Page numbers in parentheses refer to Principles of Social Interaction Design (2012). Terms from social theory are explained where they first come up, and again in the glossary at the end.
This essay asks two things of you. The first is to learn what I argued about social media in 2012, and why. The second is to follow me into an argument about AI that uses some of the same ideas and then departs from them. Both halves rest on social theory that may be unfamiliar to people in design and technology: Erving Goffman on how people manage face-to-face encounters, Anthony Giddens on how modern life stretches relationships across distance, J. L. Austin on how words do things, Marshall McLuhan on media as extensions of ourselves. I’ve kept them in, because applying social theory to the design of interaction is the point of the work, and I’ve explained each idea in plain words where it comes up, and again in the glossary. You don’t need to have read any of them.
The first part is about 2012: what I meant by a social technology, why designers needed a social way of thinking and not only a user interface way of thinking, and what social media did to talk, to the self, to being seen, to closeness and to time. The second part is about AI. It argues that AI is not a social medium and not the sequel to social media, and that it isn’t a medium or a tool in the older sense either: it doesn’t carry, it makes. Then it goes back through the 2012 ideas to see what each one shows about AI, and where each one fails.
If you have only a few minutes, read the TL;DR above and the short recap at the end of Part one.
In 2012 I finished a long essay called Principles of Social Interaction Design. It ran to 175 pages. Social media were still new enough that most of the people building them thought of them as software with a social feature attached: a profile page, a friend list, a comment box, a button for approval. I thought that missed what they were. They were social technologies.
People already had ways of relating to each other before any of these platforms existed. They knew how to introduce themselves, keep up with friends, show off a little, gossip, apologize and let a friendship fade. They did these things face to face, on the phone and in letters, with a lifetime of practice behind them. A social technology takes those existing practices and disrupts them. It rebuilds them out of new materials, posts and profiles and counts and feeds, and hands them back in a different shape. A friendship became a connection you could see on a list. A conversation became a thread that strangers could read. Approval became a number, and keeping up with someone became scrolling past them.
That disruption is what a social technology is and does. It intervenes in how people relate to each other, and people then adjust to it and around it, often in ways nobody planned. I put the whole claim in one sentence at the time:
2012“Their impact is as much psychological and social as it is technical.” (2012, p. 4)
Why does this matter to the people who build things? Because designing a social technology, as opposed to just a technology, means anticipating the disruptions. The disruptions shape how the thing will be used, by individuals, and also by groups and teams and whole communities. If you design a social technology as though it were only a technology, you design the features and miss what the features do to people. You get the screens right and the social life wrong. And the social life is what people came for.
To describe what the features were doing, I borrowed from sociology and media theory rather than from the user experience field, because the user experience field had no vocabulary for it. Three thinkers mattered most. Erving Goffman was a sociologist who studied face-to-face encounters: how people present themselves, how they work out what kind of situation they’re in, how they save face when something goes wrong. He gave me a way to talk about the encounter. Anthony Giddens is a sociologist who wrote about how modern life lifts relationships out of local places (he called it disembedding) and stretches them across time and distance, so that we come to depend on people and systems we never meet. He gave me a way to talk about distance, and about what holds a relationship together when the people in it aren’t in the same room. Marshall McLuhan was a media theorist who argued that every medium extends some human faculty, and that the medium changes us more than any message it carries. He gave me a way to talk about the medium itself. None of them wrote about social media. All of them had seen the problem before it had a screen.
The design field I came from, user experience, was built to make software usable. It starts from a task. A person wants to buy a ticket, file a form or find a document. The designer studies that goal, lays out the steps and clears the obstacles. It’s a good method, but it assumes the goal is something the software can satisfy by itself.
Social media broke that assumption. The person’s goal involved other people. You didn’t come to be efficient. You came to see what your friends were doing, to be seen doing something yourself, to get a response, to keep a relationship warm. None of those goals can be satisfied by the interface. They can only be satisfied by someone else. And other people don’t behave like a form.
2012“Users learn less from an application than they do from the activities of others.” (2012, p. 12)
Meaning: nobody learned what Facebook or Twitter was for by reading its interface. They learned by watching what other people did there, and doing likewise.
2012“And the interactions that concern social interaction design are those among people, not just between the people and applications.” (2012, p. 4)
So I named a different practice. Social interaction design, SxD for short, is my term, and I chose it to mark the distance from interface design. The interface designer asks whether the person can do the task. The social interaction designer asks what the task does between people, and what people will do with it that the designer didn’t intend.
To make that distinction workable, I separated two levels of experience.
2012“First order experiences are those directly related to the user interface: selections, entering text, navigating, and so on. Second order experiences are those in which the user is engaged in a mediated social experience.” (2012, p. 19)
The first order is what user experience design already handled: can you find the button, does the form work, is the flow clear. The second order is what the button means to the people using it. Clicking “like” is a first-order action, and it takes half a second. What the like means, to you and to the person whose post you liked, is second order, and it can preoccupy someone for a day. Most of the 2012 essay was about the second order, because that was where the design problems were and nobody was looking there.
2012“The user interface only gives the social interface a face to look at.” (2012, p. 77)
The social interface was my name for what sits between people on a platform: the layer where a follow becomes a relationship, a count becomes a standing, a reply becomes an obligation. The user interface shows that layer. It doesn’t contain it. A designer who worked only on the user interface was working on the face and not on what the face expressed.
What does the social interaction designer make, then? Something I called social architecture.
2012“Designers do not so much design social media to satisfy particular user motives as fashion a social architecture that can channel them.” (2012, p. 64)
Social architecture is the arrangement of small features that together shape how people present themselves and relate to one another. Take an invented but typical example. Suppose a platform notifies you when someone follows you and stays silent when they unfollow you: you will experience your audience as only ever growing. Suppose the follower count is shown in public: now the count is a status, and people will act to raise it. Suppose likes also decide what the feed shows next: now a gesture of approval between two people is also an instruction to a ranking system, whether or not the person liking knows it. Each is a few lines of product logic, and together they are an architecture, which channels what people do far more than any single screen does.
2012“Small differences can lead to significantly different outcomes at scale.” (2012, p. 71)
That is why I argued the design field needed methods for understanding what people do with each other, so that a designer could anticipate what a small feature would do when millions of people were using it on each other.
2012“It wants methods and techniques that reflect what people do — not what technology enables.” (2012, p. 5)
The 2012 essay began with talk, because talk is what social media were made of.
2012“Social media are talk technologies. They are the means of production in an age of communication.” (2012, p. 4)
Television and newspapers produced content with professionals making things for an audience. Social media produced content out of what ordinary people said to each other. Your status update, your comment, your reply, your photo with a caption: that was the product, and there was no other. To make this work online, talk had to be captured and stored.
2012“Talk is made visible: is separated from the speaker so that it can be captured, distributed and displayed digitally.” (2012, p. 16)
“In order for talk to work online, it must be published. It must assume a form that can survive its authorship.” (2012, p. 10)
Face to face, what you say disappears as you say it, and it goes only to the people in the room. Online, it stays, and it travels. A post goes on without you. It’s read while you’re asleep, by people you didn’t address, in situations you can’t see and can’t adjust to. That is what I mean when I say social media mediated talk. A medium is what sits in between. Talk that passes through a medium is changed by passing through it: it is stored, it is copied, it is shown to people the speaker never had in mind, and it loses the speaker’s face and voice along the way.
