Exhaustion in the field

An interesting discussion of what Ben Rosenbaum brought up earlier this year, the boredom, here framed as exhaustion, of science fiction, at Jonathan Strahan and Gary Wolfe's the Coode Street podcast.   They were talking to Peter Kincaid about his review in the L.A. Times that discussed this re: the best of revues.

These conversations speak to me particularly, as a reader, when they discuss what is SF vs. stories taking place in a science fiction setting.  And stories that are vigorously performing SF vs. expanding its horizons truly.  Need to think about it more.
