Marina Smith, a 87-year-old woman who passed away in June, was able to address the mourners at her own funeral in the UK — sort of, at least, thanks to the power of artificial intelligence.

The woman was able to surprise the guests at the funeral in the form of a “holographic conversational video experience,” created by a startup called StoryFile.

The company was founded by Smith’s LA-based son Stephen and was originally created to preserve the memories of Holocaust survivors.
