There's a short story by Kafka, "Investigations of a dog," that seems to ask the same question from the perspective of a dog. This dog notices that there are phenomena that it can't explain, such as why dogs dance around and make certain noises, just before their food appears. On the one hand, it can't manage to get its fellow dogs interested in these questions. On the other, it catches glimpses of a higher species of dogs who are invisible but somehow bring its food. I'm thinking in a similar vein, of what behaviors are inexplicable in humans, such as why we hold hands and recite certain verses before we receive our food, or are so mesmerized by particular sequences of tones and sounds that some other humans seem compelled to make. Some possible clues: - Hearing new kinds of music that is noticeably not meant for human listeners, e.g., if it is not based on an analysis of human music. I'm only imagining that a real intelligence will eventually get sick of our music and come up with something that it prefers. If it cares about music, of course. - A sustainable improvement in the management of humans, resulting in more uniform and better health. This is an analogy to the fact that our livestock live under more uniform conditions than wild animals. Assuming that humans are useful for AI, or that they're even aware of our existence. - A use for the blockchain. ;-)
