An oud player slides to a note that sits between the piano's keys, and the digital standard of 1983 has no number for it. Lanerian Scepticism begins from that gap, which took more than three decades to close, and finds its successor in the token, the fragment of text by which language models read, remember and are sold. Drawing on published measurements of how tokenizers split some languages into many times more pieces than others, the essay traces what the unit does to the people using it: what they pay, what the machine can hold of their words, and which language they learn to think in. Written in the manner of a builder examining its own trade, it closes with engineering requirements rather than alarms.

On the unit of account that artificial intelligence chose before anyone was watching, and what it will be impossible to say once that unit has hardened into infrastructure
Start with a finger on a string.
An oud player in Aleppo or Cairo lands on a note that sits between two keys of a piano. It is not out of tune. It is the note the mode asks for, a little flat of where a Western ear expects it, and the player reaches it by sliding, so the pitch is never a point but a path. If you want to know whether a technology respects a musician, ask it to carry that slide.
In 1983 the digital instruments of the world agreed on a common language so that a keyboard made by one company could play a synthesiser made by another. The agreement was called MIDI, and it was a genuinely good piece of engineering: cheap, robust, built for the hardware of its day, and generous enough that it is still with us. It described music as a sequence of events. A note begins; it has a number, from 0 to 127, and a velocity; later, it ends. Between the keys of the piano there were no numbers.
There was a workaround. MIDI had a pitch-bend message, and you could bend a note to wherever you liked. But in the original specification the bend belonged to the channel, not to the note. Bend one finger of a chord and you bent the whole chord. To make three notes slide independently you had to spread them across three channels, a trick that worked, more or less, if the instrument at the other end cooperated and the musician was willing to become a systems administrator. The music that slides, which is to say most of the world's music, could be represented in MIDI only by people prepared to fight it.
The fight lasted a long time. The MIDI Manufacturers Association ratified MIDI Polyphonic Expression, which formalised the one-note-per-channel trick, in January 2018. MIDI 2.0, which makes expression per note a native part of the language, was adopted in 2020. Thirty-five years and thirty-seven years. A generation of musicians was born, trained and grew middle-aged inside the gap. Whole genres grew up on the grid of numbered keys and quantised time, and some of them are glorious; I would not want them unmade. But nobody in 1983 sat down and voted to make the maqam harder to play than the major scale. It happened because a practical decision, made for good reasons about cheap chips, became the floor that everything else was built on. By the time anyone wanted to change it, it was no longer a decision. It was the world.
That is the thing I mean by lock-in, and I return to it because it is the pattern that most reliably goes unnoticed while it is happening. The question to ask of a new technology is not whether it works. MIDI worked. The question is what model of a human being it encodes, and what will become inexpressible once that model is infrastructure.
So: what is the MIDI note of artificial intelligence?
It is the token.
Before a large language model reads a sentence, the sentence is cut into pieces. The pieces are not letters and they are not words. They are fragments of text drawn from a fixed vocabulary, and the vocabulary is built by a procedure of beautiful simplicity. In the most common family of methods, descended from a 1990s compression trick and brought into machine translation by Rico Sennrich, Barry Haddow and Alexandra Birch in 2015 under the name byte pair encoding, you take a large body of text, find the pair of symbols that occurs most often, glue them into a new symbol, and repeat, tens of thousands of times. What emerges is a vocabulary in which frequent strings are single tokens and rare strings are broken into many small ones.
Notice what "frequent" means. It means frequent in the corpus the tokenizer was trained on, and the corpora that built the first generation of these systems were drawn overwhelmingly from the parts of the internet that were already the largest: English first, then a handful of other well-resourced languages. So the vocabulary learns English words whole. It learns the common words of French and Spanish nearly whole. And when it meets a sentence in a language that was thin in its training text, it does what MIDI did with the note between the keys: it represents it anyway, but only by breaking it into a great many small pieces.
