Tomasz Hollanek, a researcher at the University of Cambridge, says AI bots that are coded to mimic a deceased person could help preserve historical figures. But, if developed unethically, a late person's data could be manipulated to benefit a business model.

There's an emerging industry that uses artificial intelligence to create simulations of people who've died. These post mortem avatars are also called griefbots.
Some critics, including Tomasz Hollanek, a researcher at the University of Cambridge, say this practice raises a number of ethical issues. He walks us through the mechanics of how this technology works, and how it may or may not be used responsibly.
