A computer engineer from Silicon Valley employs a powerful thought experiment to explore the economy of the future. An imaginary "tunnel of lights" is used to visualize the economic implications of the new technologies that are likely to appear in the coming years and decades. Challenged are nearly all conventional views of the future and the danger that lies ahead if we do not plan for the impact of rapidly advancing technology is illuminated. It also offers unique insights into how technology will intertwine with globalization to shape the remainder of the 21st century, and explores ways in which the economic realities of the future might offer new approaches to addressing global challenges such as poverty and climate change.
