Two ways you'll know the future has arrived, according to the gospel of The Jetsons: we have mouthy robot servants to manage our lives, and we all drive flying cars or have personal jetpacks.
Well, I don't see any robots around (at least ones that don't scare the bejeebus out of me by tripping and falling squarely into the uncanny valley, a la this specimen) , but jetpacks and flying cars are getting closer to becoming a reality.
Case in point: the Transition. I say getting closer, because to me this still looks mostly like a plane (although it becomes more VW-bug like when the wings are folded up). It's only a mere $10,000 to be put on the waiting list behind 70 other prospective futurists, and a cool $194,000 expected sticker price. Added drag: total fuel hog. So yeah, we're closer but not quite there yet. Show me one that runs on renewable energy, and maybe I'll get in line.
