Scary bloke. But it's possible to worry too much. e.g. Human eye witnesses are reliably crap, and currently most electronic ones are too. You could probably construct a reliable model of how someone looks with a good deal fewer than 14 pictures... but in a world of billions, how useful is that going to be? Before you factor in the effects of powercuts etc.
What worries me most is his assumption that attempting this kind of cataloguing of the human race, because "governments will demand it", is somehow right and good. Though it explains a lot about Google's involvement with China.
