Generative models can be fed data of a deceased person, which some companies have dubbed "grief bots." Jack Manning recently published a study of people interacting with their past loved ones this way. The results were positive.

There's a growing market for AI models that promise to recreate the experience of interacting with a lost loved one. They're sometimes called generative ghosts, and they're the topic for today's “Uncanny AI,” our series about sometimes-unsettling experiences with this technology.
Jack Manning, a Ph.D. candidate studying information science at the University of Colorado Boulder, has been looking into this. He recently published a study on how people experience talking to generative ghosts.
