About This Episode

The episode traces how China grappled with the challenge of fitting its logographic writing system into Western-designed computers and keyboards, focusing on Professor Wang Yongmin's Wubi input method that decomposed characters into components for fast typing. It connects earlier debates over abandoning Chinese characters, the proliferation of competing input methods, and the later shift to pinyin-based phonetic typing with broader political and cultural consequences. The story then explores how predictive and cloud-based input, as well as the QWERTY effect, show that our writing tools now subtly shape our language, behavior, and even thought.

Quick Takeaways

  • China initially faced an existential technological barrier because its character-based writing system did not fit easily into early Western computer hardware and memory constraints.
  • Professor Wang Yongmin developed the Wubi method by decomposing thousands of Chinese characters into about 125 basic components that could be mapped onto a standard QWERTY keyboard.
  • Earlier, Chinese-character typewriters and language-reform movements nearly led to abandoning characters altogether in favor of alphabetic systems.
  • After Wubi, thousands of competing Chinese input methods emerged, many incorporating early forms of predictive text and auto-completion well before similar features became common in English computing.
  • The state-backed shift to pinyin-based phonetic input supports linguistic unification but accelerates the loss of handwritten character knowledge and regional spoken varieties.
  • Typing competitions in China show that shape-based systems like Wubi can still outperform phonetic input in maximum speed, even though they are now relatively niche.
  • The QWERTY keyboard's arbitrary layout measurably influences people's preferences for letter patterns and even baby names in Western countries.
  • Cloud-based AI input systems in China now suggest words and phrases based on aggregate data from millions of users, raising questions about how much our tools are beginning to co-author what we write.

Podcast Notes

Intro: AI race and historical technology competition between U.S. and China

Latif frames current AI arms race with China

Recent headlines focus on U.S.-China competition over AI and high-tech leadership[0:12]
Latif says technological leaders tend to lead the world, emphasizing perceived need to 'win the race' in the U.S.[0:17]

Connection to an earlier tech race: Chinese computing and keyboards

Latif introduces an older arms race from the 1970s-80s over a now-ubiquitous technology: how to type Chinese on computers[0:32]
China at that time was on the verge of being left behind technologically and had to find a way to catch up[0:52]
Latif says this earlier story helped set the stage for the current AI situation[0:58]
He hands off to senior producer Simon Adler and the episode 'The Wubi Effect'[0:22]

Coffee shop comparison and hidden cultural difference in typing

Observation of QWERTY use in a New York coffee shop

Jad and Simon go to a hip coffee shop in lower Manhattan with exposed brick and Edison bulbs[2:03]
They count multiple laptops and confirm everyone is using a standard QWERTY keyboard in the same way[2:27]

Imagined comparison with a Starbucks in China

Simon wants to contrast New York with a Starbucks in Shenzhen and pitches a reporting trip[2:33]
Travel to China becomes difficult, so they hire local reporter Yang Yang instead[3:13]

Yang Yang's report from a Hong Kong Starbucks

Yang Yang describes a large Starbucks in Hong Kong with about 50 people and around 30 laptops or tablets open[3:21]
Everyone is typing, writing, and browsing using QWERTY keyboards physically similar to those in New York[3:49]
Key difference: although the keyboards are the same, people use them in many different ways to type Chinese[4:07]
Example: the Mandarin word for dog (gou) could be typed 50 different ways across 50 people, even if they are all typing the same word[4:02]

Introduction of historian Tom Mullaney

Tom Mullaney, professor of Chinese history at Stanford University, explains that in theory there are infinite ways to type Chinese on a QWERTY keyboard[4:15]
He calls this observation a doorway into a 'grand mystery' about technology and Chinese writing[4:21]

