The motives and goals of a super-intelligent post-Singularity creature might be unknowable to us—but so, presumably, would the motives and goals of any “traditional” KIII civilizations that might exist. Yet we are happy to think about how to detect such KIII civilizations. In fact, we might have more chance of understanding the post-Singularity beings on Earth than we would of understanding extraterrestrials, because in some sense those entities would be us.
