Allowing you to "do AR" is very different than having AR that even 10% of the planet can use without vomiting. Nobody is actually going to actually use the quest for AR. It's not remotely close to the bare minimum to actually function. People who try for more than 10 seconds at a time will vomit. Repeatedly.
And that's before the fact that it doesn't have the resolution for text, nullifying almost all of the utility the Vision Pro has.
