Further to my previous post, as you may also have heard, The New Yorker has published a science fiction issue, featuring fiction by Junot Diaz, Jennifer Egan and others, and non-fiction by Margaret Atwood, Ursula Le Guin, China Mieville, Colson Whitehead and others. The NY blog also has short interviews with the four fiction authors, plus some further discussion in a podcast.

Meanwhile, you can read in-genre reactions by Ryan Britt ("All of the short stories are written by awesome people [...] But none of them are actually science fiction or fantasy writers"), Sofia Samatar ("Individually, the pieces are very much worth reading, but when you put them all together, you get a pretty distorted picture of the genre"), Michael Ann Dobbs ("if all of these pieces are science-fiction, the editors at The New Yorker and Tin House have expanded the field more than anyone since the great pulp magazine editors"), and Maureen Kincaid Speller ("it perhaps wouldn’t hurt some genre readers to take a few steps beyond their own preconceptions about sf and take a look at this New Yorker").
