They’re not real people 'cause they’re mostly CGI.
This is also true.
So really what I mean is the entire Robot vs Clone story is designed for one purpose: to allow massacres on a military scale to be sold to family audiences. It’s the last creative way possible to depict such a war. Some of it looks neat but that’s it. The same problem applies to most of the PT, since the concept artists are good at their jobs but can’t influence the real film making.
