October 21, 2015, seemed like an awfully long way away when Marty McFly and Doc Brown time-travelled there in 1989’s Back to the Future Part II. Now it’s two years in the past. Scary.
The film made numerous predictions that were pretty much spot on, from the use of drones and fingerprint scanning to tablet computers, hands-free gaming, wearable technology and video calls. Even Marty’s hoverboard is almost a reality. Lexus, the Japanese car manufacturer, has even unveiled a rideable prototype.
