Chris Anderson, former Wired magazine editor-in-chief and author of Makers: The New Industrial Revolution, describes what he calls the maker movement. According to Anderson, modern technologies, such as 3D printing and open source design, are democratizing manufacturing. The same disruption that digital technologies brought to information goods like music, movies and publishing will soon make its way to the world of physical goods, he says. Anderson tells the story of his grandfather, who designed the first automatic sprinkler system in the 60s, and how different such an invention story would be today. He also discusses his own firm, 3D Robotics, and policy challenges to emerging manufacturing technology.
