> I feel like so much of Minority Report is prescient

That was a shallow movie if I ever remember one. How could a whole society idea of justice depend on just a set of 3 freaks detained in a kind of underground lab. This just does not make any sense, because it does not scale and it depends way too much on the human factor.

I'd wager that if such a thing ever exist in the future, it will be a matter of computers calculating probabilities based on a huge dataset they are constantly mining to detect abnormalities. But even if that were the case, it would probably fail to work unless you have a direct feed into everyone's private lives and way of thinking (and i don't mean just internet spying, it would need to go way further than that).