Why Chinese is hard to fit into computers

Fundamental differences between English and Chinese writing systems

In English, 26 letters represent sounds, and written words show how they are pronounced ('B-I-G' spells 'big')[6:25]
Chinese characters are not phonetic letters but visual units where components form pictures or concepts[5:51]
• Example: a 'person' component next to a 'tree' means 'rest'; three 'tree' components together form the character for 'forest'
Chinese writing dates back at least 3,000 years, with early examples found on artifacts in Professor Wang's home province[6:16]
There are over 70,000 Chinese characters, each a unique visual representation of a word or idea[5:51]

Hardware and memory constraints of early computers

In the early 1970s, computers had very limited memory-only a few bytes, not enough to store even one modern email[10:17]
Available memory on commercial computers could not store the full Chinese character set[10:28]
Dot-matrix printers assembled letters as 'paper pixels' using small needles that struck the paper[10:44]
• Chinese characters require far more dots than Latin letters, but printer pins could not be made smaller without bending or breaking due to metallurgical limits
The Latin alphabet was effectively baked into the physical design of computers and printers, making it hard to adopt them directly for Chinese[11:30]
Tom frames this as the English language being embedded in the 'matter and materiality' of machines[11:30]

Political and economic stakes for China

Chinese leaders saw computing as crucial for the economy, warfare, and communication, but the country was lagging with only about 3,000 computers for nearly a billion people in the 1970s[12:24]
Limitations forced China to conduct and tabulate its census with pencil and paper well into the 1980s[12:10]
There was a fear that if China could not 'computerize Chinese' or 'Chinese-ize computers,' it would be left outside modernity[12:22]

Background of Professor Wang Yongmin and his mission

Wang's early life and education

Wang was born in the 1940s in a small rural village that grew wheat and corn; his father was also a carpenter[6:16]
His family was extremely poor and could not afford clothes for him, making schooling feel like a precious opportunity[5:51]
Wang studied very hard and says he was number one in his class from first grade through university[6:51]
He attended the University of Science and Technology of China, described as roughly equivalent to MIT[5:39]

Placement in a top-secret defense research institute

After graduation, Wang was assigned by the government to a highly classified national defense research institute in a remote district[7:35]
Even local residents did not know what was being done there[7:39]
The institute's mission was to build computers, a task intertwined with national strategy rather than just engineering[7:26]

Wang's first encounter with a Western computer and the core problem

About eight years into his research, Wang first saw a full Western computer in a local printing shop and was amazed[12:54]
On seeing the Latin-letter keyboard, he asked how 70,000 Chinese characters could be typed with only about 70 keys[13:44]
He realized the magnitude of the problem: fitting a vast non-alphabetic script onto a limited keyboard[13:24]

Fears that computers would destroy Chinese characters

Consensus among many experts at the time held that Chinese characters could not be used efficiently with computers[14:19]
There was a saying that 'computers are the grave diggers of Chinese characters'[14:07]
Prominent voices, including Mao, argued for abolishing character-based writing or adopting an alphabet like Esperanto or English to modernize[14:18]
The State Commission on Language Reform was formally examining how to replace Chinese characters[14:49]

Wang's sense of destiny and commitment

Wang felt it was his fate or destiny to find a way to type Chinese and save the character-based script[15:07]
He believed that if he failed, Chinese culture would end with the loss of its writing system[15:14]
He describes committing himself with 'no return, regardless of life and death,' highlighting how high the stakes felt to him[15:27]

Historical precedent: Chinese typewriters and earlier script crisis

China's first encounter with typewriters and calls to scrap characters

In the 1910s, as China emerged onto the world stage, visitors saw Western offices filled with fast typewriter typists[20:38]
• Historian and collector Martin Howard describes a visitor to Ford's headquarters hearing a cacophony of hundreds of typists
Typewriters transformed English communication due to speed, legibility, and ability to produce many copies[21:15]
China saw the productivity advantages and felt compelled to adopt similar technology[22:05]
As early as Mao's era, some leaders advocated replacing Chinese characters or adopting an alphabet so keyboards could be used efficiently[22:34]

