These are the time displacement machines, which store the arrogant society, which is needed by Skynet to arrive here, iteratively, but it lost to John Shah. Causing John Shah, to bring Skynet here to the world, in which the entire human resistance team was eradicated. So you see, it is a vicious cycle of evil, why ?, because evil stays arrogant, and stays covered up. Nothing more to add I have to this chapter of bringing Skynet down, that it will be back ! Isolation is the only game now, that can keep the mishap here, at bay, by never playing it again, Rt will be broadcasted here ubiquitously. No mishap, just a normal house, or facility, even a station, that keeps running with power and communications up. The mishap is only a news on TV here, nothing real.
