So far, the gathering of great deals of data on people has not been used for purposes that benefit such people. For example, one of the biggest uses of mass surveillance and data collection is to improve the targeting of marketing, which generally does not benefit the people being marketed to, and indeed often is done to their detriment.

And then a side effect of all of this is that this huge mass of data is just sitting there to be used for even more nefarious purposes. I can easily imagine a world where an end user is required to submit their genetic data in order to prove their age for an age-controlled app, for example.
