Starborne

In Starborne, Silverberg takes the Utopia theme and turns it on its head. The scene is Earth many centuries in the future, where all of life's problems have been solved. But while humanity may be well fed, amply clothed, in perfect health, and rich beyond imagination, people are bored nearly to death. To bring a little spark back into the lives of humankind, the people of Earth band together to build a starship and begin the search for habitable planets in the rest of the universe.
