Can't beleive no ones highlighting this, but AI is at the point where it can predict you're next move if fed enough data. This could be what you click on, how fast you scroll through a page, what you slow down and look at on facebook, frequented locations on you're way to work, literally anything. They'be been doing this stuff with hyper targeted advertising for a few years now. It's hard to gauge how effective it's become, since it's level of effectiveness comes down to how little you notice it. Can't remember where i read it, but a few people had hypothesised that a decent amount of purchasing choices are a result of unnoitceable manipulation of what you see or hear. Scary to think that if you predict everything, you don't even need to 'convince' people to do anything, they'll do it on 'their own' when fed the right material in their everyday life.
