I don't think this is anything revolutionary at this point. We already have a precedent with something similar in Hatsune Miku. Miku a computer generated vocaloid, and isn't a real person. There is a person behind the voice, software, and visuals. But giving it AI to add personality and mimic the original is a good concept. I can see Taylor Swift fans using it. It will be popular with anime fans that want to make their favorite anime characters "come to life" and interact with them. This can bring us closer to the AI and robot partners in Bladerunner.
