While still a student at MIT, a young Eric Drexler met O’Neill, for whom he worked as a research assistantat Princeton in the summer of 1974, funded by the wealthy patron and influential space colonisation spokeswoman, Barbara Marx Hubbard(another devotee of Teilhard’s ideas).408Drexler“went on to develop plans for lunar factories, solar sails, and methods to mine asteroids for mineral resources” and “was one of the L5 Society’s most articulate and vocal advocates for an expanded human presence in space.”409Butby the late 70s,Drexler began to turn his attentionto a new concept, nanotechnology, which fed into the space colonisation dream, but also broadened the emphasis of the L5 space-age, human potential movement, into something that underpinned cryonics and life-extensionist ambitions,and other facets of what later became a distinctly transhumanist vision of the future.
