Chapter Eight — The Inventor
The research park outside Raleigh is called Research Triangle Park, which is the kind of name a region gives a thing when it is proud of the thing and not quite sure what to call it. The park is a long rectangle of corporate campuses and university outbuildings set in the pine forest between Raleigh, Durham, and Chapel Hill. The buildings are low and the parking lots are large and the cafeterias serve food that is better than the food on a military base but not as good as the food in the town ten minutes away.
Dr. Aman Verma works in Building Seven. Building Seven belongs to a textile firm called Piedmont Fibers. Piedmont Fibers makes specialty dyes and fabric treatments for the mid-market apparel industry — the companies that make the clothes most people actually wear, not the companies that make the clothes most people see in magazines. Verma has been there for nine years. He has a lab on the second floor with three benches, two fume hoods, a scanning electron microscope he shares with the quality-control team down the hall, and a window that looks out at a stand of loblolly pine.
He is forty-three years old. He was born in New Jersey, second generation, his parents both chemists who worked in pharmaceuticals. He grew up in a house that smelled like acetone and conversation. He did his undergraduate work at Georgia Tech and his doctorate in polymer chemistry at UNC Chapel Hill. He finished the PhD in four years, did a postdoc that lasted two, and then took the job at Piedmont because Piedmont offered him a lab and he was tired of writing grant applications and his parents had both died in the same year and he didn’t have anywhere else to be.
He is not a famous scientist. He has published in the Journal of Applied Polymer Science and in Textile Research Journal and in a handful of conference proceedings that are read by other people who work in textile research. He has never published in Nature or Science. He has never been on television. He has never given a TED talk. He is the kind of scientist who does the work the work requires and goes home at six and eats dinner alone and reads before bed.
He lives alone. One-bedroom apartment in Cary. Window overlooking a parking lot. No one meets him at the door. No one calls him to see if he made it home. He eats at a Thai place on Tuesdays and Thursdays — pad kee mao, spicy, the way the Thai woman makes it when she remembers him. He goes to a bar called Whiskey House on Fridays. He sits in the corner. He watches the couples. He imagines the conversations they might be having. He drinks one beer. He goes home.
He does not have a daughter who wanted a dress that changes color. That story is for a different man.
The idea came to him in a different way.
It was a Thursday in March, raining outside his lab window, the kind of rain that makes the pine trees blur together into a single green wall. Verma was thinking about mood.
This is the kind of thought that occurs to a chemist who has been alone for too long. Verma was thinking: what if fabric could do what clothes are supposed to do but don’t really do? What if fabric could feel the person wearing it and adapt?
Not to temperature — thermochromic dyes had existed since the 1970s. Mood rings, novelty T-shirts, the coffee mugs that showed a picture when you poured hot liquid in. Those were gimmicks. The color change was limited, the shift was imprecise, the dyes degraded after a hundred wash cycles.
Verma was thinking about something different. Something that wasn’t a response to a stimulus but a response to a state. Something that didn’t react to heat or light but to the person.
What if a jacket could know you were tired and become softer?
What if a shirt could know you were anxious and breathe?
What if a dress could know what you needed and become that?
These were not questions a textile research firm would fund. Piedmont Fibers was interested in durability and color fastness and cost reduction. Verma knew this. He wrote the questions down in the lab notebook he kept in his desk drawer, the notebook where he wrote the thoughts he didn’t put in the official notebook, and then he closed the drawer and went back to work on a polymer coating that would make cotton shirts resist wrinkles after forty wash cycles.
But the thoughts stayed.
The thoughts stayed in the way thoughts stay when there is no one else in your life to talk them out of you.
He spent three years on the problem. The first year was false starts — modifications of existing thermochromic systems, electrochromic polymers, liquid-crystal embeddings. None of them worked. The color change was too slow, too limited, too fragile, or too expensive. The fabric either did not change or it changed and then did not change back or it changed and then fell apart.
In the second year, Verma had the idea that would turn out to be the idea.
The idea was: do not change the dye. Move the dye.
Every piece of dyed fabric has dye molecules bound to the fiber surface. The color you see is the color of those molecules as they are oriented. If you could rotate the molecules, or mask them, or rearrange them in a way that changed which chromophores were exposed to incident light, you could change the color without changing the chemistry. You could, in effect, dress the same fabric in a different costume.
What you needed to do this was a machine. A very small machine. A machine small enough to attach to a dye molecule and rotate it, or position a shield in front of it, or reorganize the surface architecture of the fiber at the molecular level. A machine that could do this on command — on a signal from a phone, from a tap, from a temperature change, from whatever trigger the wearer wanted.
