Famous quotes containing the words missing and/or data:
“Kids and violent TV, violent TV and violence, violence and kids. The only people missing from this discussion are the parents. Where are we? Gone. Abdicated.”

“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
