New Matrix theory (If correct then its a spoiler)

[FS]

I like theorizing on the answers of the third movie as much as the next guy but there is such a thing as trying too hard. Of course using humans as batteries is not efficient. It does, however, make for a good sci-fi story. And yes, the idea of AI rebelling against humanity is rather flawed. That doesn't mean the creators must have thought of some backdoor to explain for that. It's fiction, not science.