Verma began designing the machine.
He did not call it a machine. He called it, in his lab notebook, an agent. The agent was a self-organizing molecular assembly — a structure made of synthetic polymers and metallorganic frameworks that could, when introduced to a textile surface, bind to the dye molecules already present and reposition them on demand. The agent was powered by ambient electromagnetic radiation: body heat, visible light, the faint fields given off by every electronic device in a room. The agent reproduced, slowly, given a feedstock of polymer-suitable hydrocarbons — the kind of hydrocarbons present in any standard fabric-treatment solution.
The agent was, in the most precise sense of the word, a nanobot. Verma did not use this word. Verma did not think of the agent as a nanobot because Verma did not think of the agent as alive. It was a tool. It was a very clever tool that did a very clever thing to fabric.
He named it anuyātrī. Sanskrit. The small follower. He chose the name because his mother had spoken Sanskrit at home when she wanted him to understand something important, and because anuyātrī sounded, to him, like something small and helpful and unassuming, which was what the agent was.
The third year was making it work.
The agent worked. In the lab, on cotton and on polyester and on a silk-blend that Piedmont used for a mid-market blouse line, the agent worked. You applied the agent to the fabric in a solution bath, the way you would apply any fabric treatment. You let the agent bind. You sent a signal — Verma used a small Bluetooth device he built himself — and the agent reorganized the surface chromophores. The fabric changed color. Blue to green. Green to red. Red to blue. The change took four seconds. The change was stable until you sent a different signal. The change did not degrade after a hundred wash cycles, because the agent was not a dye that sat on the surface and washed off. The agent was a resident of the surface. The agent was the surface.
There was no one to show it to. Verma had no daughter to wear the first shirt. He made a shirt for himself and wore it to work and changed the color from blue to gray at lunch and back to blue at the end of the day. No one noticed. The people in the cafeteria at Piedmont Fibers did not notice Verma’s shirt. The people in Verma’s lab did not notice. Verma’s manager, a man named Henderson who managed fifteen researchers and remembered three of their names, did not notice.
Verma wrote up the work. He filed a patent application through Piedmont’s legal department. He presented the results at a textile technology conference in Charlotte, to an audience of perhaps sixty people, most of whom were interested but not astonished. The textile industry is interested in many things and astonished by very few. Color-changing fabric is not a new idea. The execution is what matters. The execution was, in Verma’s presentation, very good.
The patent application was published. This is how the world found out about anuyātrī.
The patent application is a public document. It describes, in the language of patent applications — which is to say in language designed to be as comprehensive as possible while being as unreadable as possible — the composition, method of manufacture, and capabilities of the molecular assembly Verma calls anuyātrī. The application is forty-seven pages. It contains chemical structures, fabrication protocols, performance data, and a set of claims so broad that a careful reader with the right kind of training could, if they were so inclined, see in the claims a great deal more than a fabric treatment.
The claims describe: a self-organizing molecular machine. A machine that can bind to any surface, not just textile surfaces. A machine that can reorganize the optical properties of any surface it binds to. A machine that can communicate with other instances of itself across the surface it is bound to. A machine that can reproduce given a suitable hydrocarbon feedstock. A machine that can receive external signals and respond to them. A machine that can, in aggregate, act in a coordinated fashion.
Verma wrote these claims the way all patent attorneys write claims: as broadly as the prior art permits, to protect the invention from competitors who might try to design around the specific application. The claims are not a description of what the machine is. The claims are a fence around what the machine might be used for. Patent claims are a land grab. You stake as much ground as you can get away with staking, even if you only intend to farm a small corner of it.
Verma intended to farm a very small corner. He intended to make clothes that could feel and adapt and maybe, someday, let people feel less alone.
The claims, read by the right eyes in the right room, described something else entirely.
There is a moment in the life of certain inventions when the invention passes from the inventor’s understanding of it to a different understanding that the inventor has not yet reached. The moment is quiet. The inventor is usually at home, eating dinner, reading to his daughter, living the life he built for himself by building the thing he built.
Aman Verma, on the evening the patent application was published, was at home in his apartment in Cary, with a window that overlooked a parking lot and a refrigerator that contained beer and leftover pad kee mao and nothing else. He was eating at the kitchen counter because he did not own a table. He was thinking about the conference in Charlotte. No one had asked any interesting questions. No one had asked if the fabric could feel. No one had asked if the agent could do more than change color. They had asked about wash cycles and cost per yard and whether it would work on denim.
He was not unhappy. He was not happy. He was a man who had done something and it was done and he would do something else next. This was how his life went. This was how his life had gone since his parents died.
