What Will the Future Be Like?

PBS Airdate: November 14, 2012

DAVID POGUE: Our world is rapidly changing.

Let's say I'm in an unfamiliar neighborhood, and I get lost. Just a few years ago I would have spent hours wandering around. Today, all I have to do is pick up my smartphone. An app like New York Subway shows me if there are stations nearby and even shows me which way to walk to get there.

If I need something translated, no problem, Word Lens replaces the text in my view with my own language! And in the future, will it be possible for us to do this? Get information about anyone in an instant?

A paradigm shift is taking place right before our eyes. The real world and the virtual are merging. It's called augmented reality. And you can experience it with the help of hundreds of apps on your smart phone. But one day soon, companies like Google, the internet search giant, think all this information will be delivered in revolutionary new ways.

BABAK PARVIZ (Google, Inc.): This is Glass, a very different type of computing and communication device.

DAVID POGUE: Think of Google Glass as a wearable smart phone…

Can I try it?

BABAK PARVIZ: Yeah, you can put it on if you like.

DAVID POGUE: …but lighter and quicker to access.

Oh, wow.

Right now Glass is a work in progress.

I can just flick my eyes into this corner, and I see a very crisp screen.

The little square you see glowing here is actually a tiny computer screen.

Google hopes that in the not too distant future it will bring us our email, show us our text messages and provide access to the internet. And the tiny camera here will be a new way to share your experiences with friends.

So, this is wild! So, I'm seeing a beautiful path through a woods. As I turn my head, I'm actually looking around the scene. Oh, I can even look down, up. Wow, those are beautiful.

But Google Glass is just the tip of the iceberg. Researchers, like Henry Fuchs at the University of North Carolina, are developing technologies that blend the virtual and physical worlds, augmenting our reality with the stuff of sci-fi movies.

HENRY FUCHS: So, this is one of the labs, David, that we have set up to work on augmented reality and telepresence.

DAVID POGUE: So, as I understand it, this is like in Star Wars, when Princess Leia gets beam out of R2-D2's head.

Remember that famous scene where Princess Leia records a hologram of herself and sends it to Obi-Wan Kenobi?

CARRIE FISHER (As Princess Leia in Star Wars/Filmclip): Help me Obi-wan Kenobi. You're my only hope.

HENRY FUCHS: That was all special effects. What we hope to develop here is the real thing.

DAVID POGUE: And that's as hard as it looks.

First, I put on these stylish shades.

TECHNICIAN: Is that too tight?

DAVID POGUE: Nope.

Once we're set up, we're ready to roll. We pretend Henry's on vacation, in his beach house in Hawaii, while I'm stuck in my office here in New York. And suddenly...

Wow! If my goggles don't deceive me, that's you sitting across the table from me.

HENRY FUCHS: Wonderful! That's just the effect that we would like.

DAVID POGUE: Wow, so that's crazy. You look, you look the right height, size, shape and angle, as though you were actually sitting right in front of me.

I have to admit, it's the closest I've ever come to having a conversation with a hologram, although the image is far from perfect.

So, this is the Model T we're wearing right now.

HENRY FUCHS: Oh, we're not even Model T.

DAVID POGUE: Not even Model T?

HENRY FUCHS: Oh, no, no. This is like, you know, 20 years before the Model T.

DAVID POGUE: But the technology needed to create this illusion is anything but 20th century. In order for Henry and me to see each other, he's rigged our rooms with a bunch of 3D cameras. They are, in fact, Xbox Kinects. With the help of some sophisticated software, they transport his virtual image into my stunning handcrafted headset. And these little silver balls that make us look like aliens are part of a complex tracking system that pinpoints where we are in space.

There's one serious problem with the video though.

HENRY FUCHS: Yes?

DAVID POGUE: It looks like you're wearing a hideous, obnoxious Hawaiian shirt of some kind.

HENRY FUCHS: Ha ha ha.

DAVID POGUE: In the future, telepresence systems like this one could come in handy. And wearable smartphones, like Google Glass, may give us a new way to access the virtual world.

The question is: will technologies like these, that aim to immerse us even more into a digital world, improve the quality of our lives?

A lot of experts are wary. They say our immersion in technology is already a problem.

Look at kids today: they're listening to music, while texting a friend, having a conversation on Facebook and doing their homework, in other words, multitasking. Can their brains keep up with all this connectivity?

Stanford Professor Clifford Nass thinks they can't, that doing so many things at once is making it harder for them to focus.

And he's devised a test to prove it.

CLIFF NASS (Stanford University): What we're going to ask you to do is to simply focus on a couple of red rectangles and to ignore blue rectangles. This sounds like a pretty easy thing to do.

DAVID POGUE: Yeah, I'm down with this.

CLIFF NASS: And we'll see how you do.

