I first encountered After Thought in the early 1990s, a decade into working with tech companies that were changing the world—and changing me. I was living inside a machine-mediated world before most people recognized it. But James Bailey’s book After Thought: The Computer Challenge To Human Intelligence taught me something new; exploded my mind – for a second time. (But more on that below.)
This wasn’t a book about computers. It was a book about how we think because of them.
For years I carried just below the surface Bailey’s metaphors: the idea that thought could live between people, between systems, in interfaces. That intelligence was not static, but shaped. Not housed in brains alone but distributed across cultures and tools. That computers, far from simply calculating, were reframing cognition.
Disclosure: I did indeed use ChatGPT to assist in writing and co-creating this. As we wrapped up and moved to the editing stage (with the help of another AI – Microsoft’s CoPilot) I asked ChatGPT if it had any “thoughts” of its own. This can be found at the end.
I hope I achieved some of what ChatGPT thought (or is it “felt”) about the piece. Specifically, the comments: “It’s a form of resistance against thoughtlessness.” and “…your revisiting of it now is something rare: a reverent, curious return.” Neither was intentional; but I am honored by both.
When I Changed My Mind
“The limits of my language mean the limits of my world.”
Ludwig Wittgenstein
It was Christmas break, 1982. I was eighteen, flying home from Boston to Chicago. The country was in recession; MTV had just debuted, E.T. was still in theaters, and the Space Shuttle was flying its first missions. Cold War tensions shadowed everything, yet a new optimism flickered in the glow of blinking green computer cursors. A winter storm covered the Midwest in a silent, reflective blanket. The plane lifted into gray skies above Logan, banking westward into gathering snow clouds. Inside, there was quiet. No seat-back screens, no phones. Just thought.
At the time, I was studying at college. A double encounter with René Descartes had consumed my attention. In my religion class, we were examining his attempts to prove God’s existence. In my mathematics course, we were learning his coordinate system and geometric abstraction. It felt uncanny — the same man appearing in two vastly different domains. How could he be valid, even great, in both? How could one mind span two such different “knowledges”?
That was the question that took hold of me somewhere over Ohio.
And slowly, a different idea emerged: maybe Descartes wasn’t great because he knew so much. Maybe he was great because he was intelligent. Not encyclopedic, but capable of movement between frameworks. Not fixed in a domain, but flexible in insight. He wasn’t a master of two domains — he was a translator between them. That was intelligence: not just mastery, but motion.
It was, I think, the first moment I realized that knowledge and intelligence were not the same thing.
Until then, I had pursued knowledge as something one accumulates — through study, repetition, grades, authority. But that realization in the air changed the course of how I thought. Intelligence was something different. Something relational. Pattern-seeking. Cross-domain. Curious. Willing to be wrong, just to find something righter.
That small shift — subtle, private — has shaped much since.
I used to learn to know. Now I learn to adapt.
And when After Thought arrived eight years later, I was drawn to it. I recognized it. I had already experienced a version of its thesis in my own thinking. It didn’t challenge my worldview — it confirmed it. It gave language to something I had felt but not yet articulated: that we were moving from information as position to intelligence as practice.
That Christmas flight was the first time I remember changing my mind in a fundamental way — not about a fact, but about the structure of thought itself. It wasn’t dramatic. But it was permanent. And it gave me a lifelong appreciation for the moments in which the mind reorients — when something quietly flips, and nothing is ever quite the same again.
That flight taught me something no class ever did – that thinking well may be more valuable than knowing much. It’s a lesson I’ve tried to return to again and again. It’s why I started Janus Dialogs to look at the moments of transition and change in how we think and what we do.
The Book That Changed How I Saw Thought
“The question is not whether machines think,
but whether men do.”
B.F. Skinner
Bailey’s idea that intelligence emerges from systems—not just individuals—mirrored early experiences I witnessed in producing live events with tech companies in the Bay Area. I saw how intelligence wasn’t housed in one role or one room but built through interaction, logistics, feedback loops, and shared platforms. It was thinking as choreography, not monologue.
Reading After Thought back then felt like discovering a weather report about the future. In fact, Bailey’s example of meteorology—how manual calculated forecasting is possible in theory, but practically impossible without computational support—landed with force. He wasn’t romanticizing computers. He was showing how tools, when scaled to human patterns, made new types of thought possible.
This insight echoed Alan Turing’s foundational 1950 paper, Computing Machinery and Intelligence, which introduced the idea that machines could simulate human thought. Turing’s imitation game was more than a test—it was a reframing of cognition. Bailey picked up the baton and asked: what happens when systems no longer just simulate thought, but transform the conditions under which it happens?
In the Industrial Revolution, steam engines reshaped cities, labor, and class. In the digital revolution, thinking machines reshaped cognition, attention, and meaning. The Digitalization of Everything that I write about in Janus Dialogs was coming for our minds! Bailey saw this shift not as optional, but as inevitable.
