Consider the reality we're living in today. Schoolchildren kept in line by use of drugs such as Ritalin and Adderall. Technology that is as exasperating as it is necessary. Criminal syndicates operating at the speed of light from the other side of the world. A president with a record so convoluted and opaque that it's impossible to tell what is false and what isn't. (See Dick's short story, "The Mold of Yancy," in which a presidential candidate is totally unavailable and never seen outside of his video ads, because, it turns out, he doesn't actually exist.) Masses of people living in virtual alternate universes -- game clubs, social media -- in preference to dealing with the world as it exists. An encroaching surveillance state intent on tracking every living individual at all times under every possible circumstance. A would-be aristocracy slowly separating itself from the masses. Effectively invisible weapons that can kill from high altitude without the victim even knowing he was targeted.
What is this but a Philip K. Dick universe?
Dick, it seems, was a far superior prophet than the colleagues who disdained him, because, unlike many of them, he had a line on human nature, which never changes.