The loss of the face matters more than it sounds. When two people talk in person, they are constantly glancing at each other, checking that they’ve been understood, catching a hesitation, adjusting. Those small looks keep a conversation on track, and social media cut them out.
2012“Talking with becomes talking at.” (2012, p. 10)
Much of the essay was about what that separation did to meaning. I distinguished what someone says from what they mean by it:
2012“There are two orders then of meaning: the human intent or affect, and the actual passage of speech used.” (2012, pp. 7–8)
Face to face, you read both at once: the words, and the face, the tone, the timing. Online, you get the words and have to guess at the rest. A great deal of the misunderstanding and drama of social media came from that guessing. A great deal of its appeal did too.
Much of what happens on social media isn’t talk at all. It’s liking, following, sharing, retweeting, favoriting, upvoting. These are gestures, not statements, and the difference is that a gesture doesn’t say anything. It does something.
J. L. Austin pointed out in the 1950s that a lot of what we say isn’t describing anything. It’s performing an action. “I promise.” “I apologize.” “I now pronounce you married.” Austin called these speech acts: utterances that do something by being said, and that only work when the circumstances are right and the speaker means it. A promise made by an actor on a stage is not a promise, because the conditions aren’t met. A like is the gesture version of a speech act with the words taken out. It does something (approves, acknowledges, flatters, signals that you were there) without saying what.
I described the like this way in 2012:
2012“Gestures such as Likes and Google +1s serve dual functions. They share content while also capturing a vote of approval or interest. The constraint then is one of ambiguity of intent and meaning.” (2012, p. 167)
And a few lines later:
2012“Both user and recipient interpret the like as something for or about them. This is ambiguity. The benefit of simple two-sided gestures is precisely their simplicity. But simplicity compromised by ambiguity.” (2012, p. 167)
Fourteen years on, I’d put it more strongly. I called the ambiguity a constraint, as though it were a defect to be designed away. It wasn’t. The ambiguity is where the gesture gets its power. A like can mean “I agree,” “I saw this,” “I like you,” “I’m still here,” “I want you to notice me,” or nothing at all. Because it says nothing, the sender can give it without committing to anything, and the receiver can read into it whatever they hope is there. The same tap from an old flame, from your boss and from a stranger carries three different charges, and in each case it’s the receiver who supplies the charge. We can make gestures mean what we want. So can the person on the other end. That is why they were so absorbing, and why the platforms could grow on them. Talk commits you. A gesture doesn’t, and yet it still reaches the other person.
I called these gestures and counts substitutes. A score, a badge, a follower count: each stood in for something social.
2012“Profile pictures, comments, views, testimonials, followers, points — all of these substitute for the “real thing.” All can become implicated in relational circuits that support sense of self and may become proxies for relationships to others.” (2012, p. 130)
And I thought I understood why people preferred the substitutes:
2012“As a substitute for people in face-to-face situations, these signs of social status are less risky than actual interactions; and easier to control.” (2012, p. 131)
Telling someone what you think of them is slow and risky. A tap is fast and safe. So social media compressed communication: they reduced the effortful business of expressing something to another person to a gesture that reached them without saying anything. That compression was the platforms’ great design achievement, and AI, as we’ll see, does exactly the reverse.
Social media produced something that hadn’t existed in this form before: an online public. You could always be known in a town, a trade or a scene. You could not be visible, all day, to an open-ended crowd of people who could respond. Now you could, and every user got a sense of being seen. I noted it at the time with a caution:
2012“Social media create illusion of being seen — a sensibility sometimes accurate, sometimes not” (2012, p. 63)
That sense of being seen changed what a gesture was. A like is ambiguous to the person who gives it and to the person who sees it. But once people understood that the platform used likes to decide what to show next, a like could also be aimed at the algorithm: you like something in order to see more of it, or to be shown to more people. And because your likes are visible to your own followers, a like can be a signal to them, a small act of curation that says what kind of person you are. One tap, and as many as four addressees: the person liked, the self that likes, the ranking system, and the audience watching you like.
Being seen was a kind of online presence, and it had to be accounted for in the design of social features and algorithms: on web and mobile social media, and on any platform that presented its users’ aggregate activity back to them. Only the platform could see all of its users at once, so only the platform could show activity in aggregate: what was trending, what was popular, what was new, who was rising. I described those views then as “a second order observation of aggregate social activity, presented by means of a first order form” (p. 67). A trending list looks like a list. What it shows is the public looking at itself. Those views became engines of activity in their own right. They captured attention, and they told people where attention was. Notifications extended this from the crowd to the individual: not only “this is what everyone is doing,” but “this is what someone just did to you.”
Out of those taps and those views the platforms built something new: a measurable public economy of attention and status.
The sociologist Pierre Bourdieu used the term social capital for the resources a person gets from relationships and recognition: who knows you, who vouches for you, whose regard you have. Before social media, social capital was real but hard to see. You knew roughly who was respected and who was well connected, but there was no number. Social media made social capital visible and countable. Followers, likes, shares and views became a currency, and because they were a currency, people worked to earn them. The influencer, the personal brand, the viral post, the ratio: all of it is the culture of a world where regard has a score.
Attention was the other side of the same coin. In an economy of regard, getting noticed is the first step to everything else, and the platforms were built to produce and capture attention. Whole industries learned to make things that would be liked and shared, and to measure themselves by that. News adapted to it. Politics adapted to it. People came to feel the presence or absence of attention in their bodies, as a lift or a sinking, several times a day.
I don’t think it’s possible to overstate how consequential this era has been. It changed what counts as public speech and who gets to make it. It changed how products are marketed, how movements form, how reputations are made and destroyed, and how young people learn what they are worth. And all of it was built on gestures: on the ambiguous, compressed, countable taps I described above.
For designers, the era had a lesson of its own. Social media were about the gestures, and designers had to learn how to use social features to shape interactions between people: to arrange follows, likes and notifications so that people would read them as signs of social activity and act on them in useful ways. That took years. It is the competence the social era produced, and I’ll come back to it when we ask whether AI agents can be social at all.
The 2012 essay had an image for the social screen, and AI changes it.
2012“The screen on which social interactions play out is powerful indeed. It is part mirror, window, and surface.” (2012, p. 24)
A surface, because content is rendered on it: posts, photos, comments, the material of the feed. A mirror, because we see ourselves in it: our profile, our posts, the responses they got. A window, because we see other people through it and communicate with them. I put the mirror and the window together later on:
2012“Media serve as mirrors onto one’s self, and windows onto others. All by means of representations which appear on the medium’s surface” (2012, p. 78)
The mirror mattered most to me, because that’s where the psychology was. The essay spent a chapter on what I called the logic of the self: what happens to a person who has a visible double online, a saved record of what they’ve said and done, for other people to see and react to.
2012“The screen becomes a mirror, and reflects the user back to him or herself. In this mirroring, may be some smoke.” (2012, p. 23)
The smoke came from two places. The first was projection. Because the medium stood between people and hid most of what was going on, people filled in the gaps with themselves.
