Some more predictions from Norman Mailer’s 1970 Space Age reportage, Of a Fire on the Moon, which have come to fruition even without the aid of moon crystals:

“Thus the perspective of space factories returning the new imperialists of space a profit was now near to the reach of technology. Forget about diamonds! The value of crystals grown in space was incalculable: gravity would not be pulling on the crystal structure as it grew, so the molecule would line up in lattices free of  shift or sheer. Such a perfect latticework would serve to carry messages for a perfect computer. Computers the size of a package of cigarettes would then be able to do the work of present computers the size of a trunk. So the mind could race ahead to see computers programming go-to-school routes in the nose of every kiddie car–the paranoid mind could see crystal transmitters sewn into the rump of ever juvenile delinquent–doubtless, everybody would be easier to monitor. Big Brother could get superseded by Moon Brother–the major monitor of them all might yet be sunk in a shaft on the back face of the lunar sphere.”
