Every few decades, a set of technologies arrives that fundamentally changes how business works. The steam engine did it. Electricity did it. The internet did it. And now, according to Andrew McAfee and Erik Brynjolfsson, we are living through another such moment. The authors of Machine, Platform, Crowd spent years studying how digital technologies transform companies, industries, and entire economies. Their previous work explored how automation was changing the workforce. This book goes deeper. It asks a more fundamental question: what happens to business when machines start making better decisions than humans, when platforms start beating products, and when the crowd starts outperforming the core? Most business books focus on one of these shifts. Some books tell you about artificial intelligence. Others explain the rise of platforms like Uber and Airbnb. Still others explore crowdsourcing and open innovation. What makes this book different is that McAfee and Brynjolfsson see these as three parts of the same story.

Financial analysts picked stocks. Managers made hiring calls. Expertise lived in human minds, and those minds were scarce and expensive. Then something changed. Computers got fast enough and data got abundant enough that machines started beating human experts at their own games. Not everywhere, not yet, but in a growing number of domains. And the machines keep getting better. At the same time, the economics of business shifted. For most of the industrial era, the path to success was building a great product and protecting it. Companies invested in factories, supply chains, and brands. But digital platforms changed the rules. A platform doesn't make the product. It connects people who have something with people who want something. And once a platform reaches critical mass, it becomes extraordinarily difficult to compete with. Finally, the boundary between what a company does internally and what it gets from outside has blurred. The "core" of a company used to be its employees, its proprietary knowledge,…
