I try not to give in to the beliefs of weird things that sound very conspiracy like. I always knew the internet was scanned for key words and such since 9/11. I am sure most of it was in the name of National Security, but it is kind of crazy how Google, Facebook, and now At&t are selling our browsing history to allow companies to better advertise to us. Call me crazy, but I feel these are the first steps to a Skynet type software. "Oh, you googled a tv, let me show you all these other tv's with similar features and sized." "Oh a human got mad his computer kept crazy so he threw it out of his window, all humans must be against machines. Activate all 'google controlled cars, trucks, plans, etc.'" I know it is a long shot but I can't help but think if we do not control how smart our software gets this "software evolution" will take place.