The Chinese character typewriter

A successful Chinese typewriter existed that looked unlike Western typewriters and had no keyboard[22:46]
The machine used two levers and a tray bed full of metal characters, which were moved into position and swung up to strike the paper[23:09]
• The mechanism resembled a jukebox arm grabbing a record: a selected character was lifted, inked, struck onto paper, then returned
Typing speed was roughly half that of an English QWERTY typewriter, but it worked well enough to prevent the abandonment of characters[24:00]
For Wang decades later, this typewriter proved that technology could be bent to fit Chinese rather than forcing Chinese to fit technology[24:23]

Designing the Wubi method: decomposing characters into components

Concept of character components as 'atoms'

Wang observed that many Chinese characters share repeating components or shapes, so they are not all unique like 'snowflakes'[25:29]
He likened characters to molecules and recurring components to atoms in chemistry: many molecules but fewer atoms[25:02]
His idea was to identify a limited set of basic components and put those on a QWERTY keyboard so users could 'spell' characters by shape, not sound[25:29]

Illustrative example: the character for 'river' (Jiang)

The character Jiang looks like a capital 'I' with three dashes on the left; Wang breaks it into two components[25:39]
• The 'I'-shaped component is itself the character for 'work'; the three dashes represent 'water'
Work plus water visually combine to mean river, and the water component also appears in characters like 'juice', 'sweat', and 'soup'[26:09]

Five-year process of component analysis and reduction

Wang set up a nearly empty room with desks and small staff to analyze 10,000 characters[26:52]
They broke each character into components and wrote each component on its own note card, generating about 120,000 cards in total[27:14]
• If stacked, the cards would form a pile about 12 meters tall, roughly the height of a three-story building
Many cards were duplicates because the same component appeared in multiple characters, like the water component in 'river,' 'soup,' 'sweat,' and 'juice'[27:50]
Wang grouped identical components into piles, yielding several thousand distinct components, then repeated the process by further breaking and regrouping them[28:14]
After five years of iterative reduction, he arrived at 125 basic components, which he called a 'periodic table of Chinese'[28:47]

Mapping components to the QWERTY keyboard and naming Wubi

Wang arranged about five components on each QWERTY key, similar to how multiple letters share a number key on an old flip phone[29:05]
• Users would type the sequence of component codes for a character, and the computer would assemble and display the full character
He called the input system 'Wubi' and described it as a 'sacred invention'[29:38]

Wubi's public debut and political impact

Demonstration at the United Nations

In 1984, Wang was invited to the UN to demonstrate Wubi; he set up his computer in front of observers[29:29]
As he typed and Chinese characters rapidly appeared on the screen, a deputy secretary watching was astonished and suspected a trick[30:20]
Observers asked him to step away and flipped the keyboard, looking for hidden hardware; Wang told them it was just their standard keyboard[30:51]

Domestic fame and adoption of Wubi

After the UN demo, Wubi and Wang became hugely famous in China, with Wang named among the top ten biggest names in the country[31:04]
He licensed Wubi worldwide and appeared in infomercials and photos with important figures[29:36]
On China's National Day, he was chosen as head of ceremonies for Henan province, symbolizing his national prominence[31:24]

Meeting with Communist Party leader Hu Yaobang

On April 4, 1984, Communist Party head Hu Yaobang visited Wang to learn about his invention[31:54]
After hearing Wang's explanation, Hu asked whether Chinese characters still needed to be abandoned[32:26]
Wang replied that characters did not need to be replaced and could be efficiently input like English[32:27]
According to Wang, not long after, the State Commission on Language Reform was shut down, in part because Wubi had made characters compatible with computing[32:48]
Companies adopted Wubi, students were taught it, and learning Wubi became synonymous with learning to use a computer[33:08]
Wang saw himself as a singular inventor comparable to figures like Ford, Edison, or Steve Jobs[33:29]

Explosion of Chinese input methods and early predictive typing

Conceptual shift introduced by Wubi

Tom notes that Wubi subtly shifted typing from a direct 'what you type is what you get' model to one where keys represented abstract properties of characters[38:28]
After that shift, the letter on a key (like 'A') no longer had to correspond to the letter displayed; instead, 'A' could stand for any feature of a Chinese character, such as a component[38:27]
This opened a conceptual space where many different mappings between keys and character properties became possible[38:27]

