I've seen discussion of "cutting-edge" science fiction and what it means, quite a bit. Generally, there are two camps:

One argues that the absolute edge of science fiction is sci-fi that is rooted in the latest scientific knowledge and theory, and in likely further developments on current bleeding-edge technology.

The other argues that science fiction's "cutting edge" is fiction that explores the anxieties and fears of today, pushes the boundaries of how we think about fiction and about our lives, and generally tries to show the world in new ways.

Without choosing one over the other as the "right" answer, since I think both are legitimate things to look for in science fiction, I'm more interested in the fact that, while fantasy obviously has little to do with the first definition, it can, in theory, fit the latter. So, using this second definition of "cutting edge," what would you consider today's cutting edge fantasy, that explores the boundaries of what fantasy as a genre can do, deals with social, philosophical, and psychological matters in an interesting way, and generally is likely to blow the minds of its readers?
