We love to imagine the future. But why is dramatic future technology always just around the corner, and never a reality?

For decades we've delighted in dreaming about a sci-fi utopia, from flying cars and bionic humans to hoverboards; with driverless cars first proposed at the 1939 World's Fair. And why not? Building a better world, be it a free-flying commute or an automated urban lifestyle is a worthy dream. Given the pace of technological change, nothing seems impossible anymore. But why are these innovations always out of reach? Delving into the remarkable history of technology, The Long History of the Future also looks at what lies ahead, showing how the origins of our technology may provide insight into how it realistically evolves. You may never be able to buy a fully driverless car, but automated braking and steering could slash collision rates. Smart cities won't perfect city life, but they could help bins be emptied on time. Hyperloops may never arrive, but superfast trains could fill the gap. Looking to the future, Nicole Kobie demonstrates how despite our belief that current technology is the best it could ever be, the future always proves us wrong, and there is much to look forward to.
