I shall not assess arguments and evidence for competing views about when human extinction will occur. We know it will occur, and this fact has a curious effect on my argument. In a strange way it makes my argument an optimistic one. Although things are now not the way they should be—there are people when there should be none—things will someday be the way they should be—there will be no people. In other words, although things are now bad, they will be better, even if they first get worse with the creation of new people. Some may wish to be spared this kind of optimism, but some optimists may take a measure of comfort in this observation.