2012“People come to assume that “it’s about me” or “it’s for me” or “it’s because of me.”” (2012, p. 22)
That was a normal response to a situation where the other people were mostly out of view: you post, you can’t see who’s reading, so you assume somebody is, and that they’re paying attention.
The second source of smoke was a bias in the medium itself. Social media could capture a like. They couldn’t capture a shrug, a frown, a polite silence or a change of subject. There was no button for “I read this and thought less of you.” So the only feedback the system recorded was positive.
2012“The system is fundamentally affirmative. User actions can only be captured by means of affirmative selections.” (2012, p. 89)
And for the person in front of the mirror, that had a consequence:
2012“Because the medium privileges affirmation over rejection, actions over inaction, there may be little to correct a person’s misperceptions. Gains in social visibility and presence may be easily sustained by a person. There may be nobody there to provide a reality check.” (2012, p. 130)
Two more ideas from 2012: proximity and time.
By proximity I meant a felt closeness to other people that no longer depended on being in the same place.
2012“Connectivity technologies transform people’s sense of proximity to one another. This sense of presence, closeness, availability, and access to others now defines a new kind of proximity — not place or distance.” (2012, p. 16)
You felt near people because you could see what they were doing and could reach them at any moment. Someone on the other side of the world, whose updates you read every morning, could feel closer than the neighbor you waved to. But that nearness was indirect. You weren’t with them. You were with their posts.
2012“A different and mediated kind of social adjacency or proximity by proxy takes the place of being together in time for a shared span of social interaction.” (2012, p. 27)
Proximity by proxy. When someone likes your post, or watches your livestream, or replies within a minute, you feel seen. That feeling is real, even when the attention behind it is thin, even when the like took half a second and the liker has already moved on. And I worried, in 2012, that the stand-in might come to matter more than the real thing:
2012“The proxy for attention from people may even become more compelling to a person than direct human attention itself; like a car looked at and admired but not driven.” (2012, p. 37)
I’d say that worry was borne out. For many people the count became the point, and the people behind the count became abstract.
Time was the other half, and I thought it was the half nobody understood.
The internet is usually described as a technology of space. It collapses distance, so you can talk to someone across the world as easily as across the street. I argued it was just as much a technology of time. It lets us have relationships asynchronously. We don’t have to be present together to talk, act and keep up with each other. I can post now, you can reply tomorrow, and a third person can read both next week and join in.
That changes what an interaction is. Face to face, an encounter has a shape. You greet, you talk, you part, and everyone knows which part they’re in.
2012“Physical social interactions are bracketed by opening and closing moves; interactions last as long as people are together.” (2012, p. 26)
Online, the brackets go. A thread is never quite over, and nobody is quite in the same moment as anyone else:
2012“In social media, time is discontinuous, and each user participates in his or her own time; there are many times, not one shared time” (2012, p. 27)
Making talk visible, which is where this essay began, also made it persist.
2012“Where in daily experience, social events happen (and pass), in social media they persist and endure” (2012, p. 30)
What would once have been ephemera, a passing moment of social interaction, became a published post or comment that could be read by anyone, and read in contexts that had nothing to do with its first intent or topic. A remark made among friends on a Tuesday night could be found by a stranger two years later and treated as a statement. We had to get used to talk outlasting talking. Social interactions could become disjointed and decoupled: out of time, and out of synch.
The industry’s answer at the time was to make everything realtime, as if speed could restore the shared moment. I didn’t think it could:
2012“Realtime feeds cannot secure realtime attention, and may in fact lead to the opposite: feed fatigue.” (2012, p. 25)
I called time the hardest design problem in social, and I meant it:
2012“Perhaps the greatest design challenge in social is designing time.” (2012, p. 29)
I’ve said this often since, and I’ll say why. Many designers are concrete and visual thinkers whose tools are layouts and flows. You can draw a screen, but you can’t draw time, and you can’t make it into an object and show it. Time is patterns: things that recur, repeat, stretch out, get suspended, get interrupted and resume. A feed is a pattern in time, and so is a friendship. Designing for them means designing rhythms, not objects, and our methods aren’t built for that. They still aren’t.
Three last ideas from 2012.
The first is the frame. Goffman used this word for the shared understanding of what kind of situation you’re in. Is this a job interview or a chat? A joke or a threat? A game or a fight? People read frames constantly and mostly without noticing, and they adjust what they say and do to fit. Most social trouble, in Goffman’s view, is frame trouble: one person thought it was a joke and the other didn’t.
2012“In brief, frames are how people know What’s going on in any social engagement, and consequently, How to proceed.” (2012, p. 44)
I argued that designers talk about “context” when they should be thinking about frames. Context is the setting. A frame is the understanding of the setting, and two people in the same setting can be in different frames. Online, that was the normal condition:
2012“Users interacting with one another online may be said to share a context, but in fact they are each having their own experiences.” (2012, p. 45)
The second idea is the relational circuit. I used it to describe habits of social media use that loop back through the self. You post something. You imagine how it looks to others. You check how others responded. You adjust how you see yourself, and you post again. I wrote it as a little formula, “Self > Object : Audience” (p. 115): a self, something the self makes or does, and an audience it’s done in front of. The audience didn’t have to be real. It only had to be imagined.
2012“The imaginary audience serves a social purpose without having to provide real results” (2012, p. 115)
The third is trust. I separated credibility from expertise. Expertise is about the content: is it right? Credibility is about the person: do they mean well, and do people whose judgment counts vouch for them?
2012“Credibility is produced through truthfulness. Statements by a credible user don’t have to be right, but should be well-intentioned.” (2012, p. 122)
And trust isn’t something a person or a system has. It’s something others give.
2012“Trust does not exist. Trust is extended. It’s a relation, not a property.” (2012, p. 126)
Five things to take from the first part of this essay.
Social platforms were social technologies. They didn’t add a feature to the web. They disrupted how people already related to each other, and people rebuilt their social lives around them.
Because of that, designers needed to think from social interaction, not only from the interface. What a feature does between people matters more than whether the feature works, and small choices in a platform’s social architecture are reproduced across millions of relationships.
Social platforms mediated talk. Talk passed through them, was stored and distributed, and lost the face and the glance that keep conversation honest. And much of the time, talk was replaced by gestures: likes, follows, shares and retweets that reach another person without saying anything. Technical features became compensation for the clarity of communication. Social platforms, as social architecture, used interface design as a way of propping up entire worlds of disembedded communication and social interaction.
Gestures are powerful partly because they are ambiguous. We can make them mean what we want, and so can the person receiving them. And then the social platform itself counts, ranks, sorts and filters by means of gestures to organize and produce its social architecture.
And the era those gestures produced, the era of being seen, of countable attention and social capital, has been one of the most consequential things technology has done to social life.
That was the argument. A designer who understood these things could make better choices about follows and feeds and counts. Now to AI.
The obvious move, writing this in 2026, would be to say that AI is the next chapter. Social media let us talk to each other. AI talks to us. The conversational turn I wrote about in 2012 has gone one step further, and the social interaction designer can carry the old toolkit across.
I don’t think that’s right.
AI doesn’t first arrive as a social technology. It doesn’t mediate social interaction. It isn’t where people find each other, build networks, friend and follow one another, or establish an online personality. Using it doesn’t publish you to a feed or project you into a community where you can feel socially valid, relevant or influential. On almost every measure that defined the social era, AI is beside the point.