Proliferation of competing input methods

Computer scientist Zhou Ming says that in the early 1980s, more than 1,000 input methods (IMEs) were developed and put into use[38:21]
Some methods matched components that visually resembled English letters to those letter keys (e.g., a mountain-peak-like component to 'A')[39:34]
Other systems used English letter initials based on meaning, such as using 'T' for the component 'tree'[40:45]
Another family of methods encoded only the shapes present in the four corners of each character[41:08]
Some systems abandoned letters and used only the numeric keypad, assigning each character a numeric code like 4303 for 'dog' or 9080 for 'fire'[41:25]
Competition among system creators became intense, with claims that each new method was easier and faster[40:34]
Zhou recounts that at one conference, a fight broke out over input methods and someone had to be removed[42:04]

Early predictive text and auto-completion in Chinese

Developers tried to increase speed by predicting what character a typist wanted before all component keystrokes were entered[41:52]
Systems would offer a small menu of candidate characters ranked by probability; typists selected the correct one with another keystroke[41:52]
Engineers soon extended this to predicting the next character or word, based on common sequences like 'Bei' being followed by 'Jing' or 'fang'[43:12]
Tom says that predictive text and auto-completion appeared in Chinese information technology decades before similar features became common in English computing[42:40]

Rise of pinyin-based input and its cultural implications

Government promotion of pinyin

Pinyin uses the Latin alphabet to spell out the sounds of Chinese characters and words, such as 'Beijing' for 'Bei' + 'Jing'[43:32]
In the 1980s, China began to prioritize teaching pinyin in schools, making it central to literacy education[44:48]
Tom explains that kindergartners often learn pinyin at the same time or even earlier than they learn to read and write Chinese characters[45:00]

Shift from shape-based to phonetic input

Computer scientists realized that since the education system was teaching a mapping from Latin letters to character sounds, it was logical to exploit that for typing[45:16]
They began designing input methods where users typed the pinyin spelling of words and then chose the intended characters from suggestions[44:32]
Wang strongly opposed pinyin-based input because he felt it severs the connection to character shape, which he considered the 'soul' of Chinese writing[44:42]
• He likened pinyin-only input to doing away with a person's flesh and said you cannot fully express a character's meaning through sound alone
He warned that as people rely on pinyin to type, their ability to write characters by hand declines[45:28]
Despite his objections, from the early 1990s Chinese input gradually shifted toward phonetic pinyin systems, displacing shape-based methods like Wubi[46:12]
Yang Yang notes that most people in a modern Chinese Starbucks are likely using some kind of pinyin editor, even though a variety of methods still exist[46:00]
Yang Yang personally admits that heavy pinyin use has caused her to forget how to write some characters by hand and that she cannot type using Wubi[46:23]

Typing competitions and Wubi's enduring speed advantage

Structure of Chinese typing competitions

China holds typing competitions at local and national levels, sometimes televised, where typists using different input methods compete[48:02]
Contestants publicly declare which input method they use, often representing or sponsored by the method's creators[49:13]
Some competitors use blank keyboards with no printed letters, showing their memorization of key mappings[49:28]
In each event, a previously unseen text appears on all screens, and the race begins when the clock starts[49:38]

Observed performance and Wubi victory

During the 2016 finals at an eSports hall in Beijing, cameras showed contestants typing extremely quickly while screens filled with Chinese text[48:26]
A given typist's screen showed sequences of Latin letters being entered, then a small box popping up with multiple character options, one of which was selected by keystroke[50:18]
The winning speed in that contest was 244 characters per minute, which Jad reacts to as extraordinarily fast compared with his father's 80 words per minute in English[50:51]
In that competition, the winner used Wubi, demonstrating that shape-based Wubi can still outperform phonetic systems in maximum speed[51:29]
Tom notes that Wubi-like methods often win high-level competitions and that their top speeds exceed what is possible with phonetic input[50:44]

