IMHO, we are at the age where human existence in the virtual world is one of the consciousness. As Jean Baudrillard said, we are now at the age of Hyperreality. I believe vtuber is a part of consciousness of a human behind. Although at this stage, it is part of a role play, a kayfabe by someone. As mentioned by Zimbardo in Lucifer Effect, roleplaying when done repeatedly becomes part of that person. The roleplaying affects the real world. The persona played by the person behind becomes the part of the person itself. That's why the character becomes someone. There is an "id, ego, and superego" that becomes the character's engine. How can AI replace that engine? This part needs to be tackled by AI first. The AI needs to be able to "hallucinate", or generate random factoids, with a consistent manner. Being someone like that, it needs to be fed with the right input. Human beings the super group of sensors is constantly build its knowledge by the input from those...
