This documentary about Big Data (by John Fothergill – BBC Productions) makes clear how fast our world is changing. Through the use of the huge and growing amount of data released from all digital activities, one can predict processes to great accuracy. Human behaviour in particular. Our mobile phone feeds the flood of data continuously. Everything is saved. And the consequences of all that information are enormous. Big Data was broadcasted by BBC Horizon and is a film of about one hour. This film makes clear that the technology allows that we may collect and store crazy amounts of details, that reveal patterns we could see never before. So we’ll unravel the predictable future.