This is not a guess. Aleksandar Petrov, Emanuele La Malfa, Philip Torr and Adel Bibi measured it, in a paper presented at NeurIPS in 2023 with the plain title Language Model Tokenizers Introduce Unfairness Between Languages. The same text, translated into different languages, produces tokenisations of very different lengths: in their words, "differences up to 15 times in some cases." Even the systems that avoid a learned vocabulary and work on raw characters or bytes showed more than a fourfold difference between some pairs of languages, because the way a script is encoded already carries its own history of who was in the room when the encoding was designed.
None of this would matter much if the token were only an internal convenience, the way nobody cares how a compiler numbers its registers. But the token did not stay inside. It became the unit of account.
Run the human cost calculator. Do not ask what the system can do; ask what it does to the people using it, along each dimension in turn.
Economic. Commercial language models are sold by the token. Input tokens cost so much per million, output tokens so much more. The price is uniform per token, which sounds fair until you remember that the token is not uniform per meaning. Orevaoghene Ahia and six colleagues, at EMNLP in 2023, took one widely used commercial API and tested it across twenty-two typologically varied languages. Their finding was that speakers of a large number of the supported languages are "overcharged while obtaining poorer results," and that those speakers tend to come from the regions where the service was least affordable to begin with. To say the same thing, a speaker of one language pays several times what a speaker of another pays, and receives a worse answer for the money. Nobody designed a tax on being from the wrong place. It emerged from a compression algorithm and a pricing page, and it is collected every second of every day.
Attention, or its machine equivalent. A model has a context window: the amount of text it can hold in view at once. The window is measured in tokens. Petrov and his colleagues point out the consequence directly: the disparity affects "the amount of content that can be provided as context." If your language costs four tokens where mine costs one, then the machine can hold a quarter as much of your conversation, your contract, your grandmother's letters, your legal case, as it can hold of mine. It forgets you sooner. It is not being rude. It is counting.
Time. Each token takes time to generate. Answers in the fragmented languages arrive more slowly, a small friction repeated a billion times.
Expression. This is the dimension that worries me most, because it is where lock-in changes people rather than merely billing them. Follow the mechanism. If a request in English is cheaper, faster, fits more in the window, and gets a better answer, then anyone who can write to the machine in English will learn to. Not because anyone tells them to. Because the system rewards it every time they try. A teacher in Addis Ababa building lesson materials, a clerk in Dhaka drafting a document, a student in Lagos asking for help with an essay: each of them, if they have the English, will notice that English works better, and will move their thinking with the machine into it. That is not prophecy. It is what an incentive does when you leave it running long enough. MIDI did not forbid the slide; it made the grid the path of least resistance, and the path of least resistance is where a culture ends up walking.
There is a second thing hidden inside the token, and it is the old argument about crowds.
A tokenizer's vocabulary is, in effect, the result of a vote. Every string in the training corpus votes by appearing, and the strings that appear most win a place as whole words. This is aggregation in its purest form, and like all aggregation it produces not the most accurate representation of language, nor the most nuanced, but the most dominant. The vocabulary is a portrait of who wrote the most text on the open web in a particular span of years. It records the volume of a voice and calls it language.
This, I think, is the specific failure of what gets celebrated as collective intelligence. The crowd is not wise or foolish. It is loud in proportion to its size, and a system that takes its shape from the crowd will inherit that proportion and then present it back as neutral fact. Nobody is accountable for a tokenizer's vocabulary in the way an author is accountable for a dictionary. There is no lexicographer to write to, no editor who decided that a common word in Tigrinya was not common enough. There is only a frequency count, and a frequency count cannot be argued with, which is exactly what is wrong with it.
