"Our homes are thousand-year-old concepts," Ahve says. "But we now have introduced heating, air conditioning, windows, security doors, electric lighting, elevator, television, water, sewage, and other developments," Reader says. "But electricity exists in only more-luxurious homes," Ahve says. "Let's formulate a concept closer to type-two civilizations. What is a house used for there?" "Eating, sleeping, storage, protection from the environment, and so on," Reader says. "We are optimizing life through available knowledge," Ahve says. "Let's consider sleep. Why do we need to sleep?"
