A dozen experts from four countries have collaborated with the Center for Responsible Nanotechnology, under the direction of IEET fellow Mike Treder, to create “a series of professional-quality models of a world in which exponential general-purpose molecular manufacturing has become a reality.  The purpose of this scenario creation activity is to offer plausible, logical, understandable “stories” about near-future worlds (circa 2020) in which we might actually live, and in which we must contend with the possibly severe military, political, economic, social, medical, environmental, and ethical implications of molecular manufacturing.  What will that future look like? What can we learn from picturing it now that might help us to avoid the worst pitfalls and generate the greatest benefits?  IEET Fellow Jamais Cascio conducted the workshop for CRN.  For more information about the scenario creation process contact Mike Treder.
