Science fiction writers often seem to use new words or terms for the inevitable next generation of technology, like '3D So-Vi' for television or 'time teller' for clock. The problem is that words have momentum that's hard to overcome. People were referring to "ice boxes" long after they required no ice. I frequently say I'm going to rent a video when I mean a DVD. I've even heard a television referred to as a "picture wireless". If those terms persisted, then "television" and "clock" will, too, and, English being English, the simplest word is likely to win.

PS - But how will you know it's the future unless they have weird words for things?
PPS - I think the jet packs will give it away.
