I always seem to take an opinion that there is a more sinister agenda afoot with this kind of news. Especially with big brother loving corps like FB..
I think they would like to link medical records, social habits and skills, and also, as we see more and more ads for, getting everyone's entire genome mapped and archived. All working in conjunction to completely map someone's "self".
No more freedom at that point. Genetic predispositions and the likes.. all able to be predicted. So they can weed out the weak..
Radical theory sure.. but seemingly more and more of a reality.
