The problem is that it's already done. All our info has been collected for at least the past 15 years.
Who gives a shit about that? Honestly what I'm curious about is if the shadier tech people have been using the information to network with other shady people. The problem is trying to give a group of trusted people the access to that wealth of information. Face it, assholes like Zuck already know if you like cake farts and midget porn.