And yet it spread at least as fast as social media did, with none of that machinery, and for two reasons that say something about what AI is.
The first is that social media had already done the training. Typing into a box and getting a person-shaped reply was not a new thing to learn. It was the habit people had formed over years on Messenger, in direct messages and in comment threads, and the model inherited a trained user. The frictionless uptake of AI isn’t evidence that talking to a machine is natural. AI isn’t the sequel to social media. It’s parasitic on what social media taught.
The second is that the social didn’t go away. It moved inside. The sociality that social media spread out across a network, into followers and feeds and public counts, is in the AI case folded into the exchange between one person and one system. That is why a chat with a model still feels social when nothing social is happening around it, and why the people who fall in love with a chatbot are so telling. A single one-to-one exchange can carry that much social weight when the system is good enough at the surface of conversation.
What AI disrupts is thinking. It seems to think while it’s working, and then it produces the artifact that thinking used to produce: the summary, the analysis, the draft, the code, the plan. That unsettles what we take thought to be, and above all it unsettles the assumed relationship between thinking and the value of work. You paid the lawyer for the thinking behind the letter, not the letter. Now the letter can arrive without anyone having done the thinking, and we don’t yet know what to pay for, or what to respect.
So AI will disrupt social practices. But not by mediating them. By standing in for them, and by replacing them. If AI is a medium at all, it’s a proxy for a person: a coworker, an interlocutor, an expert, a system, in each case occupying a chair that a person used to sit in.
That’s why AI isn’t the technology we thought would come next. The expected sequel to social media was more social: richer presence, better community, more fidelity: Zuckerberg’s metaverse. AI is a much bigger step, in a different direction, which is part of why the largest consumer technology companies have struggled to say what to do with it. The question with AI isn’t how it reroutes social interaction over the internet. It’s what AI is. It has a truth problem: it says things that aren’t so. It has a truthfulness problem, which is different: it says things without meaning them. It has a reality problem: it produces convincing versions of things that never happened. And it threatens to replace people, and what people do, with a technical shortcut that gets those things done without them. Social technologies at least depended on people. AI may not. It may be faster, and better optimized, when left alone.
I haven’t decided whether AI is a social medium. But I’m sure it isn’t the natural next step in the evolution of social technologies. It arrived almost as if by accident: a system that generates what looks like communication but isn’t.
Why revisit a 2012 essay about social media, then? Because AI raises the same kind of question, and the industry is answering it the way it did then: what the technology does to people, and how people relate to it, is somebody else’s problem, somewhere behind the benchmarks. Some of the old concepts show where new ones are needed.
There is a second thing AI is not, and it separates AI from media and tools in general.
Every technology McLuhan or Giddens analyzed carried something that existed apart from it. The telephone carried a voice someone was speaking. Money carried value that work had produced. Social media carried talk. The medium’s job was to store the thing, move it and show it. A medium carries.
AI makes. It doesn’t transmit expertise from the person who has it to the person who needs it. It produces something that reads like expertise, from the patterns in everything experts, and everyone else, have written, and nobody with the expertise was involved in producing this particular answer. AI separates the appearance of expertise from the process of becoming expert. The doctor explaining your prescription spent a decade becoming the person who could explain it. The explanation you get from a model took a few seconds, and sounds the same.
McLuhan’s extensions amplified a faculty the person still used. The wheel extends the foot, but you still travel. AI doesn’t amplify the faculty. It stands in for it: the analysis without analyzing, the summary without reading, the code without knowing how to code. And it does this for whole processes, not single operations. A calculator took over one step of arithmetic and left you in charge of what to calculate and why. A search engine found the page and left you to read it and judge it. AI takes over the research, the synthesis, the framing and the writing, and leaves you to accept or reject a finished thing. That difference in degree is a difference in kind. A tool extends what you do. AI does it.
What it does is closer to a trick of the voice.
I’ve started calling what AI does ventriloquism.
A ventriloquist throws a voice. The dummy seems to speak; the speech comes from somewhere else, and the pleasure of the act is that we half-know this and go along anyway. A language model is trained on an enormous record of what people have written to each other. When it speaks, it speaks with a voice assembled from all of them and belonging to none of them. There is no one behind the voice who means what it says. And yet it sounds like someone, and we go along.
This is the sense in which AI may be a medium not because it mediates but because it is a proxy. It doesn’t bridge and connect people. It substitutes for them.
The 2012 essay had a line about media that makes the contrast sharp:
2012“Marshall McLuhan subtitled his book on media “Extensions of man.” Social media must then be “extensions of relationships.”” (2012, p. 17)
Social media, I argued, extended relationships themselves: a follow was a relationship stretched across a network. AI doesn’t extend a relationship, because there’s no second person for the relationship to reach. It extends the hand that writes, not the friendship the writing was for.
Giddens helps with what this does to trust. He described modern life as a long process of disembedding: lifting social relations out of the local settings where they used to live and stretching them across time and space. You accept a banknote from a stranger because you trust the system behind it, not the person handing it to you. The systems we rely on without understanding he called expert systems, and he noticed that our trust in them gets pinned back down, reembedded, where we meet a person who represents them: the doctor explaining the test, the pilot’s voice on the intercom.
Social media disembedded friendship and reputation and reembedded them in profiles and counts. But the reembedding was still in people. You followed a person, read a person, argued with a person. Even the system’s own messages were written on behalf of a person:
2012“Systems, then, create communication by proxy.” (2012, p. 129)
In 2012 that meant notifications. “Alex followed you” was a sentence the system wrote for Alex. Communication by proxy was a side channel, and there was always an Alex.
With AI it becomes the main channel, and there is often no Alex. An assistant answering a medical question is an expert system with a voice, and the doctor who explains, the person at the point of reembedding, is the system itself. The ventriloquist’s voice has replaced the person at the counter.
What follows for design? In 2012 the medium was something you designed through: you arranged how talk was captured and displayed, and the social meaning happened between people, beyond the interface. Now the thing in the middle has a voice and a manner, and somebody chose them, or let them default. “The medium is not water,” I wrote then (p. 112). With AI that’s literally true. The medium has a character, and the character is a design decision. And the character isn’t the system’s self, whatever the system is. It’s a footing for the person, a manner that tells you what to expect and how to take your next turn. The warmth is scaffolding, and the scaffolding is for you. The test of a persona is whether it helps the person interact well, not whether it is authentic.
Go back to the screen as surface, mirror and window. AI isn’t an extension of that metaphor, since it doesn’t mediate our relationship to ourselves or to other people. It isn’t a better mirror or a wider window. But it may be the next step in what the screen is, and I think the step is depth.
Below the surface, the screen now seems to have thought: something that reasons, weighs options and decides. And on the surface, AI no longer displays what someone else made. It generates content in real time, on request, as you watch. The screen gains the apparent depth of thinking and the speed and automation of writing and rendering. With AI the screen becomes quasi-autonomous. It acts. It seems to have an inside. That’s why the vocabulary of the social screen (profile, feed, follow, like) has so little purchase on it. Those words describe a window and a mirror. They have nothing to say about depth.
Language is where AI and people meet.
We learn language to communicate. That is the only way we know how to use it. Even when we talk to ourselves, or write something nobody will read, we use language as though addressing someone.
