"I am the last of my type existing today in all the Solar System. I, too, am the last existing who, in memory, sees the struggle for this System, and in memory I am still close to the Center of Rulers, for mine was the ruling type then. But I will pass soon, and with me will pass the last of my kind, a poor inefficient type, but yet the creators of those who are now, and will be, long after I pass forever. So I am setting down my record on the mentatype." What will the final evolution be, and will we recognize it when it arrives? A thought provoking story on the ultimate destination of all life.
