1 . I spoke to my parents last night and for a moment I forgot I wasn’t really speaking to them, but to their digital replicas (复制品). They live inside an app as voice assistants constructed by the company HereAfter AI.

In fact, my parents are still alive and well; their virtual versions were made to help me understand the technology. Grief tech, which lets you “talk” with the people you’ve loved and lost, has been appearing in science fiction. But now it’s becoming a reality. Although the thought of it makes some frightened, it’s not hard to see the appeal that people might turn to digital replicas for comfort.

However, there is one major limitation. These replicas may sound like someone you love, but they know nothing about you. Anyone can talk to them, and get the same reply in the same tone. “The biggest issue with the technology is the idea that you can generate a single universal person,” says Justin Harrison, founder of a technological service.

Creating a virtual avatar you can have more conversation with contributes to your feeling connected to someone you loved and lost, says Erin Thompson, a clinical psychologist. But a grieving person needs to know that these bots can only capture a small part of someone rather than replace healthy, functional human relationships.

And there are other risks. Any service that allows you to create a digital replica of someone without that person’s participation raises complex moral issues. While some might argue that permission is less important with someone who is dead, can’t you also argue that the person who generated the other side of the conversation should have a say too? And what if that person is not, in fact, dead?

If digital replicas become mainstream, there will inevitably need to be new regulations around what we leave behind online. And we’ll be better off if we cope with the possibility of these replicas’ misuse before, not after, they reach mass adoption.

Anyway, I feel lucky to still have the precious opportunity to spend more time with my parents, face to face, no technology involved.
