(air whooshing) - How on Earth did a language with tens of thousands of characters fit onto this keyboard? - [Narrator] Here is a world of communication, tailored for your needs of today and tomorrow. - [Narrator] What really accounts for China's meteoric rise as a major global power? - This is Shenzhen. It's a city in the south of China. I've actually been there. But back in the 1980s, this was just a sleepy fishing village with less than, like 100,000 people. Today, it is home to 12.5 million people, a giant metropolis with huge buildings and home to some of the largest tech companies on the planet. This city is emblematic of China's technological rise over the last 40 years. It's an explosion in technology and development that has really never happened before in human history. From an agrarian society to a technological powerhouse in just a couple of decades. - That's fast. - This almost didn't happen. China almost didn't become the technological powerhouse. And what held them back is something I have thought about a lot, which is this keyboard. This keyboard has like, 80 or so keys, and the Chinese language has like tens of thousands of characters. So how did they fit their language onto this keyboard? To answer that question, you have to dive deep into modern China, into Chairman Mao, into the divide between Taiwan and mainland China, who despite speaking the same language use very different typing methods, all because of geopolitics. It's a story of how China took a keyboard that was developed for a vastly different language system and mastered it, mastered it better than we did here in the West. It's a fascinating story of culture and history and technology, and I want to share it with you. - [Narrator] Here is China. - [Narrator] It's become a keystone of national economic policy. - [Narrator] A large part of China's population lives in large cities. - [Narrator] I really don't quite understand everything that's happening. (upbeat music) - To understand how Chinese speakers type on a keyboard like this, I talk to my friend Mangle Kuo, who's currently in quarantine in Taiwan. - I just came back and quarantine in Taiwan's quarantine hotel. - Oh, my gosh. Wow. Mangle has lived in both China and Taiwan. He's technologically savvy and helped me understand how people type, not just on their keyboard but on their phone. - So basically growing up as a Chinese or Taiwanese, you have to learn how to write those characters. That's kind of the first thing first. And then you learn the, like the pronunciation system behind all the characters. And in China, that's pinyin, and in Taiwan, that's zhuyin. - So let's break this down. Most languages are written with an alphabet. Each letter in that alphabet represents a sound. And when you string those sounds together, you make a word. It seems so intuitive as if like this is the only way to do it. But in Chinese, - There's another way. - Chinese uses complex characters for each word, so every word is a character. Each one of these characters represents a different thing, an object, the feeling, a concept, a verb. All in all, there're upwards of 70 or 80 thousand of these characters. This system was just fine. It worked in China for a really long time because you can use a brush or a pen to write stuff out. - I like that. It's like if it ain't broke, don't fix it. - This is the qwerty keyboard. It's called the qwerty keyboard because I mean, just look at it. This is the mechanism to which people not just communicate with each other, but code the world, the software and programs that we all use all the time. When this started to take over, China had a real problem. Listen, I need to just pause to tell you about something which is that investing money is hard, sometimes. And honestly, I'm like in my 30s now and I just sort of learning the art of investing and not really. The sponsor of today's video is the company called Acorns.

It's a fantastic way. So thank Acorns for sponsoring this video. Let's get back to the story. They had to figure out how to fit this onto this, and fast, because the world of computing started to explode in the 70s, and 80s, and 90s. - Hello, I'm Bill Gates. - Here in the United States, the qwerty keyboard was a very natural tool. We were able to use our alphabet and our symbols that we all are very used to, to develop programming languages so that we can make software. And soon, more and more computers were showing up into American homes. (pop songs from the '80s) - [Narrator] The Commodore 64 now in a family pack. - Meanwhile on the other side of the planet, China, a country of almost a billion people only had 3000 computers in the entire country. They were so far behind the West when it came to computer literacy. The Chinese government begins to freak out. And it's like, guys we're getting absolutely destroyed by the West because of this whole computer thing, and you're telling me that is because we can't fit our language onto this keyboard? Are you kidding me? What we're gonna do about it? So the Chinese government made this a huge priority. And they finally started to develop somethings that worked. (door opening) - I got it. (audience laughing) - The first major system of typing used the qwerty keyboard to build the shape of the characters. - We call it Cangjie. - Cangjie, and it was pretty darn complicated. - It's basically like, puzzles. - Like Legos. - Yeah, kind of, like a brick. You just put them together. I can write basic characters using that. - The system was clever but it was complicated and not very fast at first. Luckily, China had a wild card up its sleeve that will help get Chinese speakers typing on a qwerty keyboard. It had to do with this guy, Chairman Mao. - [Narrator] The great Chinese Chairman Mao Zedong. - History time, here we go. - [Narrator] The Communist Party's propaganda machine