There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them. In fact, the avatars are the newest manifestation of a cultural tradition: Chinese people have always taken solace from confiding in the dead. The technology isn't perfect--avatars can still be stiff and robotic--but it's maturing, and more tools are becoming available through more companies. In turn, the price of "resurrecting" someone--also called creating "digital immortality" in the Chinese industry--has dropped significantly.
