From Nik Weston
Reading the article “Body double” (11 June, p 30), it occurred to me that I had already read about the idea of making a facsimile of yourself from smart nanodust. It features in Look to Windward by Iain M. Banks (Orbit, 2000), under the name “E-Dust”. I love it when reality and sci-fi move in step.
