And if A.I. can do all this kind of thinking, Hofstadter concludes, then it is developing consciousness. He has long argued that consciousness comes in degrees and that if there's thinking, there's consciousness. A bee has one level of consciousness, a dog a higher level, an infant a higher level, and an adult a higher level still. "We're approaching the stage when we're going to have a hard time saying that this machine is totally unconscious. We're going to have to grant it some degree of consciousness, some degree of aliveness," he says.
