As Moore's Law and AI advance inexorably, more and more less specialist individuals are going to apply more outside the box mechanisms to use big data. Hacker News discusses the recent release of a facial recognition method for comparing social media pics with porn whose maker has claimed over 100k identifications to date. For some reason there's a lot of upset over this, with some even calling it dystopian. I think rather the reverse myself.
I have for some time responded to plaints about the loss of privacy with this very prophecy: by using facial recognition technology and individually owned surveillance data stored on publicly auditable blockchains free people can establish far greater control of society, government, and their own property. Covert ops and crime are going to be more and more difficult to get away with, and not just secret porn careers funding college educations.
Have a look at the state of decentralized big data today, and consider the better future to come as a result.