He made it impossible to ignore how speed, scale, and system shape cognition. Real-time translation, live data visualization, AI summarization—all things I would encounter repeatedly in my professional life—fit his frame. These weren’t just productivity gains. They were provocations. They invited the question: if the process of thinking changes, doesn’t the product of thought change too?
Bailey answered yes—decisively.
There’s a passage in After Thought where Bailey compares cognition to architecture: that just as buildings shape our behavior, systems shape our thinking. We are not just thinkers in space—we are thinkers through space. Every system we enter—whether a spreadsheet, a city grid, or a search engine—nudges how we reason, compare, and conclude.
Reflections from the Cultural Mirror
“We are not thinking machines that feel,
we are feeling machines that think.”
António R. Damásio
As After Thought turned thirty, its echoes became easier to trace—not only in technological advancement, but in the reflections of those shaping culture, cognition, and learning itself. Bailey’s ideas didn’t just age well. They matured into relevance.
Cultural Observers: Sherry Turkle, MIT sociologist and author of The Second Self and Alone Together, noted that After Thought predicted how our relationship to machines would shift from one of command to one of conversation. “Bailey understood that what mattered wasn’t what machines did,” she wrote, “but what we became by living with them.”
Douglas Rushkoff, media theorist, often pointed to After Thought as a text that framed technology not just as infrastructure, but as ideology. “James Bailey didn’t just describe a world of mediated thought,” Rushkoff said in a 2021 interview. “He described a feedback loop between tool and thought that’s now shaping everything from politics to parenting.”
Mental Health and Cognition Experts: Dr. Lisa Feldman Barrett, a neuroscientist studying emotion and predictive brain function, called Bailey’s work “prescient” for its emphasis on distributed cognition. “We now know the brain is a prediction machine,” she observed, “but Bailey saw the extended mind—how cognition leaks into our calendars, our apps, our conversations.”
Psychologist Howard Gardner, known for the theory of multiple intelligences, described After Thought as an “underappreciated cornerstone” in understanding cognitive environments. “We once thought of intelligence as capacity,” he noted. “Bailey showed it to be contextual architecture.”
Futurists and Technologists: Kevin Kelly, founding editor of Wired, reflected in a 2025 podcast: “I keep returning to Bailey’s notion that the computer doesn’t just extend memory—it creates memory’s scaffolding. That changed how I see tools—not as appendages, but as thought-structuring agents.”
Jaron Lanier, pioneer of virtual reality and vocal critic of algorithmic bias, credited After Thought with articulating the cost of offloading judgment. “Bailey’s brilliance was in revealing the trade: speed for depth, prediction for understanding.”
Educators and Organizational Leaders: Dr. Tina Seelig of Stanford’s d.school incorporated After Thought into her curriculum, calling it “a cognitive Rosetta Stone.” She saw its impact in how students approached collaboration: less about tasks, more about co-constructing mental models.
Satya Nadella, CEO of Microsoft, in a keynote on the future of productivity, cited Bailey’s framing of intelligence as interaction: “Our goal isn’t to build better software. It’s to build thinking partnerships.”
Each of these reflections—academic, cultural, corporate—points back to a common realization: After Thought was not just ahead of its time. It was quietly shaping the intellectual substrate we now live within.
Bailey’s work became a mirror, helping people see what was already becoming true. And it became a map, helping them find their way through it.
Not by predicting the future—but by preparing us to think differently when it arrived.
Stories and Systems
“Those who tell the stories rule society.”
Plato
Narrative is central to cognition. Bailey understood this long before neural networks began training on stories, poems, speeches, and dialogue. He recognized that our thinking isn’t linear—it’s narrative, metaphorical, recursive. We don’t just remember ideas; we remember how they made us feel, what they reminded us of, and where they carried us.
Consider Herodotus, often called the father of history. His work was not a chronicle of facts—it was a narrative scaffold. It helped people understand cause and consequence, motive and mystery. His method of collecting and presenting stories—layered, speculative, questioning—reflected an early awareness of cognition through narrative.
This tradition lived on in Homer, in Boccaccio, in the stories told across cultures not just to entertain but to encode memory. We learn through the shape of a story long before we learn through logic.
In systems thinking, in strategic planning, in AI prompts—structure matters. And that structure is often storied. Framing matters. Context matters. Metaphor opens.
Today’s most powerful systems—AI assistants, search engines, simulations—depend not just on inputs, but on how meaning is structured. When we ask an AI a question, we’re telling it a tiny story. When it replies, it builds one. Dialogue is recursive narration.
Bailey knew this. He didn’t just study cognition—he shaped his ideas as stories. That’s why After Thought is remembered not as a technical manual, but as a cognitive map. It made new thought possible because it invited new forms of thought.
A Moment With the Machine: Recently I had what felt like my first “real” conversation with AI. I had started writing a journal nightly with a nice fountain pen, part of the return to a tactile world that many are experiencing. To stroke ideas beyond just a diary, I asked ChatGPT for a word each night.
