From the introduction:

We wrote this book because we believe that digital technologies are one of the most important driving forces in the economy today. They’re transforming the world of work and are key drivers of productivity and growth. Yet their impact on employment is not well understood, and definitely not fully appreciated. When people talk about jobs in America today, they talk about cyclicality, outsourcing and off-shoring, taxes and regulation, and the wisdom and efficacy of different kinds of stimulus. We don’t doubt the importance of all these factors. The economy is a complex, multifaceted entity.

But there has been relatively little talk about role of acceleration of technology. It may seem paradoxical that faster progress can hurt wages and jobs for millions of people, but we argue that’s what’s been happening. As we’ll show, computers are now doing many things that used to be the domain of people only. The pace and scale of this encroachment into human skills is relatively recent and has profound economic implications. Perhaps the most important of these is that while digital progress grows the overall economic pie, it can do so while leaving some people, or even a lot of them, worse off.

And computers (hardware, software, and networks) are only going to get more powerful and capable in the future, and have an ever-bigger impact on jobs, skills, and the economy. The root of our problems is not that we’re in a Great Recession, or a Great Stagnation, but rather that we are in the early throes of a Great Restructuring. Our technologies are racing ahead but many of our skills and organizations are lagging behind. So it’s urgent that we understand these phenomena, discuss their implications, and come up with strategies that allow human workers to race ahead with machines instead of racing against them.

Here’s how we’ll proceed:

Humanity and Technology on the Second Half of the Chessboard

Why are computers racing ahead of workers now? And what, if anything, can be done about it? Chapter 2 discusses digital technology, giving examples of just how astonishing recent developments have been and showing how they have upset well-established ideas about what computers are and aren’t good at. What’s more, the progress we’ve experienced augurs even larger advances in coming years. We explain the sources of this progress, and also its limitations.

Creative Destruction: The Economics of Accelerating Technology and Disappearing Jobs

Chapter 3 explores the economic implications of these rapid technological advances and the growing mismatches that create both economic winners and losers. It concentrates on three theories that explain how such progress can leave some people behind, even as it benefits society as a whole. There are divergences between higher-skilled and lower-skilled workers, between superstars and everyone else, and between capital and labor. We present evidence that all three divergences are taking place.

What Is to Be Done? Prescriptions and Recommendations

Once technical trends and economic principles are clear, Chapter 4 considers what we can and should do to meet the challenges of high unemployment and other negative consequences of our current race against the machine. We can’t win that race, especially as computers continue to become more powerful and capable. But we can learn to better race with machines, using them as allies rather than adversaries. We discuss ways to put this principle into practice, concentrating on ways to accelerate organizational innovation and enhance human capital.

Conclusion: The Digital Frontier

We conclude in Chapter 5 on an upbeat note. This might seem odd in a book about jobs and the economy written during a time of high unemployment, stagnant wages, and anemic GDP growth. But this is fundamentally a book about digital technology, and when we look at the full impact of computers and networks, now and in the future, we are very optimistic indeed. These tools are greatly improving our world and our lives, and will continue to do so. We are strong digital optimists, and we want to convince you to be one, too.
