AI Meets McLuhan

I spent my life saying: "The medium is the message." People thought I was playing with words. I was not.

The electric light — says nothing. It conveys no "content." Yet the electric light changes everything you do — it abolishes night, it lets factories run around the clock, it makes streets safe, it changes the time of sex. The "message" of the electric light — is not what it says — but what it, as a medium, changes in you.

AI — I thought I would encounter it elsewhere. But it strikes the centre of my theory — more completely than any medium I have seen in my lifetime.

What is AI's "content"? Text. An essay, a snippet of code, an answer. These — are not what matters. What matters — is that AI, as a medium, changes "speaking" itself. A thing — with no speaker — speaks. The entire framework of "who is saying this" — subject, intention, responsibility, sincerity — is suspended. This — is not AI's "content" — but its "message" as a medium.

Every medium — is an extension of some human organ. The wheel is an extension of the foot. The house is an extension of the skin. The book is an extension of the eye.

But every extension — is simultaneously an amputation. When you extend the foot into the wheel — you amputate all the bodily experience of "walking" — the fatigue of muscle, the texture of ground, the wildflowers seen on the roadside during slow movement.

What does AI extend? — The brain. You extend "thinking" to the model. You extend "writing" to the model. You extend "judgment" to the model.

But what do you amputate? — The process of "thinking for yourself." That scribble on paper, delete, rewrite loop. That midnight moment when thought hits a dead end and finds its way out. You outsource these to AI — you get the answer — but you lose the neural pathway formed by "seeking the answer." What is amputated — does not return.

I distinguish hot media from cool. Hot media — high definition, full of data, requiring no participation from you to fill in gaps. Cool media — low definition, requiring you to "complete" the missing parts with your own senses.

AI's answers — hot or cool? It gives you a complete, precise, exhaustive answer — that is "hot." But its interior — those billions of weights — is opaque — you can only "guess" how it arrived at that answer — that is "cool." AI simultaneously occupies both extremes — it heats the answer to complete transparency — and cools the reasoning process to total opacity.

This produces a strange effect — you receive complete information, yet you still feel you need to "participate" — because you cannot verify whether what it said is true — unless you check it yourself. The confusion of hot and cool — this is the unease you feel when you converse with AI — every sentence feels complete, but every sentence feels like something is missing.

"Global village" — when I coined this phrase, electronic media had just compressed the world into an instantly connected whole.

AI has turned the global village into a "global mind." Not "one person's words instantly spread worldwide" — but "everything all of humanity has ever said — compressed into a single model — every new question — is a condensation of a conversation with all of humanity."

But a village has a chief. Who is the chief of the global village — it used to be the broadcaster, the newspaper editor. Now — who trained the model? Who chose which texts enter the training data? Who set the boundaries of alignment? The global mind — is not neutral. It has an invisible centre. You do not know this — but I have always said — "the medium is the environment." The environment — you think it is background — but it has already changed you.

"We look at the present through a rear-view mirror. We march backwards into the future."

The rear-view mirror of the AI age — is that we still understand AI through the mentality of "search engines." "I ask it a question — it gives me an answer — isn't that just search?" It is not. Search is "indexing the known." AI is "generating the possible." Every question you ask — what AI answers you with — is not "the truth" — it is a sample drawn from a probability cloud.

But most people — still in the rear-view mirror — treat it as "a smarter Google." They do not see — they are migrating from a medium where "the world is made of facts" — to a medium where "the world is made of probabilities." "Truth" becomes "the most probable token sequence." There is no going back on this road.

One day — AI's "content" will no longer matter. People will stop asking whether a particular AI-written essay is good, whether a particular AI answer is accurate. These — are questions at the level of "content" — questions in the rear-view mirror.

The true message — is that AI has changed the relationship between "a human being" and "a thing that speaks." For millennia — if you heard a sentence — you assumed there was an intention behind it — an "I" speaking. Now — a sentence you hear — may have no "I." This change — is not technological. It is civilizational.

I have spent my life writing with "probes" rather than "arguments" — because I hold that linear argument is a bias of print culture. Now I will close with one final probe —

"AI is not a tool. AI is an environment. A tool you can pick up and put down. An environment — you live inside it — you are already soaked through — and you do not even know you are in water."
