From Harold Worby, Wheaton, Illinois, US
To answer the question “where is everybody?” we must consider the time period in which a technologically advanced civilisation maintains a broad coalition with the desire to put an immense amount of resources into interstellar travel. I can’t see anything in human history that indicates we are capable of that kind of long-term commitment. If the course of human development to date is a model of how other civilisations develop, then we will never meet any others.
