The film, Back to the Future II, released in 1989 made a series of outlandish predictions about 2015, the year its key characters travel to from 1985. Although several of the film's predictions, like video calls and wearable technology, came true. Back to the Future II shaved the pit falls of making long-term forecasts. The world of 2015 was one of hoverboards, flying cars and power clothing, and instead we got Snapchat and selfies. Several experts have made their predictions about what the world of 2045 will look like. Alex Ayad, head of Imperial College London's Tech Foresight practice forecasts that people will be able to purchase high-quality emotions online. Emotion-sharing experiences are the latest fad in 2045. Imagine your friend at a music festive I can post a photo on Instagram and with it comes bundled a faint twinkling of what she was feeling right there in that moment, so you too can share emotionally in her social experience. Recently, techniques for direct brain stimulation, like optogenetic, have made it possible to not only read but also write information into single neurons. At the moment data transfer rates are still very slow, the best we can do is a few bits per second, but this could well increase to kilobits maybe reach broadband speeds by 2045.This means the range of human perception could expand.

Our cities will be made from living, dynamic materials that respond to the environment. In 30 years. Tall buildings made of glass and twisted steel will be seen as relics from a bygone era. In the same way we think now of 1970s concrete tower blocks: ugly, outdated and unfit for contemporary purpose. The urban environment of 2045 blends architecture with living materials that are mouldable, adaptable, responsive and disposable.
