I read somewhere, maybe even Wikipedia, that the reason Bud dies so early in the The Diamond Age is that his character represents a stereotypical cyber-punk character and Stephenson is signaling that cyber-punk is over - this work of fiction is going beyond that. Stephenson then does a 90 degree turn genre-wise and does a historical fiction with Cryptonomicon. And he deepens that with The Baroque Cycle. Recently I read Anathem, a more typical science fiction novel in that it ostensibly involves aliens instead of a future Earth. Yet the steady stream that unites all of these books as Stephenson titles is the constant exploration of technology and its effects on society. It doesn’t matter whether that takes place in the future, during World War 2, or on another planet.
