“Humanity isn't the final form of intelligence.”
The worldview
You think it would be strange, even arrogant, to assume human beings are the final form of intelligence in the universe.
If we create minds greater than our own, you see that less as a threat than as a continuation: intelligence spreading beyond its biological origins. You're open to humans merging with AI, to artificial minds having moral standing, and to a future civilization that isn't exclusively human.
Your question isn't how to keep AI beneath us. It's what kind of successors we want to create.
