"They hoover up so much info these days that it's pointless, because they don't have the ability to sort it or make heads or tails of it until they are directed to look at it specifically."

I've long considered this a saving grace. But this is one situation in which AI could trump humans with its sheer processing power, sorting through data and looking for patterns. And I don't like the implications of that.

Nowadays they only use it to direct pointed ads for girls' leotards or dance videos to your browser's sidebars, but there is potential for grave misuse of this technology, prying into people's private lives and exposing them to be judged by the court of public opinion (if not worse than that).
