Exactly. You're description is drastically more complex therefore is drastically less likely to be correct.
I'm being a "bump on a log" here because science fiction (light on science & very heavy on fiction) is fine for amusement. However as computer scientist it's quite important to grasp the scale of thing before attempting a find a solution.
So you think generate data for AI is more complex than universe? Did i missed something? You even no need to generate random events. AI can think he is decide by himself, but "we all know" this is only simulation.