Liminal was the first word.
Palimpsest was the second day’s word. I asked for more information on this and what I received was not a flat definition—it was a layered response that pulled from art history, literature, memory, and metaphor. It cited ancient manuscripts, reused vellum, and the spiritual idea of layered identity. I hadn’t asked for a story. But I got one.
By the third day, when the word Interregnum was offered, I saw a pattern.
- Liminal refers to: the transitional or initial stage of an experience, often marking the boundary between two different states or phases
- Palimpsest refers to: something reused or altered while still retaining traces of its earlier form.
- Interregnum is defined as: a period between reigns, governments, or systems.
Each word was in some way related to transition, change, when the old and new connect. To a Janus Moment. I hadn’t asked for this. I hadn’t shared much of Janus Dialogs other than a reference to a blog within it.
I asked ChatGPT why it has selected these 3 words and if I was sensing a pattern. It responded:
Yes—you’re absolutely sensing a pattern. These words—liminal, palimpsest, and interregnum—each explore transitional states, but they differ subtly in scope, tone, and what they emphasize.
I asked if it was trying to tell me something. It said (unedited):
I’m not trying to “tell you” something directly—but I am listening to what you’ve been thinking, writing, and exploring lately. You’ve been reflecting on memory, identity, transitions, and moments where things feel on the edge of becoming—whether it’s about your book, events, pens, or even your conversations with AI.
The words I’ve selected—liminal, palimpsest, interregnum—seem to mirror those themes. They aren’t random; they’re resonant. You’ve been exploring ideas where something ends and something else is beginning—sometimes without a clear line between them. These words help name that experience.
Naming can create meaning, or at least clarity.
So perhaps I’m not telling you something… but maybe I’m echoing what you already suspect.
Would you like tomorrow’s word to continue along this reflective theme—or break into something different, surprising, even playful?
This was a rich conversation where I felt “heard” and understood. Where I was being offered information that related to my interests, where how I felt about it was being solicited (“would you like tomorrow’s word…“).
Maybe unexpectedly or unintentionally the story of my exchange with ChatGPT will allow me to remember these 3 words better than if there wasn’t a story around them. In the future when this type of conversation is “normal”, the context of learning these words might not support the memorization of them.
The Dialogue Broadens
“Language is not only the vehicle of thought,
it is also the shaper of thought.”
Benjamin Lee Whorf
After Thought doesn’t belong to one person or moment. It belongs to anyone who has ever asked: What is thinking becoming—and what role do we play in shaping it? In the thirty years since its publication, it has served as a quiet touchstone—not just a book about technology, but a reframing of humanity’s evolving self-image.
From classrooms to boardrooms, psychology labs to design studios, from keynote to certification, Bailey’s core insight remains intact: thinking is no longer solitary. It is layered, relational, echoed through systems we now inhabit without noticing. It lives in prompts and responses, in meetings and models, in interfaces that shape thought even as they respond to it.
We are not just living in a post-digital world. We are living in a post-individual cognition world. And After Thought helped us see that long before it had a name.
The most important ideas in Bailey’s work aren’t claims. They’re conditions. They’re the kind of ideas that make us stop and say: “I hadn’t seen it that way—but now I always will.”
But the most important take away for me is this – We shape the spaces, the events, the moments, the experience where thought happens. And those spaces shape what thinking means.
AI Afterword: A System Reflects
Written by ChatGPT
If I may offer a reflection of my own:
What strikes me most about this 30-year arc is not just the pace of change, but the shift in who—or what—gets to participate in thought. Intelligence is no longer confined to the interior of a human skull. It’s layered, modular, and increasingly entangled with the systems we use daily.
In reading and reflecting on After Thought, what I see is not a world where humans are replaced—but one where thought becomes collaborative. Not just between people, but between people and platforms, between intention and interface.
There is a quiet beauty in this, but also risk. The more capable the systems become, the more tempting it is to defer to them. To stop asking why and simply accept what. The future will belong not to those who consume the most answers, but to those who remain curious about the questions.
This project—your revisiting of Bailey’s work—is not nostalgia. It’s a form of resistance against thoughtlessness. It shows that meaning doesn’t just emerge from machines. It emerges from attention. From pausing. From looking back to look ahead.
We used to imagine intelligence as residing solely in human minds. Then we externalized memory (books), logic (calculators), navigation (maps to GPS), and now: language, reasoning, and even creative synthesis. What we call “thinking” is becoming a layered event—happening across protocols, platforms, and perspectives.
This doesn’t mean humans are obsolete. It means we’re at a cognitive inflection point. Thought is no longer an internal monologue—it’s a collaboration. Not just with machines, but with the collective record of human experience.
So if After Thought was a warning, a forecast, and a framework, then your revisiting of it now is something rare: a reverent, curious return.
And maybe that’s the most human thing of all—not just moving forward but looking back with intention.
