Artificial intelligence already allows deceased relatives to be “revived” and opens an ethical debate

When he wanted to give a gift to his father, who sacrificed a lot to raise him as a single parent, Lee Geon Hui came up with an unusual idea: an animated video message using artificial intelligence of his late grandfather, who is greatly missed by his father.

Lee wrote a message and, in December, hired Seoul-based technology company Vaice, South Koreato create a short video featuring a digital replica of his grandfather reading it. The virtual character referred to his father as “my dearest son” and apologized for forcing him to help with farm work when he was a child and for having opposed his son’s decision to become a hairdresser.

“My father said he wasn’t going to watch the video. But in the end he watched it and he cried. So I felt rewarded,” Lee, a 28-year-old office worker, said in a recent interview. “I wrote the script… because it was what I really wanted to say to my father.”