portrays the Chairman's Great Leap Forward as a dazzling success. - Mao was really bullish about modernizing China. And one of his pet project was scrapping the entire Chinese character system and replacing it with a Western-style alphabet that sounds out Chinese words, sort of like how we sound out our English or Italian or Spanish words. Now it was like learning thousands of Chinese characters is hard and complicated so why don't we just have a Latin or Romanized alphabet like the rest of the world. So by 1949, Mao was like ready to roll, scrapping the entire Chinese writing system in the name of a Roman alphabet. But then, one of its close buddies, former Communist dictator Joseph Stalin, convinced Mao not to totally kill off the Chinese characters. Stalin was like, dude, don't, dude you're gonna regret it. And Mao was like, fine. So he kept the Chinese characters as the main writing system but for teaching literacy in school, he developed a written alphabet called pinyin. - Pinyin, P-I-N-Y-I-N. - Where you can use the Roman letters to spell out Chinese words by the way that they sound. So right now you're typing out this sentence in Romanized charcters in the way that it would be phonetically spelt in Roman, like "wo" is W-O, right? - Yes. - Okay. So you typed it all out, - Yeah. - and down there it renders it, okay. Wow. So now if you want to write the word "beef", which is "niu-rou". - How to say "beef"? - I think "niu-rou". - "NIU-ROU" - I've no idea, "niu-rou", "niu". - "NIU-ROU" - "R-rao, niu-rao". I've no idea. Instead of memorizing these characters which means "beef", you can just spell it out by the way it sounds. This romanization of Chinese, again it's called pinyin would become really helpful years later when the Chinese government is trying to figure out how to get people to type on Western computers. But wait a minute. We can't go on before we mention a little bit of geopolitics. (canon firing) Okay, it's 1940s. Mao and his Communist revolutionaries are taking over mainland China in a bloody revolution and civil war. And the Chinese government that they overthrow and are fighting with, end up losing and retreating to an island nearby called Taiwan to continue with their non-Communist version of China. And they both think that they're the real China and they start this war that has never stopped and they're still fighting this war and they both think they're China. Anyway, that's absolutely a story I want to tell but I'm not going there. Now again blinders, we're talking about qwerty keyboards. - If we're trying to figure something out, now we need to focus, okay? - So you have this "two Chinas", the Communist one, and the non-Communist one. Mao is pushing the Romanized alphabet in the Communist version of China. And Taiwan is like, no, this Romanized pinyin thing is an invention of the Communist Party, and a total sell-out of the Chinese traditional writing system, no way. But Taiwan is secretly like, we loved the idea of having an alphabet for our Chinese language because it made it a lot easier to teach literacy. So they adopted an alphabet, but it's not the pinyin, Romanized alphabet. It is an old alphabetic system that was developed in the early 1900s. - It's zhuyin. They did it before pinyin. They're completely newly-invented a set of symbols for this purpose. - Wow. That is wild. So because they hated their Communist enemies, Taiwan rejected the Romanized alphabet that Mao was pushing and stuck with this traditional alphabet that had been developed a few years earlier. And that's still how it is today. (woman speaking Chinese) So this gets to a pretty satisfying answer to the question of this entire video which is how do Chinese speakers type on a qwerty keyboard. The answer is, if you go to mainland China you're going to see keyboards like this. People in mainland China use this keyboard to type out the sounds of their words, and the computer takes that and renders it into Chinese characters. If you live in Taiwan, you'll see a keyboard that looks more like this, but you basically do the same thing. Use these characters to type out the sounds of the word and the computer will render it into a Chinese character. Both of these are new writing systems that were developed in the past 100 years to help Chinese speakers spell out their words and move away from a character-based system. - [Narrator] Now what are the key features that you think should be in an ideal laptop. - [Woman] Standby for the software transmission. Better start your recorder now. - Okay, back to our timeline here. It's the '80s and '90s. China is starting to really adopt technology and they're using these typing methods to use the qwerty keyboards to actually participate in the computing world. But they're still lagging so far behind the Western world. They're way slower in their typing so the Chinese government went back to the drawing boards and was like, how can we make it faster. And boy, they found a solution in the '80s that will change everything. (woman speaking Chinese) And this is the work that's kind of juicy, in my opinion. This is the part that is like, I don't know, really helps me to understand how people type today. You know when you go to Google and you start typing a sentence, and it fills out the rest of the sentence for you, or even on Gmail these days, like I'll be typing and suddenly it'll like predict what I want to say. It's pretty cool. It's not life-changing. It's sort of like saves me maybe a couple of milliseconds every day. In China, this technology of predictive text, predictive typing, was life-changing because regardless of what method you use to start building your characters in the computer, the computer now starts to guess what characters you want to type. For example, let's say someone is using one of these systems that we're gonna use to build these