Hollywood mogul James Cameron says he would not like to change anything about his life. "I don't think it's a good idea to change anything. If I were unhappy in my life, you might get a different answer," Cameron said when asked what would he change about his past. "But I don't think we know enough about causality to be able to make a change because you could get a butterfly effect from the most innocent of changes -- the most obvious being to go and whack Hitler before he took over. But that wouldn't change human nature and leaders like that will always emerge. There are certain inevitabilities," he added.

Connecting the concept of time travel with his upcoming "Terminator: Dark Fate", the producer said: "And one of the themes of the movie, to bring it back around, is that the emergence of an artificial super-intelligence is inevitable. It's what we call the 'kick the can effect', you know? Sarah Connor kicked the can down the road, by preventing 'Judgment Day' in 1997, but she didn't prevent it from ever happening. It's going to constantly come back. It's like in Chaos Theory what you'd call strange attractors, it's always going to happen, probabilistically."
