“caches like Hubble[1] and Constellation[2] (which let you query the entire network in one request)”

I think that’s a part of it but doesn’t state it fully. AT doesn’t just give consistency, but a shared data model across apps. So apps can reference and render content from other apps. It’s really kind of like a web of typed JSON. Different apps are lenses through which you can see the same network. Anyone can build new experiences on top of old data. There’s nothing remotely equivalent in AP. AP couples data to apps