characters, and they type this character. This is the root of a Chinese word and it means "water". The computer sees this and says, okay, you just typed "water". There's a bunch of characters that are derived from this root, this "water" root. For example, here's the one for "river" or maybe you actually want this one which is the word for "wash". So if you just type water, you can look at these options and decide which one you want. This was an algorithmic, predictive typing system that was happening in the late 1980s in China, three whole decades before anything similar surfaced in the West. And it is this technology of predictive text that changed everything for China. - [Narrator] Before computers, there was no practical way to type the thousands of characters called kanji. To deal with the complexity of these symbol words different systems have been adopted. - They started to refine this algorithm to make it more and more clear that as soon as you start typing anything, the algorithm says, do you want to do this, or this, or this, or this? I mean I've been watching a great deal of competitions, typing competitions. (woman speaking Chinese) This is the thing in China, and if you zoom in and look closely at this competition, you'll see that as soon as these competitors start typing a pop-up box comes up, giving them an algorithmically generated menu of options that predicts what they're trying to type. So typing in Chinese is as much about choosing from this predictive menu as it is about pressing the keys. It is a combination of both. And this competition has pushed developers to make better and better predictive algorithms so that people can communicate very efficiently using the keyboard. So how fast are these people typing right now? Well, the average English speaker can type at around 43 words per minute. I work on a computer all day so I'm probably more like 60, 65 words per minute. There is an English typing competition in Las Vegas and the typists here are mind-blowing 163 words per minute. But if you head back to these guys, these people are typing at a score of 242 words per minute, four times faster than I can type, and almost double what they're typing in English at the best competition in Las Vegas. Whoa! - Wow, that's fast. - Yeah, it's fast. - So China used this technology that was developed in the West mainly designed for languages that are very different than Chinese, and they mastered it, but guess what? The Chinese government still has the need for speed. They're like, how can we make it faster? So predictive typing in China went from letting you start a character and predicting what character you want to choose, to then going to seeing what character you just put and predicting the next one, the next word in the sentence that you want to say. And now in the last few years they're pushing it to the next level, which is Cloud-based predictive texting. - A cloud? - Again, the closest thing we have in the West is like the Google Auto-complete. You go to this search engine. You start typing and the Internet is like, a lot of people are searching this so we think you're searching this, too. But imagine, instead of just a search engine, imagine this concept for everywhere. As you're typing your WORD documents, as you're texting your mom, anywhere in the digital space that is connected to the Internet is now feeding you sentences that they think maybe you want to say based on an AI-generated web of information of what everyone else is texting, and emailing and writing. So an example of this, let's say that there's a Chinese movie star that just got into a big car accident. It's all over the news and everybody is talking about it. You've never typed this movie star's name before but as soon as you do start typing it your phone starts talking to the Cloud and not just the Internet but other people's text messages. So then the algorithm says that I think you probably want to text about this movie star and the car accident. And this seems like a great time-saving technology that helps Chinese speakers type. - It's a good idea. - But just imagine some scenarios here. Let's say that you're not writing about a movie star and the car accident. But let's say instead you are texting a friend about June 4th 1989, Tiananmen Square. - [Narrator] The noise of gunfire rose from all over the center of Peking. - [Narrator] China is a nation at war with itself. - There's one major company that owns the software. This one company determines most of what shows up in predictive text. And in a country where there's not a lot of hesitation to control citizens' access to information, it's not far-stretched to see how subtle manipulation can start to occur with this Cloud-predictive text. Algorithm deciding sort of what should go next. For example, if you type in "Taiwan is China", the algorithm will suggest to you "Taiwan is an inseparable part of China". Anyway, this is not a major problem right now. And I'm not saying that the government is manipulating every individual in China with predictive text. All I'm saying is that, the story of how Chinese speakers have been able to type on the qwerty keyboard is the story of really clever and amazing technological advancements, and a huge part of that has been predictive algorithms. And all I'm saying is that algorithmically presented information can lead to some dangerous outcomes in terms of making people think a certain way. But at the end of the day, let us just end on the fact that China has developed a really amazing technology for getting their language into the computer, and by doing so, have been able to pass any typist in the West, helping fuel the rise of China as a technological powerhouse. (mysterious music) That's the story here and I really learned a lot. Thank you all for watching. I will see you soon. And thanks for being here.
