Boy：top, efficient, convenient and holy Girl: intelligent, novel, flexible and objective Boy: Welcome to the column of technology information. I'm Johnny. Now, let me introduce my guest hostess------Bramble, also in the program the Amazing ones. Girl: Hello, everyone. I’m Bramble and I’m pleasant to be this week's reporter. Boy: Welcome again! Bramble, have you ever seen the movie Back to the Future Part II? And if so, in the movie,what exactly impressed you most? Girl: i have heard about this movie the other days, it was made in 1985, but present the story happened in october, 2015. just several days ago! but i got no time to see it recently. can you tell me something about it? Boy: Exactly, it is about time-traveling to 2015 from 1989 where the world had changed a lot. The most impressed scene I think must be Marty answers a video call on them before sending the call to his dad on the living room TV screen. Even nowadays it still seems to be an amazing thing. Girl: yep. and i know there are many other unbelievable things in the film, so why not come to today’s topic to see whether these imaginations have come to reality or not? Boy: All right. Let’s come to the topic of 'Back to the Future Part II': science fiction vs. reality. Boy: If you came of age in the late '80s, there's a good chance that Back to the Future Part II was a formative film that helped inform your idea of what society might look like in the not-too-distant future. BTTF creators Bob Gale and Robert Zemeckis certainly weren't trying to predict the future as much as they were trying to build a world that worked with their story. And in fact, the entire trilogy features less than 40 minutes of time in 2015. But that doesn't mean this limited glimpse at the future wasn't thrilling and hilarious to moviegoers in 1989. Now, it's just fun to look back and see what, if anything, they got right -- particularly today, the day that Marty and Dr. Emmett L. Brown traveled forward in time to. We can now finally judge how the fictional world of Hill Valley in 2015 matches up with reality. Girl: Flying cars Let's get the big one out of the way first: No, we're not even close to the flying-car technology seen in Back to the Future Part II. Where we're going, we still need roads, unless we're torturing ourselves with commercial air flight. The good news is that while our cars are still strictly land-based, they're becoming increasingly less reliant on gasoline. The Mr. Fusion system that powers the DeLorean's time-travel capabilities with garbage in the second and third BTTF films shows that Gale /geil/and Zemeckis /zdaoemakis/were thinking about alternative energy, but we don't know what the main power source for 2015's flying cars is. Here in reality, electric vehicles are becoming more commonplace and getting better every year. Couple the advances Tesla is making with hydrogen-powered cars like the Toyota Mirai and there's no question our automotive technology has made great leaps since 1985. A car that's only emission is water is a lot more important to the future of transportation than one that can fly above traffic. And that's not even mentioning self-driving cars, technology that could make driving a lot safer than it is today -- there's no sign of any such vehicles in the BTTF universe at all. There's still no word on replacing our ancient license plates with barcoded versions, however. Boy: Hoverboards If flying cars were the most iconic part of Back to the Future Part II's vision of 2015, hoverboards are right behind them for capturing our imagination. The hoverboard that Marty "borrows" from a little girl ends up being an essential tool for many of his adventures over the second and third films -- he wouldn't have gotten back to 1985 without it. Hoverboards aren't commonplace toys yet like they are in the film, but they're getting a lot closer to being a reality. Lexus showed off a prototype recently, and last year we got to take a $10,000 hoverboard out for a spin. For now, we'll just have to keep hoping that hoverboards make it to the mainstream sooner than later. Girl: Fashion Much like hoverboards, the fashion tech in reality hasn't quite caught up with Back to the Future Part II just yet. Marty's self-lacing Nikes were easily the most memorable future fashion shown off in the movie. Nike tried to capture that magic back in 2011with a pair of Nike MAGs that didn't lace themselves, but there have been plenty of rumors about a self-lacing /leising/ pair actually being released this year. Future day has arrived and Nike /naiki/ hasn't yet dropped that bombshell, so we're still waiting for this one to come true. Boy: Eyewear Google Glass may have crashed and burned thus far, but there's still plenty of interest in augmented reality and virtual reality here in the real world. The same goes for Back to the Future's 2015. Doc sports a sort of digital binoculars that overlay data on top of the display, and he also wears a pair of opaque metallic shades while flying that seem like they should block his vision -- but they don't. Marty's kids both wear some sort of augmented reality goggles when hanging around their home (even at the dinner table!). We don't get a lot of details on what exactly those goggles are for -- all we know is that Marty answers a video call on them before sending the call to his dad on the living room TV screen. Furthermore, video calling seems entirely commonplace in BTTF's 2015. It seems like the default way of communicating, with voice-only calls apparently phased out for the most part. Of course, video calling is quite popular here in the real 2015, but we're even more addicted to text-only communication at this point. Girl: In the home Video calling is far from the only forward-looking technology in Marty and Jennifer McFly's future home -- there are plenty of other smart home innovations that should sound familiar. It starts at the front door, where your thumbprint is used to enter instead of a doorknob. We may still mostly use locks and keys, but you can get your hands on a doorknob and lock that you can open with your finger. Marty's home also adjusts the lights and temperature for him when he enters, something similar to what many smart home systems promise. Perhaps the thing that's most notable around the McFly household is how much voice control has been integrated into the home. The TV, phone, lights, air conditioning, kitchen appliances and more all respond to human speech. We're getting there with Siri, Cortana, Google Now, Alexa and all the rest, but we're still not quite to the point where we can just bark commands from anywhere in the home and expect our wishes to be granted. The house also features a "video shade" over the windows that projects whatever sort of image you want outside. Not something we have yet (nor something that makes a whole lot of sense), but we do sometimes Chromecast fireplace scenes to our TVs. It's not all that different. Marty's kitchen is also advanced in some ways that we don't have, most notably the food machine that takes a tiny little pizza and blows it up to a fully cooked pie in just a few seconds. Boy: Life in 2015 Back to the Future Part II is filled with plenty of other small tidbits about life in 2015, some of which I surely wish were real. Doc notes that the justice system is incredibly fast and efficient now because they abolished all lawyers, something that makes me wonder just what other massive changes to the justice system may have taken place. Weather forecasts are even better and more efficient as well, with up-to-the-second predictions routinely coming true. It's something that causes Doc to wish that the post office were as efficient as the weather service. It sounds like the good old USPS is just as maligned in the BTTF universe as it is here. When it comes to pop culture, BTTF does a good job at predicting the sequel-itis that plagues Hollywood -- a giant 3D ad for Jaws 19 nearly scares Marty out of his self-lacing shoes. We're fortunate not to have 19 Jaws films, but Robert Downey Jr. has played Iron Man in six different movies in the last seven years or so. And we're in the middle of a world in which reboots on film and TV are incredibly commonplace. The idea of Jaws 19 doesn't seem so laughable now. Girl: actually i guess human can never predict what kind of new technology will come to reality, and how it will change our life. Boy: I agree with you. But since time is limited, it’s time to say goodbye. If you like our column, please refer to HZAUERSTATION on wechat. Goodbye. Girl: See you next week.