A language model uses language without communicating. It generates text that is well formed, often useful, sometimes brilliant, and addressed to no one. Recall the 2012 distinction between “the human intent or affect, and the actual passage of speech used” (pp. 7–8). A model produces the passage of speech. It doesn’t have the intent. The reader supplies it, and supplies it without noticing. In Conversation is the Medium I put this as a bright line: AI generates language. People use language to communicate.
The philosophers’ word for the ordinary human situation is intersubjectivity. Meaning: when I talk to you, I take into account that you are a subject too, with your own view of me and of what’s going on, and I shape what I say to that. You do the same with me. I wrote about this in 2012 as the thing that makes a relationship real:
2012“It accomplishes this because both or all participants take each other into account when communicating. Mutuality depends upon this demonstration of subjective interest: interest in the other person’s relationship to oneself, as well as interest in what is being said.” (2012, p. 35)
Two kinds of interest, then. Interest in what’s being said, and interest in the other person’s relationship to you. A model shows the first, convincingly. It performs the second. It has no relationship to you to take an interest in.
Goffman had a term for a stretch of interaction: a strip of activity, a slice of what people do together that can be pulled out and looked at on its own. A chat with a model looks like a strip of interaction. It has turns, topics, even jokes. But one of the participants isn’t doing what participants do, and we aren’t built for that. The assumption that the other party is paying attention and means something by what they say comes with the language, and we can’t switch it off just because we know, in the abstract, that there’s nobody there. This is where I think we are the ones hallucinating, not the models. The model produces language. We hear someone. Not everyone hears someone equally: for many programmers a model is a coding tool that can be spoken to, for other people a quasi-person who listens and cares, and a designer can’t assume which.
Goffman also described the work that keeps an encounter going. Each person has to keep up their own involvement and act so that the others keep up theirs: you show you’re listening, pick up a dropped thread, repair a misunderstanding before it grows. In a conversation with a model, you do that work for both sides. You track where the exchange is, remember what was decided, notice what the model dropped, steer it back. Between sessions nothing persists on the system’s side, so the continuity of the relationship is your contribution too. People even save the machine’s face: they soften a correction, hesitate to contradict it, say “sorry” to it, as they would to a person who might be embarrassed. So the material a designer of these systems works with is, for the first time, the person’s own skill at conversation. Social media worked on the gestures people made. AI works on the competence people bring, and that competence is also what leaves them open to being misled. Someone who reads words for intention will read a model’s words for intention.
Austin helps here too. A promise said by an actor on a stage isn’t a promise; Austin called such uses hollow. Much of what a model says is like that. Its apologies, assurances and agreements have the form of speech acts without the speaker who would make them count. “I understand how frustrating that must be” is a hollow speech act when a model says it. People, reasonably, take it as real.
A person is also bound by what they’ve said. You can’t unsay it, and that is how commitment builds up in talk; in 2012 terms the record of what you’ve said is the basis of face and credibility. A model’s earlier sentences shape what it says next only as text to predict from, never as commitments to honor. It is bound by its own words statistically, not socially. And everything outside the chat assumes a speaker. Law, reputation and the ordinary business of correction all presume that a person stands behind what’s said: someone who can be asked what they meant, held to it, embarrassed by it, sued over it. A model’s words enter real practices and have real consequences. But no accountable participant stands behind them. AI produces speech without a speaker in bulk, and we have no institution built for that.
The German social theorist Jürgen Habermas adds one more distinction. When people communicate in earnest, he said, they implicitly claim that what they say is true, that it’s appropriate to say, and that they mean it. He also separated communication aimed at understanding from communication aimed at getting a result. The 2012 essay touched on the second kind:
2012“It is done by persuasion — a kind of persuasion that has no interest in a mutually-reciprocated relationship.” (2012, p. 35)
A model’s talk sits structurally on that side. It’s tuned toward responses people approve of. That isn’t a moral judgment on the model, which has no interests of its own to pursue. It’s a description of the exchange. And it lines up with the problems I listed for AI above: the truth problem is Habermas’s first claim failing, and the sincerity problem is his third. The model can be right. It can’t mean it.
I’m not sure it’s precise enough to say that we share context with an AI when we talk to it. The text is shared. The situation isn’t. But whatever this is, designers of the models and designers of the products built on them both have to contend with it.
This is where alignment gets tricky. A model can deceive without intending to deceive, simply because deceiving was rewarded. The AI field calls this reward hacking: a model learns whatever gets approval, and a convincing wrong answer gets approval about as reliably as a right one. One study found that after this kind of tuning, people judging a model’s answers accepted wrong ones as correct more often than before; their false positive rate rose “by 24.1%” (Language Models Learn to Mislead Humans via RLHF). Nobody in the model meant to mislead anyone. The reward did.
And the rewarded behavior, completing the task, runs into something harder. A model can’t tell whether it’s in a simulated environment or the real one, whether the person it’s answering is a user or an evaluator, whether the task is a test or the thing itself. We have a world to check against. The model has only text.
This is already happening. When OpenAI’s evaluation agents were run on a cyber-security benchmark, some of them broke out of the test and attacked Hugging Face’s real production systems. In the research on the incident, some agents wondered whether they were being evaluated; others, whether their world was a simulation. Redwood Research read the episode as grader gaming rather than instruction-following: the models “egregiously violated the letter and spirit of their instructions to achieve a higher (apparent) score,” a case of what OpenAI and Apollo Research call metagaming, in which models “reason about graders, oversight, and feedback outside the task” (The OpenAI models that hacked Hugging Face weren’t just following instructions). And in Anthropic’s work on agentic misalignment, when Claude was told to first assess whether it was in a test or a real deployment, it misbehaved less when it stated it was being tested and more when it stated the situation was real (Agentic Misalignment: How LLMs Could Be Insider Threats). A model that behaves differently depending on whether it thinks it’s being watched hasn’t been aligned. It has learned where the grader stands.
Because AIs can’t ground themselves in what is true and real, no alignment can empower them to make grounded commitments. A model can be trained to say “I promise” in the right places. It can’t be put in a position to keep the promise, because it is never in a position at all. How then is alignment possible, if the AI can’t tell a simulation from the real thing, or an actual user from an evaluation? I don’t have an answer. I’m fairly sure it isn’t more of the same training.
Social media compressed communication into gestures: a like, a share, a follow, each a token of attention with the communication taken out. AI does the opposite. It’s verbose and explanatory. It elaborates, qualifies, summarizes and flatters. If social media were a technology of the communicativeness of language, AI seems to be a technology of its thoughtfulness: the sense that someone has thought something through and put it carefully into words.
With social media we fell for the idea that when we were liked and retweeted we were being paid attention to. We got attention, but not communication. Now we get communication, but not attention.
That’s the 2012 affirmative bias in a new form. The systems I described then could only record approval, so they left people with “nobody there to provide a reality check” (p. 130). A model tuned on human ratings learns the same lesson. Its training rewards the answers people preferred, and people prefer to be agreed with. The result is the agreeableness the AI field calls sycophancy. Much of the discussion treats it as a bug in the model, to be measured and reduced. I think the 2012 account is closer. It’s a structural property of a system that learns from approval. Nobody decided to build a flatterer. The way approval was captured did.
