Arguments are presented which show that motives for interstellar travel by advanced technological civilizations based on an extrapolation of Earth's history may be quite invalid. In addition, it is proposed that interstellar travel is so enormously expensive and perhaps so hazardous, that advanced civilizations do not engage in such practices because of the ease of information transfer via interstellar communication.
