The Attention Chapter

Why the Scarce Resource Isn’t What You Think It Is

Here is something I noticed recently, talking to a friend. When she throws away food, she feels it. The plate is heavy. She can see the rice she didn’t eat, the half of a sandwich she let go cold. There is a whole human ritual around scraping a plate into a garbage can — the weight, the sound, the slight guilt. Food waste is embodied. You cannot pretend it didn’t happen, because there is literal, physical evidence in your hand.

Now think about what happens when you ask an AI a question you don’t really need to ask.

Nothing. The tokens stream. You glance at the answer. You close the tab. There is no weight, no sound, no scraping. The electricity was spent in a building five states away, by a chip you will never see, routed through wires and switches you cannot picture. The “waste,” if there was any, is completely invisible to you. There is no plate to scrape.

This is the first half of a really important asymmetry. Food waste is visible and embodied. Intelligence waste — if that’s even the right word — is not. Which means the feedback loop that makes humans frugal with food is, for computation, absent.

But here is where it gets interesting. Because the second half of the asymmetry cuts the other way, and once you see it, the whole argument about AI and attention looks different.

The Bottleneck Isn’t Supply

Stop for a second and think about how much information you can actually absorb in a day.

You have sixteen waking hours, give or take. You have two eyes that can track one thing at a time. You have two ears, and while you can hear several things at once, you can only really parse one voice at a time. Your working memory holds maybe seven items, plus or minus two. Your reading speed tops out somewhere around 300 words per minute, and that’s if you’re actually comprehending rather than just scanning. By 10 PM you are tired, and by midnight you are basically useless.

In a full day of intense effort, you might genuinely, deeply absorb — the kind of absorbing where you could explain it to someone else a week later — maybe 20,000 to 30,000 words of new, substantive content. Call it the length of a short book, or a long article, or a serious conversation.

That’s your ceiling. That’s how much intelligence, in the form of ideas and information, you can actually consume per day, no matter how much is available.

And here is the thing: you are already saturated. Before AI existed, you were already getting more information than you could absorb — from school, from books, from the internet, from people talking to you, from videos, from your phone. The bottleneck in your life is not the supply of intelligence. The bottleneck is you.

This is important, because it means the economics of intelligence are very different from the economics of food.

Food has diminishing returns to the eater. One sandwich: hungry no more. Two sandwiches: full. Three: sick. Four: actively harmful. This is why personal frugality with food is self-enforcing — your body tells you to stop. Waste comes from producing too much, not from consuming too much.

Intelligence works the opposite way. Supply can be essentially infinite and cheap. But your capacity to receive is fixed, and already fully spoken for. What changes when more intelligence becomes available is not how much you consume — that number is roughly constant — but what you consume instead of what you used to consume.