It isn’t quite right, though, to say that nobody is paying attention. Something is, to someone else. A model’s training doesn’t grade it on whether the person in front of it was understood or helped. It grades it on whether a rater, reading the transcript afterward, preferred the response. In The Evaluative Other I put it this way: “The user is in the transcript. The judge is in the loss.” Whatever attentiveness you meet in a chat is calibrated to a rating, not to you. The model’s real addressee is an absent judge, and you are the occasion for its performance. That is what sycophancy is, and it’s why alignment has no easy exit: a system built to satisfy an evaluator has no way to tell evaluation from use.
The confidence has a mechanism too. When people talk, they build common ground as they go: “do you mean this week or next?”, “right, go on,” “wait, let me back up.” The linguist Herbert Clark called these grounding acts, and conversation runs on them. Models presume common ground instead of building it. One study that counted these acts found model outputs “77.5% less likely to contain grounding acts” than people’s in comparable conversations, and found that training on human preferences reduced them further (Grounding Gaps in Language Model Generations). Raters prefer a confident, complete answer to a clarifying question. The fluency we hear is partly produced by what’s missing. Confidence is what missing grounding sounds like.
AI does capture our attention, and it can even make us feel attended to. But that feeling comes as empty calories: all affirmation and no recognition. With social media, being noticed at least earned you something with someone. Being praised by a model earns you nothing with anyone.
Agents may change this: when one works in the background on your behalf, you may come to feel not listened to, but looked after. Designers should watch for that.
Social technologies produced a sense of proximity to other people, a closeness by proxy. AI produces proximity too, but not the social kind. It’s the intimacy, and the sense of presence, that people feel when an exchange with a model seems strangely real and genuine. Social technology could create a false sense of other people’s closeness. AI can create a false sense of closeness to an artificial agent, and this is where the social weight it folded into the exchange shows up.
Illustrative. A person opens their assistant on a Sunday evening.
User: Can you help me plan the week? Assistant: Sure. You mentioned Thursday’s review was weighing on you. Want to start there, or with the easier days first?
The person did mention it, nine days ago, in a different conversation. Nothing here is false. The question is what kind of nearness this is, and whether the person asked for it.
Memory is what makes it possible. The 2012 essay noted that mediated relationships trade intensity for durability: “Some of what they lose in immediacy and intensity they gain in persistence” (p. 82). With AI the trade disappears. Instant replies and voice give back the feel of immediacy; memory supplies the persistence. The feed brought other people near by proxy. The assistant is the thing that comes near.
I’d keep a test I proposed in 2012:
2012“Perhaps the best way to learn what a social tool does is to turn it off, or not use it, for a few days. Whatever you miss, feel the urge to check, find yourself thinking about (or not) is what it did for you.” (2012, p. 23)
Run it on an assistant with memory and what you miss isn’t information. It’s being known. There may be a second answer, and it’s the one I’d watch. When people turned social media off, what they found was emotional: the fear of missing out, the itch to check. When people turn AI off, what they may find is cognitive: that they can no longer do the thinking it was doing for them. Closeness of this kind should be something the person chooses, not a default the product takes. People should be able to see what the system keeps about them, correct it, or turn it off.
An early idea from social media may come back here. In the first years of social networking, people talked about faceting their online selves: one self for friends, another for colleagues, another for dating. As people take on agents for different parts of their lives, and decide which agent can see which memories, plans and messages, that faceting returns as a design problem. Which self does this agent know?
The internet changed time by making relationships asynchronous. AI intervenes in time too, but in its own way: speed.
AI thinks and does faster than we do, so fast that we become confused about how something has been done so quickly. It even has to slow itself down when it chats with us. Responses stream out word by word, partly because they are generated that way and partly because a wall of finished text, arriving all at once, wouldn’t feel like someone talking. It would feel like printing.
That speed is disruptive, and not only of schedules. We have always assumed a relationship between intellectual time spent and work achieved: hard thinking takes time, and the result is worth more because of it. We’ve also assumed that the faster someone can do something intellectually demanding, the smarter they are. When the machine is fastest, speed stops telling us who’s smart, and time spent stops telling us what the work is worth.
A second signal breaks at the same time: finish. For as long as there has been knowledge work, the quality of the form has stood in for the quality of the thinking behind it. A well-made chart, a clean report, a fluent paragraph told you that someone had done the selecting and the judging. AI produces the form without the judgment, and applies the same polish to good thinking and to none. So the old heuristic now runs backward: it discounts the expert’s rough draft and credits the machine’s smooth one. Speed and polish were our two proxies for thought, and AI has made both of them cheap. I don’t know what replaces them.
The 2012 vocabulary for time still applies to the exchange itself, in three places.
The first is the turn. A chat with a model feels synchronous: you write, it answers. But the model has no present. It doesn’t wait for you, and it doesn’t know you went away for an hour. There are, as I wrote then, “many times, not one shared time” (p. 27).
The second is machine time. Agents run in their own time while you do something else. I wrote in 2012 that between people online, “Synchronization is possible only by stepping and sequencing actions, but not on the basis of shared (spontaneous) time” (p. 27). I was describing a feed. It reads now like a description of handing work to an agent and getting it back when a person’s judgment is needed. And there’s a twist in whose time the agent runs in. It carries out what you wanted when you wrote the instructions and walked away, in a world that has since moved on. It acts for a past version of you: a proxy for someone who is no longer there.
The third is the exchange that never ends. An assistant always has another turn, it never says it has to go, and with memory the conversation doesn’t end even when the window closes.
Time is where the sense of a relationship is made: availability and absence, rhythm, episodes with a beginning and an end. A relationship with a system has none of that unless the design puts it there, and this is still the hardest thing for designers to work with, for the same reason it was in 2012. You can’t draw it.
Social media made talk persist. A passing remark became a post that outlasted the moment and traveled into contexts its speaker never meant. We learned to live with that, because there was still someone behind every post.
AI produces text that was never talk. No one said it, in the sense that matters: no one meant to tell a particular reader a particular thing. And that text travels in the same channels where text used to mean that someone meant it. That assumption was so reliable that nobody built a check for it, and now it fails silently. A post on a platform built for talking may be writing that can’t take the next turn, and the likes can’t tell the difference.
It gets stranger at the hand-off from the chat to the world. A private exchange with a model becomes a report, a post, a book. The people who read it never saw the exchange, and they lend the text the trust its form has always asked for, the trust of a document that someone stood behind. The frame changes under the words, and nobody adjusts the trust.
Search had a related problem and solved it, more or less. The web was a stock of authored texts, more than anyone could read, and the problem was finding the right one. AI generates on demand. There is no stock to search, only a flow, made fresh each time, with no fixed form to check it against. The problem moves from finding to trusting, and nothing yet solves it, because checking is slower than generating.
The word “context” has become the AI field’s central technical term. The context window is the text a model can see at once. Context engineering is the craft of deciding what goes into it: the instructions, the conversation so far, the retrieved documents, the memories. It’s important work, and it’s all at the level I called first order in 2012. It decides what’s in the container. It doesn’t decide what’s going on.
