windows, Office and maybe Xbox will be surprised by the level of insight Smith brings to some of the biggest issues facing not just the industry but humanity. [Tools and Weapons] is written for a mass market, not just tech and policy wonks. It offers a framework for everyday readers to understand and think about the implications of powerful new forms of technology. . . . It’s full of behind-the-scenes anecdotes, from internal Microsoft meetings to high-level sessions at the Obama and Trump White Houses. It makes ample use of historical references to put modern trends and technologies in context.” —GeekWire
 
“Smith’s book is not the typical vanity project churned out by so many Fortune 500 leaders, the generic tomes on leadership and teamwork stocked at airport bookstores near the neck pillows. Tools and Weapons is a glimpse behind the curtain as Microsoft reckoned with the Snowden revelations, defended against the vicious cyberattacks, and took both the Obama and Trump administrations to court.” —Rolling Stone

"Tools and Weapons reads like a techno-legal thriller, yet offers a thorough and eye-opening account of the major tech controversies of the last decade, from NSA spying through AI ethics and the US-China standoff. Brad Smith, a believer that "great power brings great responsibility" makes it evident that the future of humanity may depend on ethical and responsive leadership in the tech industries, and in this book he sets a high bar for his peers." —Tim Wu, author of The Curse of Bigness

“This is a colorful and insightful insiders’ view of how technology is both empowering and threatening us. From privacy to cyberattacks, this timely book is a useful guide for how to navigate the digital future.” —Walter Isaacson, bestselling author of The Innovators and Steve Jobs
 
“Perhaps more than any industry leader, Brad Smith understands that technology is a double-edged sword—unleashing incredible opportunity but raising profound questions about democracy, civil liberties, the future of work and international relations. Tools and Weapons tackles these and other questions in a brilliant and accessible manner. It is a timely book that should be read by anyone seeking to understand how we can take advantage of technology’s promise without sacrificing our freedom, privacy or security.” —Former Secretary of State Madeleine K. Albright
 
“With clarity and candor, Brad Smith and Carol Ann Browne have crafted an indispensable guide to understanding and tackling the mightiest tech challenges of our time. Drawing on firsthand experience as well as the lessons of history, this perceptive volume shows that solutions will not be solely governmental nor corporate, but must involve collaboration across sectors and borders. Timely, essential reading for all who care about where the tech world goes next.” —Margaret O’Mara, author of The Code
 
“Coming from an industry driven by disruption, it’s refreshing to read Brad Smith’s call for the tech sector to assume more responsibility. In Tools and Weapons, Brad and Carol Ann Browne wrestle with some of the world’s toughest technology challenges with common sense and valuable insight reflecting their inside experience. The ideas in Tools and Weapons won’t solve all our problems, but they’re a very good place to start.” —Reed Hastings, CEO, Netflix
 
“At a time when many leaders in tech want to avoid a discussion of the social, economic, and security ramifications of the products they’ve built, it’s refreshing to see Brad Smith step up, urge the industry to take action, and acknowledge the need for smart regulation. This book offers an excellent encapsulation of some of the biggest challenges facing technologists, policymakers, and users alike.” —Senator Mark Warner
 
“Brad Smith has emerged as a vocal and principled thought leader addressing how technology can either help uphold or undermine human rights. As digital technology continues to proliferate, these issues will only grow in importance and command more of the world’s attention.” —Amal Clooney, international human rights lawyer and co-founder and president, Clooney Foundation for Justice