Why pinyin dominates despite Wubi's speed

Tom attributes the dominance of phonetic input largely to Chinese state policy, which promotes phonetic systems for language unification[52:06]
Spoken 'Chinese' actually comprises many distinct languages (Cantonese, Shanghainese, Fujianese, etc.) that sound very different but share the same written characters[51:35]
Shape-based input like Wubi allows people to maintain their regional spoken language while typing, because they rely on character forms, not standard pronunciation[51:56]
Phonetic input forces users to learn and use standard Mandarin pronunciations, which aligns with government goals of linguistic unification[52:06]
Tom notes that the language-reform commission that Wubi's success had helped shut down later re-emerged and removed Wubi from school curricula[51:29]

The QWERTY effect: how keyboard layout shapes preferences

Definition and findings of the QWERTY effect

Researchers in the early 2000s found that English speakers tend to like words that have more letters typed with the right hand on a QWERTY keyboard than the left[55:19]
Right-side letters such as U, L, P, K, M, and J are associated with more positive feelings than left-side letters like Q, W, X, Z, and R[55:48]
The effect appears across multiple languages (English, Spanish, German, Dutch) and for both right- and left-handed people[55:42]

Arbitrariness of the QWERTY layout

The top row 'QWERTY' contains all the letters of the word 'typewriter', allegedly arranged that way so early salesmen could quickly type 'typewriter' during demos without knowing how to type properly[56:16]
This story suggests the keyboard layout's left-right distribution of letters was essentially arbitrary and not designed to shape emotional associations[56:50]

Evidence that keyboard layout reshapes behavior over time

Researchers analyzed U.S. Social Security baby-name data from the 1960s to 2012, designating 1990 as the year QWERTY became ubiquitous[57:18]
They found that after 1990, there was an increase in names containing more right-hand letters than left-hand letters, consistent with the QWERTY effect[57:26]
Examples discussed include names like Paul or Leah; Simon notes his own name has four right-hand letters and one left, while Jad's has one right-hand and two left-hand letters[57:26]
Jad relates this to a philosophical idea (attributed vaguely to German philosophers) that tools like a hammer do not merely extend the hand but also reshape it[58:00]
They conclude that the QWERTY keyboard, an arguably outdated and arbitrary standard, is now influencing preferences in areas as intimate as naming children[58:15]

Attempt to study QWERTY effect in China

Simon says graduate students tried to study an analogous effect in China but methodological difficulties arose because there are so many different input methods[58:54]

Cloud-based AI input in China and its implications

From local prediction to cloud-based suggestions

Tom describes a new phase of 'cloud input' where typing systems use artificial intelligence and aggregate data from many users[59:22]
He compares it to Google's search bar, which suggests completions based on what is trending and what others are searching for, rather than just static frequency[59:44]
In China, this cloud-based influence extends beyond search into everyday text entry in programs like Microsoft Word[59:52]
Example: if a disgraced pop star's name becomes widely typed, the system can infer that a local user beginning to type that name likely wants that suggestion, even if they have never typed it before[1:00:02]
Tom emphasizes that such systems mean every keystroke and word is in some sense influenced by what millions of other users are typing at the same time[1:00:36]

China's leapfrog in typing speed and technology

Tom argues that over the last two decades, Chinese has become arguably the fastest language to type in the computational realm, owing to advanced input systems[1:00:53]
Simon and Jad note that the West now looks to China, trying to figure out how to catch up in this area, describing it as a 'crazy leapfrog' over about 40 years[1:01:22]

Concerns about AI co-authoring and agenda

Tom calls the situation both invigorating and eerie, describing it as 'post-futuristic' and expressing concern about speed of suggestion overtaking speed of thought[1:01:47]
He imagines scenarios where the system suggests actions or phrases before the user consciously intends them, and the user accepts them as good ideas[1:02:00]
He frames this as moving into 'co-writing,' where the system acts like a writing partner giving suggestions, but one that simultaneously partners with thousands of others[1:02:16]
Tom calls this a 'pretty terrifying scenario,' and Jad adds that such a writing partner likely has an agenda, or at least is shaped by one[1:02:36]

