My theory remains the same, and intact. The entire Terminator franchise is fiction, therefore no plot holes exist. Fiction does not have to follow the same rules as reality. Anything anyone calls a plot hole in fiction is actually either "something that was inadequately explained by the writer," "something intentionally left as a dangling thread by the writer," or "a wizard did it." Those 3 explanations are sufficient to explain any so-called "plot hole" I've ever encountered. I mean if you need to "explain" how the terminator franchise fits together, it's continuity, then... uhh, parallel realities. Each movie exists in it's own parallel universe and doesn't impact any of the others at all. And in the movies that seem to contradict their own internal consistency... the film had to follow several different possible realities to show all the scenes the author wanted to while at the same time choosing realities that keep the main characters alive and lead to the ending the author or authors wanted. BAM, done, it all fits. It only exists in the first place because the writers chose to create it in the first place. That's why things happen the way they do, because the writers SAY they happened that way. Because the story exists in a reality where that's just how things work.
That's why I say there's no such thing as a "plot hole" in fiction. But in order not to be too much of a killjoy, working out how things in a franchise or movie or series of books or whatever... is part of the fun. But in something like Terminator (where so many things are left to the imagination) I personally have to find enjoyment in something other than trying to understand the physics and cosmology of a reality that doesn't exist. Like watching robots firing lasers, blowing up trucks, powersliding vehicles... typical action movie stuff. Which, in my opinion, the Terminator franchise delivers better on than it does explaining it's own internal logic. Which was a very roundabout way of agreeing with the OP, trying to work out how the terminator universe "works" is like beating your head against a wall.
