Re: Perhaps in theory.
At the end of all that processing, there's an increasingly decent chance the woefully inaccurately targeted ad will only end up being stripped out by an adblocker in any case; Google trends shows a steady rise for searches for adblock over the past few years, and I can't see adblock installations falling anytime soon. More poorly targeted ads trying even harder to chase fewer eyeballs will only push more into installing something to get rid of them.
Beyond the use of the data for advertising though, there doesn't seem to be anything else that would generate the large profits everyone's chasing now. With rising objection to the way data is collected and used as the process is more widely understood, I can see the whole gravy train being brought to a shuddering halt in the not too distant future.
