The Visioneers: In Pursuit of Space Colonies, Nanotechnologies, and a Limitless Future


Friday, November 8, 2013 - 11:30am to 1:00pm


Event Details

Some rare individuals possess a clear vision of an expansive future created by technologies they study, design and promote. This talk explores the activities of “visioneers” Gerard O’Neill and Eric Drexler who advocated space settlements and nanotechnologies in response to perceived threats of eco-catastrophism and planetary limits.

Visioneers and the communities of researchers, futurists and entrepreneurs they attracted have often existed at the blurry border between scientific fact, technological possibility and optimistic speculation. Considering visioneers as a particular analytical category provides an opportunity to reexamine the uptake and adoption of radical ideas in contemporary technological ecosystems.
