1) A teleporter. An environmentally friendly method of getting anywhere in the world in no time at all. No more crowded airports, sardine-can aeroplanes, or bus-rides that take forever to get anywhere at all.
2) A space gateway to the stars. I’m not saying it’s going to be easy or cheap, but we should be making friends with our galactic neighbours, not hiding out in the basement.
3) An internal communication device with a ring tone that only the person being paged can hear. Also, an internal MP3 player, radio, and hi-fi. Best done soon, before I give in to the impulse to start dunking various bits of electronic wizardry in the nearest body of water I can find.
4) Cities that hover in the sky. That way, the marshlands can stay untouched, and if pipes start to leak, there’s no worries about flooding. True, there might be a short-term increase in the number of birds impacting against buildings, but that’s why Survival of the Fittest became the evolutionary rule. Also, (a) pigeons are not on the endangered list, and (b) statues everywhere could breathe a figurative sigh of relief (unless, of course, they were the termination point of the pigeon’s flight, in which case they’d do well to keep their mouths closed if they didn’t want to choke on the feathers).
5) Fold-up cars, so that parking issues become a non-concern.
