"But the beauty of movies is that they don't have to be logical. They just have to have plausibility. If there's a visceral, cinematic thing happening that the audience likes, they don't care if it goes against what's likely."
"I don't think anything resembling The Terminator is really going to happen. There certainly aren't going to be genocidal wars waged by machines a few generations from now. The stories function more on a symbolic level, and that's why people key into them. They're about us fighting our own tendency toward dehumanization. When a cop has no compassion, when a shrink has no empathy, they've become machines in human form. Technology is changing the whole fabric of social interaction. We're absorbing our machines in a symbiotic way, evolving to become one with our own devices, and that's going to continue indefinitely."
