Whether you’re stuck on a jetpack, looking out for a superhighway of flying cars, or just waiting for a battalion of homicidal robots to do battle with in the depths of a megacity, we want to know about the technology that would make you feel like the future had finally arrived.

Tell us in the comments what the technology is and what about it makes it seem so far away. Be sure to tell us just how far off (or close) you estimate it be from our own present.
