Is it possible to use a person's personal Google data to create their doppelganger? To reconstruct their personality, behavior patterns and hidden desires? A cross-media data experiment makes it possible to experience what kind of insights into our most intimate secrets Google, Facebook, and others already have. In the film, a former YouTube developer, a Google marketer, an expert for personalized advertising and several data protectionists explore the potentials - and the risks - that lie in algorithmic personality detection and behavior prediction. The film exposes how tech companies use the collected data of billions of people to turn our weaknesses, insecurities, illnesses and vulnerabilities to addiction into profit. #documentary #dwdocumentary #technology ______ DW Documentary gives you knowledge beyond the headlines.
