Now the phenomenon is about to affect the whole economy. A formidable new technology infrastructure — the Internet of Things — is emerging with the potential to push much of economic life to near zero marginal cost over the course of the next two decades. This new technology platform is beginning to connect everything and everyone. Today more than 11 billion sensors are attached to natural resources, production lines, the electricity grid, logistics networks and recycling flows, and implanted in homes, offices, stores and vehicles, feeding big data into the Internet of Things. By 2020, it is projected that at least 50 billion sensors will connect to it.

People can connect to the network and use big data, analytics and algorithms to accelerate efficiency and lower the marginal cost of producing and sharing a wide range of products and services to near zero, just as they now do with information goods. For example, 37 million buildings in the United States have been equipped with meters and sensors connected to the Internet of Things, providing real-time information on the usage and changing price of electricity on the transmission grid. This will eventually allow households and businesses that are generating and storing green electricity on-site from their solar and wind installations to program software to take them off the electricity grid when the price spikes so they can power their facilities with their own green electricity and share surplus with neighbors at near zero marginal cost.

Cisco forecasts that by 2022, the private sector productivity gains wrought by the Internet of Things will exceed $14 trillion. A General Electric study estimates that productivity advances from the Internet of Things could affect half the global economy by 2025.

THE unresolved question is, how will this economy of the future function when millions of people can make and share goods and services nearly free? The answer lies in the civil society, which consists of nonprofit organizations that attend to the things in life we make and share as a community. In dollar terms, the world of nonprofits is a powerful force. Nonprofit revenues grew at a robust rate of 41 percent — after adjusting for inflation — from 2000 to 2010, more than doubling the growth of gross domestic product, which increased by 16.4 percent during the same period. In 2012, the nonprofit sector in the United States accounted for 5.5 percent of G.D.P.

What makes the social commons more relevant today is that we are constructing an Internet of Things infrastructure that optimizes collaboration, universal access and inclusion, all of which are critical to the creation of social capital and the ushering in of a sharing economy. The Internet of Things is a game-changing platform that enables an emerging collaborative commons to flourish alongside the capitalist market.
