How would a conqueror AI eliminate us? Probably by a method that we wouldn't even understand, at least not until it was too late. Imagine a group of elephants 100,000 years ago discussing whether those recently evolved humans might one day use their intelligence to kill their entire species. "We don't threaten humans, so why would they kill us?" they might wonder. Would they ever guess that we would smuggle tusks across Earth and carve them into status symbols for sale, even though functionally superior plastic materials are much cheaper?
