I think financial prediction via machine learning will be a useful cruicible for defining AI from non-AI. So far, so many companies that have applied machine learning to prediction have ended up on the wrong side of the order book at the wrong time. I don't know if this is because other algorithms figure out what they are doing and rapidly develop a counter algorithm to fleece them, or if its just savvy traders intuition about what the algorithm is keying on and manipulating it. Sort of like good RTS game players that figure out how the opponent AI is playing and start playing against its programming rather than some strategy from first principles.
