You can now ask dead people questions, face to face. New software has been developed that lets people interact with a video of their deceased loved ones. What happens is that while the person is alive, they answer a list of questions that they think people might want to know. After they pass, loved ones can interact with the video by asking questions to the screen. The software recognizes the question and seamlessly pulls up the video answer for it. The man who developed the system put the first one together for his own mother who died.
I wouldn’t suggest letting young children ask the questions though. They’d just go into the never ending string of “why”s. It’d probably make the system explode.
