We're all in favor of world-domination by robots, particularly benevolent, Japanese robots. Get a glimpse of the future at Robotopia Rising beginning today at the Kennedy Center in Washington, D. C. Eleven days of robots and robot-related souvenirs await you. There will also be "robot lectures," which may be lectures by robots or about robots. We aren't sure. But this is our favorite: a robot "with artificial lips that move with the same finesse as human ones, enabling it to play the trumpet."
