Think about what life in a space colony would be like: a hermetically sealed, climate-controlled little nothing of a place. Refrigerated air, synthetic materials, and no exit. It would be like living in an airport. An airport in Antarctica. Forever. When I hear someone talking about space colonies, I think, that’s a person who has never studied the humanities. That’s a person who has never stopped to think about what it feels like to go through an average day—what life is about, what makes it worth living, what makes it endurable. A person blessed with a technological imagination and the absence of any other kind.
“All in a Dream," William Deresiewicz (The American Scholar)
