An industry is emerging that uses AI to build chatbots of people who’ve died. “Five years ago I would have said that most people would still find it kind of creepy. But then ChatGPT hit,” said Carl Orman, a Swedish researcher and author who has spent the past 10 years studying the ethics of the digital afterlife. “It’s not implausible that over the next decade or so, interacting with chatbots impersonating real humans becomes just as common as having a video call and that’s going to open up a new market for those chatbots.” The BBC’s Isabel Woodford looks at the business of grief-tech.
