“The presence/absence of mobile phones in one’s fictional worlds is going to be, I suspect, no trivial matter. Because so much of the mechanics of novel writing, past and present, is taken up with making information available to characters or keeping it from them, with getting people together in the same room or holding them apart. If, all of a sudden, everyone has access to more or less everyone else – electronic access, that is – what becomes of all that plotting?”
