6 Sci-Fi Gadgets from TV & Movies that Actually Exist (Infographic)

Sometimes you can't expect a new technology to catch on very fast. For example, the moving sidewalks we all use at those huge hub airports date back to the 1893 World's Columbian Exposition in Chicago. But until airports started to pick up on the idea, bleh, no big deal.

I'm sharing this because I don't want you to be too disappointed if your wireless carrier doesn't start to offer an "Unlimited Holograms Plan" in the very near future.

And even if your next door neighbor is your go-to guy when you need to borrow a tool, don't expect him to have a suction-cup vertical wall scaler anytime soon. There's a good chance that next fall you'll still have to borrow his old-technology ladder to get the leaves out of your rain gutters.

However, let's hope we start seeing self-driving cars in the next year or so. People are probably more likely to get one of those than they are to stop sending text messages while they're driving. I'm pretty confident a computer would be a safer driver than most of the people I pass on my way to work.