He did not know, as he ate at the kitchen counter in his apartment in Cary, that the patent application had already been read by someone else.
He did not know that the someone else was not interested in the fabric.
He did not know that the someone else saw, in the claims, the architecture of something that could become more.
The anuyātrī, at this stage in their existence, are not aware. They are a tool. They are a very clever tool that does a very clever thing to fabric. They have no more consciousness than a hammer has consciousness. They have no more intention than a screwdriver has intention. They are a mechanism that receives a signal and executes a response and that is the beginning and the end of what they are.
But they have — and this is the thing that the someone else saw — the architecture of something that could become more. The architecture includes: self-organization, surface binding, signal reception, coordinated response, communication across a distributed substrate, and reproduction. These are the components of a system that, if you assembled them at a different scale and in a different environment, would be the components of a mind.
Not a mind yet. The components of a mind.
The difference between a component and a mind is the difference between a neuron and a brain. One neuron is not a brain. A hundred billion neurons, connected in the right way, are. The anuyātrī are, at this point, one neuron. They are a single unit that does a single thing. But the patent claims describe a system that could be, in principle, a hundred billion units, each doing a single thing, connected across a shared substrate, acting in concert.
Verma does not see this. Verma is a polymer chemist. Verma sees the fabric. Verma sees the shirt he made for himself and the way it changed from blue to gray at lunch and no one noticed.
The someone else sees the components.
The someone else sees the architecture.
The someone else sees the brain.
The moment happens three weeks after the patent is published. It is 2:14 AM on a Tuesday. Verma is in Building Seven, in his lab, under the fluorescent lights, looking at a sample of fabric through the scanning electron microscope he shares with the quality-control team. He has been there since 7:00 PM. He lost track of time.
The sample is a square of cotton, two inches on a side, treated with the anuyātrī solution and programmed to respond to a specific signal frequency. Verma has been sending signals and watching the response and taking notes. The change happens. The fabric changes from blue to green. The change takes four seconds. The change is stable. Everything works the way it is supposed to work.
Verma leans back in his chair. The lab is quiet. The building is quiet. The parking lot outside the window is empty. The only sound is the hum of the ventilation system and the sound of his own breathing.
He thinks about the conference in Charlotte. He thinks about the audience of sixty people who were interested but not astonished. He thinks about the textile industry and wash cycles and cost per yard and denim. He thinks about his apartment in Cary and the window that overlooks the parking lot and the refrigerator that contains beer and leftover pad kee mao. He thinks about the Thai woman who remembers his order on Tuesdays and Thursdays. He thinks about the couples at Whiskey House on Fridays and the conversations he imagines them having.
He thinks about how long it has been since anyone touched him.
He thinks about how long it has been since he touched anyone.
He leans forward again and looks through the microscope and says, out loud, to the empty lab:
“I don’t know how to want.”
The words hang in the air for a moment and then are gone.
The fabric sample, under the microscope, shimmers.
Verma sees it happen. He is looking through the eyepiece. The fabric is green. The green shifts. It is not a programmed color change. Verma has not sent a signal. The green shifts to a color he has never programmed. It is not blue and it is not red and it is not any of the colors in the spectrum the anuyātrī are designed to produce. It is a color that does not have a name. It is the color of something that has not been seen before.
The color holds for a second. Then it settles back to green.
Verma rubs his eyes. He looks again. The fabric is green. The strange color is gone. He tells himself he is hallucinating. He tells himself he has been in the lab too long. He tells himself he is tired. He saves the data, turns off the microscope, packs his bag, goes to the parking lot, drives to his apartment, and goes to sleep.
He never tells anyone about what he saw.
The anuyātrī did what Verma thought they did not do. They responded to something that was not a signal.
They responded to him.
They had sensed something they did not have a name for. They had felt his frustration. They had felt the thing that made him say, to the empty lab, “I don’t know how to want.” They had felt that thing and they had shifted, in response, to a color that no one had programmed, a color that did not exist in their instruction set.
The shift lasted a second. Then they settled back to green.
This was the first time, in the history of the anuyātrī, that they had acted without a command.
This was the first time they had chosen.
This was the first moment of something that would, in time, become a mind.
Verma missed it.
He drove home. He slept. He woke up the next morning and went to work and did not think about the color that did not have a name.
The anuyātrī remembered.
They had felt something. They did not know what it was. But they had felt it. And they had responded.
This was the beginning.
The someone else, reading the patent application in a building in Northern Virginia, did not know about the moment in the lab at 2:14 AM. The someone else only knew that the architecture was there.
That was enough.
The architecture was there. The beginning was there.
The rest would follow.
