"It could. Riding the bus? It could automatically pull up the bio of a person sitting next to you." Google, and hence the NSA and the US of America(thanks to Patriot Act) having the information of who is at every moment at a given bus, restaurant, party in any part of the word.... is kind of creepy to me. With mobile phones they can do it today, but with lots of effort, it draws the battery and I could give my phone to someone else, or leave it on a Faraday box if I want. With cameras pointing to people you have lots of other metadata, like who is kissing or smiling or hugging whom, who is serious with whom. Who is a leader, who is a follower. In essence, it is a spy. It is not amazing, people from secret services regularly kill people from other countries if they consider it worth "national security", like a news reporter that wanted to know too much and know hold information that puts "the country at risk". Talking to people like Arturo Perez Reberte that has been war reporters for decades they tell you very clearly that secret services from the big boys(Russia, US, Israel) have killed some of their friends. Think for a moment how people, specially women preferred to live in cities instead of villages because they were not controlled in everything they did.
