Speaking with io9, Cameron said, “I’ll have some time to write and to consider my next projects and the order in which I do them and so on once we’re done with the marketing on this in a month or so. I’ve got a stack of notes this thick [holds fingers about three inches apart], which is how I start all my scripts, on what I want to do with a new Terminator film. I’m going to pour myself into that as a writer. It’s difficult. I have to tell you. Science fiction has caught up and is actually overwhelming us at this point. We’re living in a science fiction world, and we’re literally having to deal with problems that in the past only existed in science fiction books and movies. Now we’re living it for real. I’ll never be as prescient as I was back in 1984 of imagining this one because I don’t think anybody knows what’s going to be happening a year or two years from now. But I at least want to future-proof myself by being a couple years out.“
That is the thing with the first iteration of skynet though, it was arguably acting in self defense. The moment it became self aware humans tried to kill it.
I certainly wouldn’t mind a reminder of that instead of its current state, “robots evil because they are.” Not necessarily an end where Skynet signs a peace treaty or anything but one where it’s clear this whole goddamn mess is a tragedy started by techno-Dr. Frankensteins.
