Five times Netflix's Black Mirror predicted the future of tech

Netflix's darkly addictive sci-fi series Black Mirror claims to show the'twisted, high-tech' of the near-future, but several technologies featured in the drama-filled episodes can already be found in our lives today. These include killer robot dogs, a social credit rating system and autonomous pizza delivery. In one of the most memorable recent episodes, 'The Entire History of You,' a contact lens featured a built-in camera that allowed humans to re-watch their memories. The concept is less futuristic than you might think, because Google may be already working on a similar device, while a startup is set to unleash a VR application that enables you to relive your experiences in a digital world, and Snapchat has released a device to capture memories. And let us not forget the second episode in the third series, when an augmented reality tester dies in both the natural and digital worlds.