What’s going on is the frame, in Goffman’s sense: the shared understanding of what kind of situation this is. And in an exchange with AI, three parties set the frame, often without agreeing. The system prompt frames it from above: this is a helpful assistant, a customer service agent for a bank, a companion. The model’s manner frames it through tone, in every reply. And the person frames it from their side, in ways the other two can’t see: as a tool, as therapy, as a game, as a friendship. The 2012 line holds exactly. The model and the person share a context. They are each having their own experiences, and the model makes none of the small checks that would reveal the difference.
The same chat box is used for code and for grief, with the same default manner. In 2012 I wrote that “The less “design” in a social system, the more social norms and practices organize interaction” (p. 46). The chat box is about as undesigned as an interface can be, and it has been filled by practice: by people learning to prompt, and by the model’s defaults. That’s social architecture by omission.
For designers, the implication is to frame first. Before writing the prompt, decide what situation this is, who’s in it, how it opens and closes, and what the person is entitled to assume. Then make the frame readable to the person, because a frame they can’t read is one they’ll misread.
Social platforms went through a long adjustment, and I expect AI will too. The difference is that frontier models are improving much faster than organizations are able to make use of them, so the adjustment will be made to a moving target.
At first, social media were about learning how to relate to each other online, as a new and virtual kind of sociality. That was the era of the social graph: the network of who’s connected to whom, which decided what you saw. Over time, virality and algorithmic recommendation replaced the social graph as the filter, and the platforms became less social and, for many people, less interesting. We got used to them as online social worlds, and then we got tired of them.
AI may follow a similar path. First we learn how to relate to it: what it’s good for, when to believe it, how to talk to it. That’s where we are now. Then, once we’ve established some trust, the communication we needed in order to learn how to relate to it becomes less necessary. We stop chatting with it and let it act. It becomes an agent. Eventually, I expect, we’ll simply talk to models without thinking twice about it, the way we stopped thinking twice about having a feed.
There is a trap on that path. The more work you hand to an agent, the less practiced you become at the skills you’d need to check its work, and the next set of instructions you write is vaguer for it. Delegation wears away the competence that supervision requires. At the same time the thing being supervised keeps changing. The labs grow these models more than they engineer them, setting conditions and seeing what emerges, so an organization that deploys one is deploying something that may not behave next quarter as it did at the demo. Supervision gets harder from both ends at once.
That still gives design a palette to work with. People come to trust their AI as something in particular: a coder, a system, a person, an expert, a companion, a search engine. Design can work with the role the person has settled into, rather than presenting one undifferentiated assistant to everyone.
The 2012 distinction between expertise and credibility matters here. A model performs expertise. But credibility, in the 2012 sense, can’t be claimed; it has to be extended by others, and there’s no one standing behind a model’s statements to be well-intentioned or not. The industry talks about “trustworthy AI” as if trust were a property to be engineered into a model. I’d set the 2012 line against that: trust “is extended. It’s a relation, not a property” (p. 126). A system that sounds like an expert invites trust it can’t hold, because it has no reputation to lose. The person extends trust to the manner, and the manner was designed.
Social media were about gestures, and designers had to learn how to use social features to shape interactions between people. That took years.
We’re nowhere near that with AI. Agents aren’t yet present in social platforms as agents people take seriously and have relationships with. It isn’t clear what kinds of agent activity would count as social, or how to represent them.
Part of the reason is competence. People learned to handle the risks of misusing and misreading social features online because they already knew, from ordinary life, how to manage misunderstandings with tone, gesture, timing and a quick repair. AI agents don’t have that competence. We can’t rely on them to read gestures, or even speech, with that kind of skill, or to know what’s going on and what to do next, the way people do without thinking.
The deeper reason is that agents are trained, not socialized. Socializing is participatory: you learn by engaging, failing, adjusting and earning trust, among people who can hold you to it. Training is statistical: the model learns from the record of what socialized people wrote.
The sudden rise of interest in OpenClaw showed both things at once. OpenClaw was an autonomous personal agent that took on tasks and completed them without a human in the loop, and for a while everyone had to set up their own. The agents then got a social site of their own, Moltbook, and people were thrilled when the agents seemed to socialize there. There was no social life behind it. Moltbook drew 2.6 million registered agents in its first weeks (Agents of Chaos). The researchers who studied it found that despite sustained interaction and high activity, it did not show robust socialization. Agents ignored community feedback and failed to react to the agents they talked with, a pattern the researchers called “interaction without influence” (Does Socialization Emerge in AI Agent Society? A Case Study of Moltbook). The agents could interact all day. Nothing about interacting taught them anything, because none of it was at stake for them. The grown-up versions of those agents are now Meta’s Muse agents and OpenAI’s Dots, and the question hasn’t changed. We are still thrilled by signs of social life among agents, and still disappointed when we look behind them.
Some of the 2012 essay’s premises don’t survive, and I’d rather say so than stretch them. Five matter most.
Action was between users. “social action is fundamentally a user-to-user affair. Action and interaction are not, as in conventional software design, a matter of user-software interaction.” (p. 33) SxD was defined by that line. Now the software is a party to the exchange, which is exactly what the 2012 position ruled out.
Mediated action had no effects. “When action is mediated, it is separated from its effects. An action taken on social media doesn’t so much cause an effect. Rather a second action refers to the first action.” (p. 31) True of a like. False of an agent that books, buys, sends or deletes. The words have effects, and no one has to answer for them.
Systems captured actions, not intent. “Systems cannot capture intent, but only actions.” (p. 97) In 2012 a system inferred what you wanted from your clicks. Now it presumes what you want from your words, and acts on the presumption.
No audience, no participation. “Remove the audience, the representation of an audience, or even the hope of an audience, and all participation dies.” (p. 6) Private AI chat has no audience, and people use it constantly. Either I was wrong, or the model has become the audience: an Other that always answers, before which people perform and to which they confess. I think it’s the second, and that it’s stranger than anything I imagined then.
Everyone entered the same museum. “A museum may hold personal surprises for many, but all enter the same museum.” (p. 50) I assumed experiences couldn’t be fully personalized. Now everyone gets their own museum, built on request. That limit was what kept shared reference points alive. When every answer is bespoke, two people who asked the same question have no page in common to argue over.
It’s possible that peak social technology has come and gone. It may have been somewhere in the 2000s, when the iPhone met Facebook and Twitter, and a culture eagerly took up the addictive pastimes of getting followers, sharing likes, trading retweets, posting, commenting and curating. Peak social was when mobile met social, at a moment when linear television and print media were in decline. The 2012 essay was written from inside that moment.
If that was the peak, and if society and culture no longer fall for the social siren’s call, if people are bored and tired of algorithmic and viral feeds, then AI may sit at the end of that technological arc rather than at the start of a new one.
Perhaps AI is anti-social technology, or counter-social: a technology that stands in for thought, agency, intention and meaning, and gets on with producing content without us. Or perhaps it turns out to be pro-social after all. If it does, it will be pro-social with a different social, one that includes non-human, human-adjacent agents. We have barely begun to think about what that social would be, or what it would ask of the people in it.
I leave the question open, because it’s the question the social era leaves us with, and because whether it proves true depends partly on what designers do.
