realistic depiction, such as computer-generated animation, that is difficult to distinguish from the recording of a real person.
The interpretation being used here seems to be that any hyperrealistic CGI animation is illegal. But that's taking a broad interpretation of "a real person". In The Dark Star Republic, we interpret that part more literally: it really has to be indistinguishable from a specific real person who exists to be considered illegal. Merely being very humanlike, but not actually resembling any specific real individual, isn't something we consider illegal.
Thus, creating a CGI animation of your 15 year old neighbour, would be illegal; creating a realistic CGI of a generic 15 year old, not using any recognisable character features from an actual person, would not be.
This is the interpretation we think makes most sense given the proposal is concerned with child welfare, not pixel welfare.