Outro and credits

Closing reflections

Jad says he now regards his own QWERTY keyboard with suspicion after hearing how it and input systems can shape behavior and thought[1:02:58]

Production credits

The story was reported and produced by Simon Adler with reporting assistance from Yang Yang and original music by Simon[1:03:18]
Special thanks are given to Yang Yang and to historian Tom Mullaney for his years of research guiding the story[1:03:33]
They also thank Daniel Casasanto for explaining the QWERTY effect and list Radiolab staff and fact-checkers[1:03:49]

Lessons Learned

Actionable insights and wisdom you can apply to your business, career, and personal life.

1

Technological systems and standards quietly embed the assumptions and needs of the cultures that create them, and if you adopt them uncritically, they can marginalize or erase your own ways of working and thinking.

Reflection Questions:

  • • Where am I currently relying on tools or platforms that were designed for a context very different from my own, and how might that be constraining me?
  • • How could you more deliberately adapt or configure the tools you use so they better reflect your language, values, and workflows instead of the default settings?
  • • What is one domain in your work or life this week where you could question an inherited standard and explore an alternative that fits you better?
2

Persistence in decomposing complex problems into smaller, reusable components can turn an apparently impossible challenge into a solvable engineering and conceptual task.

Reflection Questions:

  • • What current problem in your life or business feels 'too big' mostly because you haven't yet broken it down into its fundamental parts?
  • • How might you imitate Wang's approach of iteratively simplifying and regrouping components over months or years instead of expecting a quick solution?
  • • What specific project could you revisit this week to list out its 'atoms'-the smallest repeatable elements you can recombine in new ways?
3

Design choices that optimize for speed and convenience-like phonetic input or predictive text-often carry long-term tradeoffs in skills, diversity, and cultural preservation.

Reflection Questions:

  • • Where in your routines have you chosen the fastest or easiest option without examining what skills or richness you might be losing?
  • • How could you deliberately preserve or practice an older or more demanding skill (like handwriting, deep reading, or mental math) that matters to you despite new shortcuts?
  • • What is one convenience feature you use regularly that you could turn off temporarily to see how it changes your awareness and capability?
4

When many people share the same intelligent tools, those tools don't just reflect collective behavior-they can start to steer it by nudging everyone toward similar patterns of language and thought.

Reflection Questions:

  • • What phrases, ideas, or decisions in your recent writing or communication might have been shaped by autocomplete, templates, or popular suggestions rather than your own voice?
  • • How could you create a buffer-such as drafting offline or pausing before accepting suggestions-to ensure your intent leads and the tool follows?
  • • In which area of your work or creativity would it be most valuable this month to resist homogenizing influences and consciously cultivate a distinctive style or perspective?
5

Tools that feel neutral or 'just hardware'-like a keyboard layout-can exert subtle, measurable influence on preferences and decisions over time.

Reflection Questions:

  • • Which everyday interfaces (keyboards, apps, feeds, forms) are you so used to that you rarely question how they might be shaping your choices?
  • • How might you run a small experiment-changing a layout, input method, or default setting-to observe how your behavior and preferences shift?
  • • What is one important decision you're facing where you could step away from your usual tools and environment to see whether you choose differently?
6

Top-down policy and incentives can determine which technologies win adoption, even when alternative designs are objectively better on some metrics like speed or efficiency.

Reflection Questions:

  • • Where in your organization or industry do you see a 'better' technical solution losing out because of policy, training, or institutional inertia?
  • • How could you align your preferred solutions with existing incentives or decision-makers' goals so they have a better chance of being adopted?
  • • What is one concrete step you could take this quarter to influence standards or guidelines in your domain rather than just adapting to them?
