Eric Drexler introduced the world to nanotechnology in his first book, Engines of Creation: The Coming Era of Nanotechnology. In his newest book, Radical Abundance, Drexler presents a range of information, informing the reader of the process of nanoscale manufacturing, current efforts and research (and hurdles), and the benefits to science, society, and the planet once we achieve the reality of nanoscale fabrication.
Drexler presents APM (atomically-precise manufacturing) as the next revolution, the first three being agriculture, industrial, and information. This revolution will be powered once we control "the molecular machinery of life (using) proteins that can fit together to form motors, sensors, structural frameworks, and catalytic devices..." By using natural systems to construct from the atomic level towards larger and more complex products, we can manufacture efficiently, using common chemical substances in place of minerals and metals acquired through ecologically damaging mining, and to create materials we cannot visualize today.
In Drexler's future, APM solves many of the societal issues that create poverty, ecological disasters, and conflict. It's an important work that gives us a future to look forward to when so many visions are broken and dystopian.
