Dinosaurs are extinct, kaput, dead.
They're in the evolutionary Old-Timers' game. None are alive, not even one little tiny one. Dead, dead, dead, dead. No, what killed the dinosaurs was that they all sat around watching movies about humans, or PBS specials about humans, or museum shows featuring robotic humans, and they got fat and lazy and the mammals sneaked up and snatched the evolutionary limelight. We're heading for the same fate.
