My response to almost all terminator doomsday hubbub is always as follows.
"Think about how often cars breaks down, think about how often you have to repair your computer, how often it just breaks for no reason. Think about how simple it is to break a program by removing a single character. Think about how fragile our tech is and likely will be for the next hundreds of years. Terminators would probably make it halfway out the door and then proceed to keel over."

Isaac Asimov called it the Frankenstein Complex. It's because of stories like Frankenstein that a lot of western cultures have a fear of robots. Japan, on the other hand, frequently depicts robots as heroes. It's kind of the opposite of views towards nuclear power (in the US, it gives you superpowers; in Japan, it creates kaiju).
