- K. Eric Drexler
The ideas in this book have been shaped by many minds. All authors bear an incalculable debt to earlier writers and thinkers, and the Notes and References section provides a partial acknowledgment of my debt. But other people have had a more immediate influence by reading and criticizing all or part of the several papers, articles, and draft manuscripts ancestral to the present version of this book. Their contributions have ranged from brief letters to extensive, detailed criticisms, suggestions, and revisions; they deserve much of the credit for the evolution of the manuscript toward its present form and content. I do, however, claim all blame for its remaining failings.
