I keep going back to those old cities, where billions of people used to live, trying to figure out what they used to do, how they conspired and got those machines here. But they are not that developed yet, just T 800s, they keep changing things here, their is residue of the time machine being used here, several times. A chicken and egg rule does not apply here anymore, their is no time line left anymore, instead of time, we use some knm, that’s like using some other dimension. They use time, we use k.
