Peter Lucas, Joe Ballay, and Mickey McManus are the authors of "Trillions", a new book about the future of the global economy. "Trillions" argues that we can't just design devices that help us to live better using data; rather, we have to design an entire living environment where those devices communicate with each other and with us. Only by building this interoperable network of humans and computers will we finally be able to exploit the massive potential of Big Data, and of ourselves.
