Charles Stross, one of the smartest cats on the planet, has put together a handy guidebook to singularity SF (and lots of other stuff besides) entitled Singularity! - A Tough Guide to the Rapture of the Nerds. Well worth checking out. Very tongue in cheek, very self-depricating, very funny. As I'm just at the bit in Paragaea where our heroes encounter a forest of talking trees (which none of the characters have the appropriate cultural context to recognize as Moravec-type bush robots) I thought this was particularly apt.
