I hope that one day humanity will assess its gifts, its skills, and its history, and come to the conclusion that our purpose in this world is to cultivate and create life.
Certainly, this is what we have always done — not just in procreating, but in our efforts to domesticate animals, to breed new kinds of creatures, to grow plants and fruits and pets that would never survive in the wild. This has been with mixed results, but I think at the root of those impulses was the urge to bring more goodness into the world.
