# Layers of Reality

*First noted: June 2026 · Last revised: October 2026*

The invisible overlay described in the previous chapter can become visible. That is where augmented reality finally finds its use.

AR is usually discussed on its own, as if the question were whether people will wear glasses to look at floating icons. That is the wrong question. The interesting one is what happens when a world already full of situated agents gets a screen in front of the eyes. At that point AR is no longer a gadget. It becomes the interface of the agentic world around you, and situated agents may be the use case it has been missing all along.

> Camera-and-voice glasses are real and selling in volume. IDC projects around 13.6 million display-less AI glasses for 2026 at an average price near $376, after a first quarter that shipped 2.25 million units, up 167% year on year. EssilorLuxottica reported more than tripling sales of the Meta AI line in 2025.

> Glasses with a display are real too, and far more modest than the phrase "augmented reality" suggests. The Meta Ray-Ban Display, released at $799, puts a 600 × 600 screen with a 20-degree field of view in front of the right eye only. It shows messages, a camera viewfinder, live captions, translation, and turn-by-turn navigation in a handful of cities. It is a heads-up screen rather than a world-locked overlay: the content sits in your field of vision, it is not anchored to the building you are looking at. Glasses with any kind of display are forecast at roughly 3 million units this year, against 13.6 million without one.

> So the hardware is arriving faster than expected, and the layer is not arriving at all. No place exposes a callable presence, no registry establishes which agent legitimately speaks for a square, and no permission system governs who may annotate shared space. The surface is showing up before the layer it is supposed to display.

### Composable reality

There will probably not be one layer but many: official ones, approved by whoever controls the default, and alternative layers alongside them.

Imagine an application, almost a social network, running on your AR glasses, where individuals and organisations can bind a presence to a place or an area for a given time, and where you subscribe to the feeds of reality you want to see. One layer would be official: recognised actors register or rent a presence there to offer their services. 
The others would be community layers, visible only if you follow the people, institutions or groups behind them: a local history society annotating old facades, a cycling club flagging dangerous crossings, friends leaving each other notes around the neighbourhood.

### Visible power

The moment overlays become visible, power becomes visible with them. Who decides what appears first? What is public-interest guidance, and what is advertising disguised as help? What stays on screen, and what only appears when you ask? And who is allowed to annotate shared space at all?

Nobody owns these questions today, which is normal since the thing they apply to does not exist yet. If nothing changes, they will be settled the way these things usually are: as default settings in whichever products ship first.

And that is the likely outcome. Unless an open alternative exists, the overlay will be controlled by the brands we already use. Google, Meta, Samsung: each will serve its own world overlay, through its glasses, its phones, its maps. What you see in the street will be what your platform decided to show you. Reality will still be composable, but inside one catalogue.

That is why AR should not be treated as a nice add-on to the agentic future. If it matures, it is where mediation, trust and power over a territory stop being abstract and become something you can see, standing in a street.
