AI ghosts are coming: Is that comforting or creepy?

In 2019, a grieving mother named Jang Ji-Sun donned a virtual reality headset and was instantly transported to a grassy field where she spent 10 minutes playing with an AI version of her daughter, Na Yeon, who had died three years earlier of a rare blood disease.
The tearful reunion, viewed more than 36 million times on YouTube, offered a striking sneak peek at how technology might someday transform the way we interact with the dead.
Thanks to the advent of generative AI technologies like ChatGPT, and the emergence of AI 鈥渁gents鈥 created to act independently on behalf of their creators, that someday is here, according to new 色戒成人直播 research. And the possibilities are even wilder than many imagined.
鈥淲e anticipate that within our lifetimes it may become common practice for people to create custom AI agents to interact with loved ones and the broader world after their death,鈥 writes Jed Brubaker, professor of Information Science, in a new paper titled 听鈥.鈥

Information Science Professor Jed Brubaker
Brubaker has spent much of his career at the intersection of death and technology. His research inspired Facebook鈥檚 Legacy Contact, the feature which enables platform users to assign someone to manage their account after they die. In November, he launched the nation鈥檚 first Digital Legacy Clinic, which helps people get their digital affairs in order.
For his latest paper, co-authored with Google DeepMind researcher Meredith Ringel Morris, he set out to inventory what鈥檚 been done and what鈥檚 coming in the nascent 鈥淎I afterlives鈥 space. Meanwhile, in his lab on campus, Brubaker and his students have begun beta testing their own "AI ghosts" and conducting experiments to test how people feel about them.
鈥淭oday, you might interact with a Facebook memorial page for grandpa after he dies,鈥 he says. 鈥淏ut what would it feel like to actually sit down with grandpa by the fire and have a conversation with him?鈥
That day may not be far off.
From text-based grief bots to resurrected celebrities
As Brubaker notes, tech-savvy futurists have been dabbling with AI afterlives for years.
After Velvet Underground frontman Lou Reed died in 2013, his partner Laurie Anderson worked with machine learning experts to create a text-based chatbot (trained with Reed鈥檚 writings, songs and interviews) that she could converse with. She still uses it frequently.
鈥淚 am totally, 100% addicted to this,鈥 Anderson recently told The Guardian.
In 2023, surviving members of The Beatles used AI to release a new song 鈥淣ow and Then鈥 featuring the deceased John Lennon鈥檚 voice singing along with his bandmates.
Just last month, the family of a man shot dead in a road rage incident used AI to create a life-like avatar of him. During an emotional video played in the courtroom, the avatar forgave his killer.
Meanwhile, numerous startups now help the living create posthumous digital versions of themselves: After a lengthy 3D video and interview session, Re;memory will create a 鈥渉ighly realistic AI avatar鈥 to leave behind for family members. HereAfter, an AI app, invites people to record audio stories that the 鈥渧irtual you鈥 can share after your death.
To some, this all sounds exceedingly creepy.

But Brubaker points out that photographs were once believed to steal a person鈥檚 soul, and online memorials鈥攚idely viewed as creepy a decade ago鈥攁re now everywhere.
鈥淎fter time, what鈥檚 creepy often becomes commonplace,鈥 he says.
The rise of generative ghosts
Brubaker is most intrigued about what鈥檚 coming next: He and his co-author term them 鈥済enerative ghosts.鈥
Powered by large language models that can generate and understand human language, and other features that enable them to remember, plan and exhibit other complex human behaviors, they can do far more than regurgitate old stories fed to them by the once-living.
For instance, they could have a conversation with their kids about current events which occurred after their death, write a new song or poem (that their family could potentially earn royalties from), or even help their kids manage their estate.
Right now, most generative ghosts are rudimentary and text based. But ultimately, we could get very close to that candid chat with grandpa by the fire, Brubaker says.
鈥淵ou could go interact with this super high-fidelity, interactive memorial and, instead of them just reading you some pre-scripted words, you could have an authentic conversation.鈥
Promise and peril
Brubaker also imagines a day when generative ghosts could be used therapeutically for someone struggling with prolonged grief over a lost loved one.
This was, in fact, the impetus for Jang Ji-Sung鈥檚 . (After three years of battling mental health issues, she worked with a South Korean TV network to create a 3D version of Nayeon she could bid a final farewell to.)听

Generative ghosts could also be used in historical exhibits.
鈥淭he last generation of Holocaust survivors will not be with us for much longer, so museums are trying to think of rich, interactive ways to keep their stories alive,鈥 says Brubaker.
Along with such promise, of course, comes peril.
How long should someone interact with an AI ghost before it becomes unhealthy? What role should they play, or not, in the courtroom? What happens when they are created accidentally (e.g., someone creates an AI 鈥渁gent鈥 to perform other tasks for them and then unexpectedly dies)? How can I be sure no one will make a ghost out of me, against my will?
And when and how should a generative ghost die?
Brubaker doesn鈥檛 have the answers. But he hopes his research will get tech companies and policymakers thinking.
鈥淲hat鈥檚 possible and what will actually happen are two different things as we move forward in this AI world,鈥 he says. 鈥淲hen it comes to AI afterlives, we hope to see things move forward in the most ethical, thoughtful and sensitive way possible.鈥
