A new research paper explores user interactions with "generative ghosts," AI systems trained on data from deceased individuals. The study, involving 16 participants, compared two design choices: "representation" (AI speaking in the third person about the deceased) and "reincarnation" (AI speaking as the deceased in the first person). Participants favored the "reincarnation" mode for its immediacy but expressed concerns about over-reliance, while "representation" was preferred for memory engagement, though users often engaged in dialogue regardless of framing. The research highlights that affective resonance was prioritized over factual accuracy, and that factors like tone and language shape these collaborative interactions. AI
