I can't blame modern technology for my predilection for distraction, not after all the hours I've spent watching lost balloons disappear into the clouds. I did it before the Internet, and I'll do it after the apocalypse, assuming we still have helium and weak-gripped children.
In crime books it's possible to chart forensic technology by how well it has to be explained to a reader. In mid-Victorian crime novels fingerprinting has to be explained because it's new. Nowadays it's part of our world and we can simply assume that knowledge if we write about it.
The novel was set in an unspecified near future, because setting a novel in the present in a time of unprecedented technological and social dislocation seemed to me shortsighted.... To write a book set in the present, circa 2013, is to write about the distant past.
