One night in the fall of 2020, a freelance writer named Joshua Barbeau typed a sentence into a chatbot and his fiancée answered. She had been dead for eight years [1].
He had fed a language model her old texts and a short description, using a service called Project December. The conversations that followed, reported at length by the San Francisco Chronicle, read the way ghost stories have for centuries: intimate, uncanny, comforting, wrong, right. He knew it wasn’t her. He kept typing anyway.
Five years later, that experiment is an industry. This is the tour: who’s selling what, what psychology says, what researchers are warning, and the one thing you should decide on purpose, in writing, while you’re alive.
