Now What?

A guide to rethinking business in the digital age.

Andrew McAfee and Erik Brynjolfsson’s best-selling 2014 book, The Second Machine Age, explores how digital technology is transforming, and in many ways upending, our economy and our lives. Readers’ strong reactions to that book started the two cofounders of MIT’s Initiative on the Digital Economy (IDE) on the path toward their latest collaboration, Machine, Platform, Crowd: Harnessing Our Digital Future.

Brynjolfsson, IDE’s director and a Sloan professor, says they heard from fans of the previous book, “You made your case; we believe you. Now what do we do?” He adds, “We felt a responsibility to try to answer that question.”

In Machine, Platform, Crowd, he and McAfee, IDE’s co-director and a principal research scientist at Sloan, examine three trends changing business. First, they look at how our minds and ever-improving machines might work together to alter business processes. Second, they address the shifting relationship between products and the platforms consumers use to access them (paying particular attention to companies with few physical assets, such as Airbnb, a rental company that owns no properties, and Uber, a ride service that owns no cars). The third section explores how a company accustomed to relying on its own core processes and expertise can benefit from the knowledge of the crowd (as when GE launched an online campaign to solicit ideas for an innovative ice machine, getting valuable marketing data in the process).

The authors include questions designed to spur discussion and, they hope, action among organization leaders. “It’s not a cookbook, and it’s not step-by-step instructions,” says Brynjolfsson. “It provides the frameworks and intellectual understanding of how these factors relate together so that people can make intelligent decisions on their own.” He says this approach is especially relevant at a time of rapid change: “Part of what drove us was that we see so many things happening not just in terms of technology but also in terms of business models, but they are kind of chaotic. How do you make sense of these billion-dollar companies coming out of nowhere, and other billion-dollar companies going out of business, and people giving away products for free and becoming very wealthy, and other people struggling to find work?” While it can seem that there’s no rhyme or reason to what’s going on, he says that “if you have the right frameworks, a lot of this just makes a lot of sense.”

The coauthors’ collaboration is “incredibly smooth,” says McAfee—“We usually finish each other’s sentences”—but they also find that their occasional intellectual disagreements strengthen their work. When their points of view differ, “we spend some time hashing it out and trying to convince each other,” ­Brynjolfsson says. That process often leads them both to a third position.

Says McAfee: “When we think about something differently, that’s when things get really interesting.”
