Now, thanks to an algorithm developed by researchers at the University of Birmingham, your smartphone may soon be able to make accurate educated guesses as to where you’re going to be in 24 hours time. And here’s the dirty trick responsible for the algorithm’s future-telling powers: it spies on your friends and connects the dots where necessary. In a sample of 200 people, the system was on average less than 20 meters (66 feet) off when trying to predict where a person is going to be in 24 hours time. When the same system was stripped of the social component, the average error grew to 1 km (0.6 miles)."
