The quantum revolution could turn many ideas of science fiction into science fact - from metamaterials with mind-boggling properties like invisibility through limitless quantum energy and room temperature superconductors to Arthur C Clarke's space elevator. Some scientists even forecast that in the latter half of the century everybody will have a personal fabricator that re-arranges molecules to produce everything from almost anything. Yet how will we ultimately use our mastery of matter? Like Samson, will we use our strength to bring down the temple? Or, like Solomon, will we have the wisdom to match our technology?
