It's my hunch that having immense data on all humans in one place, along with the potential to take programmatic action based on that data, may significantly increase the risk of massive, harmful affects on society on the decade to century scale. This may involve governments or other powerful entities co-opting the data, which there are increasing hints of. It doesn't even have to be some kind of catastrophy. One scenario I imagine would be something mundane like preventing an alternate future where the majority of people are twice as happy and have twice as much autonomy. Obviously, this can't be proven. But this hunch gives me great pause.
