Safeguarded from harm and malevolence, it serves only one purpose: to simplify human life. Join Agent Black on a journey as it tackles what seems like a straightforward user request: finding the perfect birthday celebration spot. Will it succeed? Will it satisfy the user? It’s more challenging than one might think. Agent Black must travel deep into the parallel world of virtual networks to uncover the right answer. This academic graphic novel humanizes key elements of a decentralized human-centered AI system, recounting Agent Black's quest to fulfill its purpose. By attributing human characteristics to agents representing their owners in the digital world, allowing them to feel joy and despair, and using humorous analogies of a world of individuals going about their daily lives, the story demystifies complex AI concepts and makes the formal logic-driven domain accessible to a wider audience. It also interweaves expert discussions on specialized scientific topics related to the human-centered AI journey, providing in-depth insights in an approachable manner.
