EDIT: Tell us what characters you want to see in the comments and we can make them for you to talk to (e.g. Max Headroom)
Sure, that kind of thing is great fun. But photorealistic avatars are gonna be abused to hell and back and everyone knows it. I would rather talk to a robot that looks like a robot, ie C-3PO. I would even chat with scary skeleton terminator. I do not want to talk with convincingly-human-appearing terminator. Constantly checking whether any given human appearing on a screen is real or not is a huge energy drain on my primate brain. I already find it tedious with textual data, doing it on realtime video imagery consumers considerably more energy.
Very impressive tech, well done on your engineering achievement and all, but this is a Bad Thing.
