I am thinking of highly dimensional and complex systems subject to significant noise, and operating over many time scales e.g. real-world economics and financial systems. Also, I’m talking about real-world, practical AI, which can be implemented to generate whatever output over a practical time-frame (as opposed to a theoretical AI given infinite data and time). I have no evidence to back this up, just my educated guess.
