“Different civilizations grow old and die in different ways, just like different people die of different diseases or just plain old age. For the God Civilization, the first sign of her senescence was the extreme lengthening of each individual member’s life span. By then, each individual in the God Civilization could expect a life as long as four thousand Earth years. By age two thousand, their thoughts had completely ossified, losing all creativity. Because individuals like these held the reins of power, new life had a hard time emerging and growing. That was when our civilization became old.”
