If copying everything wholesale is possible before brain science is able to fully understand every detail brain scientists want to write a thesis about, then using systematically modified copies for "knock-out" studies will seem like a very tempting methodology. Also gives researchers numerous virtual insane patients to try virtual drugs on. Or perhaps something with some clear virtuous intent (and nothing particularly tortuous)... what about running Monte Carlo simulations using many identical instances of the same copy to find which pedagogical method(s) and steps best educates someone about a difficult to grasp subject? Even when the creation of the virtual minds is only of good intent, one can wonder about the ethics of it. What if anything is owed the legion of virtual students after the classes are done? I suppose some of them could be given some other useful employment to earn their watts.
