alt Hacker NewsIf you consider a person, their brain in particular, flowing backwards in time, the brain becomes a prediction tool. Events-memories (neural connections) appear out of nowhere (from the state of being 'forgotten' in the forward time flow) then completely disappear when the corresponding event happens, annihilating its 'predicting' memory.
The brain does want to predict (in fact I think that's what it's suppose to do), the problem is that the Earth is rather chaotic and unpredictable.
If you subject a brain-like neural network to watch planets and stars orbiting around each other and rewarding it for getting things right, it will likely do quite well.
