“I think the world will always need Star Trek as an example of what a better world will be and what we can do as individuals to further the dream. I think there are very few humans who believe we are alone in the universe and we hope the First Contact will lead to that dream. I think the talents of the writers of science fiction from Isaac Assimov to Harlon Ellison, Ray Bradberry combined with the vision of Gene Rodenberry have opened our minds and hearts to individual responsibilty, cultural morality and technical achievements.”
