No matter what exactly the mechanism is they use to end up with these hyper-specific results the end results is that by fusing data from an always expanding amount of sources companies are gaining insights into peoples lives which are nearing the almost mythical "all seeing eye" in a way that never happened before in human history. And I think we should ask really hard questions of whether society should continue to allow this or whether it should be reigned in. And we shouldn't accept vague "oh, you know, a person could do this too, so it's okay" or "companies are just persons" statements as an answer. Even for die-hard market fans there's the question if a market can work if the other side in an transaction knows everything about you.