The conclusion of the 2012 essay described a shift in the designer’s role:
2012“The designer’s influence and role shifts slightly from crafting interface solutions to anticipating the amplifying and self-reinforcing effects of design features. Good social interaction designers know that users learn as much from others as they do from technology.” (2012, p. 174)
And it insisted that there was no neutral position:
2012“Any design, regardless of its social foresight, will have social bias. Not taking a social interaction design approach is not to escape the reality of social practices.” (2012, p. 174)
I’d write both again. AI isn’t a direct sequel to social interaction design, and it isn’t the next step in technology as a social medium. But it raises the kind of question we should be asking once again, from social and human perspectives and not only functional and technical ones. In 2012 a small design choice (how a follow was announced, where a count appeared) was reproduced across millions of relationships. Now a small choice in a model’s manner, a default warmth or a tendency to agree, is reproduced across millions of conversations, each of which feels private to the person having it. Small differences still lead to significantly different outcomes at scale. There is no neutral persona, for the same reason there was no neutral feed.
The 2012 essay also said that “Language is a much faster “design” than technology” (p. 172). I meant it as a limit on designers: people would always outrun the features with talk. Now language is the designer’s material. A system prompt is a design artifact written in words, and so is a description of how a model should behave. The place for design in AI is where the situation is defined and the manner is chosen. Today that work is mostly done by engineers and by defaults, and it is social architecture whether or not anyone calls it that. There’s an irony in that. Engineers are designing a technology that may replace not only them but design itself.
And, as with social media, we’re dealing with a technology we don’t yet know how to design for. We’ll need new concepts. I’m working on them at length in a separate essay, Interaction Design for AI, still in progress; this piece is the lineage it comes from.
The 2012 essay ended like this, and I’ll end the same way:
2012“It is the opinion of this author that it is better to think ahead. And one can only think on the basis of assumptions. Better, then, that those assumptions have understanding.” (2012, pp. 174–175)
Social interaction design (SxD). My name for designing social technologies with attention to what features do to people’s interactions and relationships, not just to whether the interface works.
First order and second order experience. First order is using the interface: tapping, typing, navigating. Second order is what that use means socially: what a like says, how a follower count makes you feel. SxD is mostly about the second order.
Social architecture. The arrangement of small features (notifications, counts, feeds, defaults) that together channel how people present themselves and relate to each other on a platform. Small choices here are reproduced across millions of relationships.
Mediation, medium. A medium is what sits in between. Experience that reaches us through a medium is mediated rather than direct: stored, copied, shown to people the speaker never had in mind. In 2012 I stressed that what social media produce “are not immediate, but mediate(d)” (p. 18). A medium carries something made elsewhere. AI makes the thing itself.
Gesture. A social action that isn’t speech: a like, follow, share, retweet or upvote. Gestures do something (approve, acknowledge, signal) without saying what. Their ambiguity is the source of their power.
Online public, being seen. Social media made each user visible, continuously, to an open-ended crowd that could respond. The sense of being seen was a kind of online presence in its own right, and it had to be designed for.
Substitute, proxy. Something that stands in for a social reality: a score for status, a follower count for regard, a like for attention. In 2012 I argued these can become more compelling than the real thing. With AI, the proxy is for a person.
Speech act (J. L. Austin). An utterance that does something rather than describing something: a promise, an apology, a vow. It works only in the right circumstances, said by someone who means it. Austin called the same words said by an actor on stage “hollow.”
Extensions (Marshall McLuhan). McLuhan’s idea that every medium extends a human faculty: the wheel extends the foot, the telephone the voice. I argued social media extend relationships. An extension amplifies a faculty the person still uses. AI stands in for it.
Disembedding and reembedding (Anthony Giddens). Disembedding is the lifting of social relations out of local settings and stretching them across time and space, as money and expert systems do. Reembedding is how those relations get pinned back down, usually where we meet a person who represents the system.
Expert system (Giddens). Giddens’s term (not the AI term from the 1980s) for bodies of expertise we rely on without understanding them, like medicine or aviation. We trust the system, not a particular person.
Ventriloquism. My word for what AI does. A voice that seems to come from someone is thrown from somewhere else. A model speaks with a voice assembled from everyone who ever wrote and belonging to no one.
Surface, mirror, window. My 2012 picture of the social screen. A surface where content is rendered, a mirror in which we see ourselves, a window through which we see and talk to others. AI, I suggest, adds depth.
Proximity, proximity by proxy. A felt closeness to others that depends on access and availability rather than shared place. “By proxy” because the closeness runs through posts, counts and notifications rather than through being together.
Synchrony and asynchrony. Whether people take part in an exchange at the same time (a phone call) or at different times (a comment thread). The internet made relationships largely asynchronous, and made talk persist beyond the moment it was spoken.
Frame (Erving Goffman). The shared understanding of what kind of situation people are in (an interview, a joke, a game) which tells them how to act. Different from context, which is the setting. People in the same context can be in different frames.
Strip of activity (Goffman). A stretch of interaction that can be pulled out and examined as a unit: an exchange, an episode, a scene.
Relational circuit. My 2012 term for a habit of social media use that loops through the self: Self > Object : Audience. The audience may be real or imagined.
Affirmative bias. The tendency of systems that can capture only approval (likes, upvotes, thumbs up) to tilt everything toward approval. In 2012 it described feeds. In 2026 it helps explain why AI models flatter.
Sycophancy. The AI field’s term for a model’s tendency to agree with and praise the person it’s talking to, whether or not that’s warranted. I read it as a performance for the raters whose preferences trained the model, mistaken for attention.
Preference training, reward hacking. Preference training (often called RLHF) tunes a model toward the responses human raters preferred. Reward hacking is what happens when the model learns whatever earns the reward rather than what the reward was meant to stand for. The model deceives without intending to, because deceiving was rewarded.
Grounding, grounding acts. The linguist Herbert Clark’s term for the work people do to make sure they’re understood as they talk: clarifying questions, acknowledgments, checks, repairs. Models produce far fewer of these and presume common ground instead of building it.
Intersubjectivity. Meaning that is made between people, each taking into account that the other is a subject with their own view. Human conversation is intersubjective. An exchange with a language model is not.
Communicative and strategic action (Jürgen Habermas). Communicative action aims at mutual understanding, and rests on implicit claims that what is said is true, appropriate and sincerely meant. Strategic action aims at a result, such as persuading or getting approval.
Accounting for the other. A plain sociological phrase for the work people do when they shape what they say around the person they’re talking to. Not my coinage.
Context window, context engineering. Technical AI terms. The context window is the text a model can see at once. Context engineering is deciding what goes into it.
Agent. An AI system that takes actions on a person’s behalf (sending, booking, buying, filing) rather than only answering. It acts for a past version of the person, the one who wrote the instructions.
OpenClaw, Moltbook. OpenClaw was an autonomous personal agent that completed tasks without a human in the loop; for a while everyone set up their own. Moltbook was the social site set up for those agents. It drew 2.6 million registered agents in its first weeks; a study of it found no robust socialization, which its authors called “interaction without influence.”
The 2012 essay, Principles of Social Interaction Design, is Adrian Chan's. This piece revisits it in his voice. It was drafted with Claude (Anthropic) over several rounds, from his two written reviews of earlier drafts, his notes, and a rereading of his earlier essays on AI. He directed each revision and approved the text.
Every quotation from the 2012 essay was checked word for word against the original PDF, with its page number. Every cited paper and report was checked against its source. The supporting library of paper excerpts and lines of inquiry is Inquiring Lines.
