Seems like a less advanced, but clearly more automatable version of the South Korean mother who was able to see her deceased 7-year-old in VR[0][1]. A friend of mine wrote a short story about this sort of thing a couple of years ago[2]. We actually spoke about it, and it got me to wondering what the business model of a service like this could be. Subscribing to receive videos from and communicate with a deceased relative. "Unsubscribing" would be like condemning them to the grave yourself. It's gross and scummy, but I could definitely see it being backed. Money on the table, I guess.
