"We all have weak moments, moments where we lose faith, but it's our flaws, our weaknesses that make us human. Science now performs miracles like the gods of old, creating life from blood cells or bacteria, or a spark of metal. But they're perfect creatures and in that way they couldn't be less human. There are things machines will never do, they cannot possess faith, they cannot commune with God. They cannot appreciate beauty, they cannot create art. If they ever learn these things, they won't have to destroy us, they'll be us."
