10 Futuristic Inventions We're Still Waiting For

We may soon be getting self-driving cars, but—much to the chagrin of Back to the Future fans everywhere—still no hoverboards. Time lists 10 more futuristic predictions that haven’t exactly panned out:

• Jet packs: OK, so these exist, but you probably can’t buy one. Popularized in a James Bond flick and, of course, The Rocketeer, in real life these remain available only to astronauts.
• Meal pills: Remember when George Jetson just took a pill instead of sitting down to dinner? If we tried to do that, we’d need to swallow at least a half-pound to get the required amount of calories each day.

• Flying cars: Speaking of Jetson, he had one of these, too. And there’s good news! At least one program is looking into creating one, although it sounds more like a plane than a car.
• Teleportation: Physicists have looked into whether this would be possible using wormholes, but so far, Scotty cannot yet be beamed up.
• Intelligent cyborgs: There are humans with “cyborg” parts, sure, but we have yet to create the Terminator.
