Does the accelerating pace of technology change the way we think about the future? It's said that science fiction writers now spend more time telling stories about today than about tomorrow, because the potential of existing technology to change our world is so rich that there is no need to imagine the future - it's already here. Does this mean the future is dead? Or that we are experiencing a profound shift in our understanding of what the future means to us, how it arrives, and what forces will shape it? Presenters Timandra Harkness and Leo Johnson explore how our evolving understanding of time and the potential of technological change are transforming the way we think about the future.
