Over the last few years, the Board and staff of the MacArthur Foundation have been exploring the implications of the digital age. They are engaged in a continuous and purposeful meditation on technological innovations and their possibilities for all the work they do. Their working hypothesis is that the digital revolution will rank with the invention of the printing press, the telephone, and the automobile as technologies that initiated transformative moments in modern history. It will take a while to appreciate this fully and adjust to the profound impact of the digital age. And it will take concerted effort. While it is common these days to marvel at the effects of technology on everyone's lives, the scale and scope of the changes may be even greater than they realize. In this essay, the author describes how MacArthur's approach to major programs in education and media is being recast. Then he discusses how technology is advancing existing strategies across the full spectrum of MacArthur's work worldwide, offering examples from its programs in the environment, population and reproductive health, and urban revitalization, among others.
