Completely wrong on the political side (maybe because I'm not US-based), but otherwise not bad at all:

- astonishing geoguessing

- very good inference of some characters traits

- and finally quite good ad targeting

EDIT: I tried with a few photos (different people in various settings) and each time I got this: "racial bias towards immigrants" - which was always very false. Intriguing.

EDIT2: different photos of the same person (me) in different settings gives many totally opposed characteristics. Very unreliable, but I guess with several photos (a lifetime's photos in the case of Google) it's another story.
