If one or two dozen human genes specific to brain development (out of the approximately 20,000 total in the human genome) can be spliced into other primates, then in a country where these would not in any way be legally considered human it might be possible to perform experiments on the resulting (legally) animal brains to allow creation of such a simulation. Of course we all know no country is performing such gene splicing, cough, cough.
