But the problem is a real one, not a mere intellectual game. Because today we live in a society in which spurious realities are manufactured by the media, by governments, by big corporations, by religious groups, political groups. …So I ask, in my writing, What is real? Because unceasingly we are bombarded with pseudo-realities manufactured by very sophisticated people using very sophisticated electronic mechanisms. I do not distrust their motives; I distrust their power. They have a lot of it. And it is an astonishing power: that of creating whole universes, universes of the mind. I ought to know. I do the same thing. It is my job to create universes, as the basis of one novel after another. And I have to build them in such a way that they do not fall apart two days later.
How's that for prescience? Dick wrote that in 1978, for a speech titled, "How to Build a Universe That Doesn't Fall Apart in Two Weeks."
