The latest New Scientist magazine has soundbites from writers like Gibson and Atwood and much else. Give it a read.
E M Forster in Aspects of The Novel, asks a pertinent question: Will the mirror get a new coat of quicksilver? Will the creative process itself alter? (By mirror he means novels, and the creative process is story telling – through words, paint, clay…).
This is the kind of meta question about art that only those who engage in speculative fiction can address, IMO. Science, of course, is the best possible vehicle for speculation because it is more consistent than most other quicksilver coatings.
