Before K. Eric Drexler devised and proselytised for his particular, visionary, version of nanotechnology, he was an enthusiast for space colonisation, closely associated with another, older, visionary for a that hypothetical technology – the Princeton physicist Gerard O’Neill. A recent book by historian Patrick McCray – The Visioneers: How a Group of Elite Scientists Pursued Space Colonies, Nanotechnologies, and a Limitless Future – follows this story, setting its origins in the context of its times, and argues that O’Neill and Drexler are archetypes of a distinctive type of actor at the interface between science and public policy – the “Visioneers” of the title. McCray’s visioneers are scientifically credentialed and frame their arguments in technical terms, but they stand at some distance from the science and engineering mainstream, and attract widespread, enthusiastic – and sometimes adulatory – support from broader mass movements, which sometimes take their ideas in directions that the visioneers themselves may not always endorse or welcome.
It’s an attractive and sympathetic book, with many insights about the driving forces which led people to construct these optimistic visions of the future. (more…)
