The document discusses the promise and implications of big data, and compares it to the uncanny valley phenomenon from robotics. While big data will transform many industries, using it for creative communications poses challenges. Inferring things about people based on their data can be disconcerting if not quite right. The uncanny valley offers insight into emotional reactions to big data, but creative communications aim to sell things, complicating its use. The document argues big data should be applied slowly, selflessly, and skeptically for creative communications.
