The all seeing eye

What does Google know? What can it guess? Well, it seems just about everything. “One of the things that eventually happens … is that we don’t need you to type at all,” Eric Schmidt, Google’s former CEO, said in a moment of candour in 2010. “Because we know where you are. We know where you’ve been. We can more or less guess what you’re thinking about.” He later added: “One day we had a conversation where we figured we could just try to predict the stock market. And then we decided it was illegal. So we stopped doing that.”
