These videos will and may be too realistic.
Our society is not prepared for this kind of reality "bending" media. These hyperrealistic videos will be the reason for hate and murder. Evil actors will use it to influence elections on a global scale. Create cults around virtual characters. Deny the rules of physics and human reason. And yet, there is no way for a person to detect instantly that he is watching a generated video. Maybe now, but in 1 year, it will be indistinguishable from a real recorded video
