Science and imagination have an intimate relationship. Stories and movies both draw on and also drive forward real research. In transportation, for example, we imagined flight and space travel - and both became reality. In space, we dream of faster-than-light travel and physical teleportation (instant travel!).
If we can't physically teleport ourselves, the next best thing is instant communication - and we are lucky to live in a time where voice, video and even holograms are routine technologies. Interestingly, everyone today has the ability to broadcast live video - yet we still get stuck in traffic, with many taking longer to commute to work than they did just a few years ago. What differentiates the progress of digital communication from that of physical transportation?
