The Invisible Trillion · The Attention Chapter

The Environmental Connection

Now, finally, the loop back to where this book started.

The reader who started this book was worried about data centers and the planet. That worry is real and legitimate, and the earlier chapters laid out the actual numbers.

But I want to say something that probably wouldn’t have made sense in the energy chapter. Most of what is environmentally wrong with AI isn’t the AI. It’s the attention economy it’s plugged into.

The biggest use of data centers, by a wide margin, is not AI. It is streaming video, social media feeds, and advertising technology. TikTok, Instagram, YouTube, and the ad-tech that follows you around the internet use vastly more data-center energy than every AI chatbot combined, and they do it in a way specifically designed to use as much of your attention as possible.

The algorithm that served you the upsetting video about data centers using too much water was itself hosted on a data center. The ads that interrupted the video were served by a data center. The app that notified you about the video was running on a data center. The comments you scrolled through were stored in a data center. The hours of your life that the app extracted — those were extracted using a lot of electricity, and they were extracted from you, which is the only non-replenishable resource in the whole system.

If you actually wanted to reduce the environmental impact of your personal computing, the single highest-leverage thing you could do is not to stop using AI. It is to use less social media. A day of intensive AI use, even for a power user, might involve 50 queries and a few hundred Wh of data-center energy. A day of scrolling short-form video involves closer to 50,000 Wh of streamed content served by data centers, plus all the ad infrastructure, plus the manufacturing amortization of the device you’re doing it on.

But nobody is going to tell you to stop scrolling, because the feed is what you use to be told things.

This is not a moralizing speech about social media — there are enough of those, and you have probably tuned them all out. This is an observation about where the energy actually goes, and where the attention actually goes, and why the two are related.

You are not being asked to care about data-center energy because data centers are the biggest environmental problem. (They are not. Cars, buildings, agriculture, and industrial heat are all vastly bigger.) You are being asked to care about data-center energy because caring about data-center energy feels actionable, and caring about industrial heat processes does not. Someone has gotten you to worry about the thing that’s most visibly tech-shaped, which is probably not the thing that would most matter if you fixed it.

This is also true of the relationship between you and your attention. The apps that extract your attention do so because your attention is the product they sell to advertisers. The electricity cost of running the app is a rounding error in that business model. The cost you pay, in hours of your life and in the shape of your own thinking, is not a rounding error. It is the entire point.
