One thing that I think AI does far better than humans is to make accurate long term predictions. Humans are pretty terrible at that. I'm not coninved we will ever see a Skynet/Terminator scenario like some people fear, but I think we could reach a point where the data AI is producing is far to complicated for humans to understand anymore. AI may not have intellegene or consciousness like humans, but if it reaches a level of complexity that is beyond our comperhension I'm not sure it will matter.
