Technology that lets us "speak" to our dead relatives has arrived. Are we ready?

I asked Dad, since he was clearly in such a candid mood. "My worst quality is that I am a perfectionist. I can't stand messiness and untidiness, and that always presents a challenge, especially with being married to Jane." Then he laughed--and for a moment I forgot I wasn't really speaking to my parents at all, but to their digital replicas. This Mum and Dad live inside an app on my phone, as voice assistants constructed by the California-based company HereAfter AI and powered by more than four hours of conversations they each had with an interviewer about their lives and memories. The company's goal is to let the living communicate with the dead.