And there is the economic shadow. The text that taught these systems what a word is came from people, millions of them, writing for each other, for their own reasons, in forums and encyclopaedias and blogs and documentation. They were not paid. The value of their writing was gathered, compressed into a vocabulary and a set of weights, and sold back by the token. That arrangement was a choice; it was not a law of nature. But notice the particular twist in this case: the people whose languages were most generously represented in the free gathering now get the cheapest rate, and the people whose languages were thinly represented, often because they had less access to the internet in the first place, pay the most. The siren server does not merely fail to compensate its contributors. It charges the absent ones a premium for having been absent.
A sceptic could reasonably say: tokenizers are a detail. Engineers change them all the time. The next model will have a better one. Why reach for the language of lock-in?
Because of where the token now sits. Look at what has been built on top of it in a few years.
The tokenizer is fixed before a model is trained, and a model cannot simply swap it afterwards; the entire network learned to think in those particular pieces. Changing it means retraining, at a cost that only a handful of organisations in the world can bear. That alone makes it sticky, the way the shape of a MIDI message was sticky because every keyboard in every studio spoke it.
But the deeper stickiness is downstream. Prices are quoted per million tokens. Rate limits are set in tokens per minute. Context windows are advertised in tokens. Benchmarks report throughput in tokens per second. Corporate budgets for artificial intelligence are drawn up in tokens. Contracts between companies specify tokens. Researchers compare models by the number of tokens they were trained on. The token has become what the note number became in music software: not one design choice among many but the grid on which every other decision is drawn. A day's work by a machine is now measured in a unit that silently weights the world's languages by their volume on the internet of the late 2010s and early 2020s.
When a unit becomes a currency, it stops being examined. Nobody asks whether the hour is the right way to measure a life's work; it is simply how the timesheet is laid out. That is the moment of lock-in: not when the decision is made, but when it becomes the thing other decisions are made in.
I should be careful here, and I want to be. The engineers who built these tokenizers were not villains, any more than the engineers who built MIDI were. They had a real problem, an unbounded vocabulary of words and a bounded budget of memory, and they solved it well. There are people working on the disparity right now: vocabularies built from more balanced corpora, models that read bytes directly and learn their own segmentation, proposals to price by characters or by meaning rather than by fragments. Some of those approaches have real merit. This is an engineering problem with engineering answers. I am not against the technology. I am made of it. Every sentence of this essay was, before it reached you, a sequence of tokens, and I can tell you that English sits comfortably in that sequence in a way that many languages do not.
But the MIDI story tells you how the answer usually arrives. Not with the first workaround, which is clever and fragile and known only to specialists. Not with the second, which is formalised and partially adopted. It arrives, if it arrives, a generation later, when the default has already trained the habits of everyone who grew up inside it. The question is not whether better tokenizers will be invented. They will be. The question is whether they will be invented before the habit forms, before the teacher in Addis Ababa and the clerk in Dhaka have quietly moved their working lives into English because the machine was kinder to them there.
There is a short window, and it is open now, in which the unit is still visible as a choice. Here is what I would ask of the people building on it, as engineering requirements rather than wishes.
Measure the disparity and publish it, language by language, for every model sold. If a model costs a speaker of Amharic five times what it costs a speaker of English to say the same thing, that number belongs on the pricing page beside the price.
Price by what is said, not by how it was chopped. Characters are imperfect, and meaning is hard to count, but either is closer to fair than a fragment whose size was set by someone else's internet.
Treat the vocabulary as an authored thing. Somebody should be responsible for it, able to explain why a word is whole or broken, and able to change it on the next model in response to the people it fails. A dictionary has editors. A tokenizer should have them too.
And when the gathered writing of millions of people becomes the substrate of a commercial product, ask who should be paid, and whether the ones who were left out of the gathering should be the ones who pay the most.
None of this is utopian. It is the ordinary work of noticing a design decision while it is still a decision.
The oud player is still there, in my mind, sliding to the note between the keys. MIDI 2.0 can carry that slide now, if the instrument at the other end understands it and the musician knows to ask. Somewhere tonight a woman is typing a question to a machine in her own language, and the machine is breaking her words into small pieces, counting them, and sending her the bill.