DAVID POGUE: As I start the test, two images containing red and blue rectangles flash on the screen. If the red rectangles move from one image to the next, I press one button, but if they don't move, I press another.

Simple right?

Ah, that changed.

Well it is, at first.

Jeez, there's like 1,500 of them.

But as more and more rectangles appear on the screen, it becomes harder and harder to focus on the red ones and ignore the blue.

Come on.

Criminy.

You completed the filtering task study. You made some careless mistakes. You feel like an idiot.

But, before I can find out how much of an idiot I was, Nass gives the same test to 16-year-old Jordan Ford. Jordan is a proud multitasker and doesn't think it affects his ability to focus at all.

CLIFF NASS: All right, well, let's see how you guys did.

JORDAN FORD (Multitasking Test Subject): All right.

DAVID POGUE: Give it to me straight, Doc. How long have I got?

CLIFF NASS: Well, I'm going to keep you in some suspense. Let's look at Jordan first. So, what we see on this graph is a pretty precipitous downward slide. The more rectangles there were, the worse you did. This is a very, very common pattern we see among teenagers who multitask frequently, because their brains are constantly looking all over the place and trying to process multiple things at once, even when they know they shouldn't.

Now, let's see, David, how you did, and that's this blue line here.

DAVID POGUE: Oh.

I am impressed.

Smoked! Sorry, pal.

CLIFF NASS: Even though you're a heavy technology guy. When you use technology, you do one thing at a time, you really focus on what you're doing. And what we see here is a pretty predominant difference.

So what we worry about here is, Jordan, when you really need to focus attention on something, it's going to be harder and harder.

DAVID POGUE: Parents have been saying, "Quit using X technology, you'll rot your brain" since my grandparents' time. You know, like the cave men were probably, "Quit making fire with sticks. You'll rot your brain," right? It's a chronic thing to be suspicious of new technology, to worry about the effects. So, should we really worry yet?

CLIFF NASS: Well it's silly to say to a child, "Stop using the computer."

DAVID POGUE: Right.

CLIFF NASS: You know, just as it's silly to say, "Stop using fire." But, you know, you shouldn't play with fire when there's dry brush around.

With any new technology, we should be both excited and we should worry 'cause it often brings some negative things, as well. So the question is, how do we balance the two. That's really the critical issue.

SHERRY TURKLE: It's pushing us against a moral imperative, you know? Not every advance is progress. Not every new thing you can do with this incredible technology is better for us humanly.

DAVID POGUE: So where is all this technology leading us? If digital information is becoming even more available to us, and even more immersive and distracting, are we headed to a future where we don't actually learn things anymore? Are we headed for a world, like in the movie WALL-E, where humans are such passive consumers of technology we become dumb and helpless? Is this what the future will be like? Will the Pogues of tomorrow turn into lazy, couch potatoes?

At Maker Faires like this, in the heart of America, folks are determined not to let that happen. Instead of becoming passive consumers of technology, these people are learning to master it. Usually, it's not about building something with commercial value, but using it to express themselves in the most creative ways possible: like Mickey Miller, a high school sophomore from Toledo, Ohio, who recycled scraps from his garage to create a unique form of transportation;…

So what do you call this thing?

MICKEY MILLER (Maker Faire Particpant): Recyclobot.

DAVID POGUE: Recyclobot?

…and kids like these, who join robotics clubs to develop the skills they'll need to invent a better future.

GIRL: When you work a lot with technology, you try to challenge technology, to make it better, to make yourself better.

BOY: After doing this, I felt like I could build whatever I want and decided to take the initiative and build my own computer.

DAVID POGUE: But this is more than just a fun hobby; it's becoming a movement that may reshape our world.

RODNEY BROOKS: I think the maker movement is great, this is the new form of hobbyist, and actually they've got some pretty interesting tools. The makers have taken the best of microprocessors and 3D printers and building it in a way that ordinary people can control them and can do stuff with them.

DALE DOUGHERTY (MAKE Magazine): We're showing them, at a really basic level, that they can control technology, that they can do something with it themselves, rather than just be users, that they can create something and make it do something that they want it to do.

DAVID POGUE: And that's why people are here, taking control over technology instead of being controlled by it, creating a better future from the ground up, a future of their own making.

So maybe there's hope.

RODNEY BROOKS: There's a lot of hope.

DAVID POGUE: Excellent.

How hard is it to predict
the future of technology?
Over a century ago,
Thomas Alva Edison
perfected the lightbulb…
…and predicted a bright future driven by electricity.
He also predicted we'd figure out
how to transform iron into gold.
We'd ride around in golden taxis.
Our houses and furnishings would be gold, too.
(If it were too soft…
…we would opt for steel.)
Bright future, indeed.
