This is why companies are trying to break into it. Hardware is the main gap at the moment but Apple is the best hardware manufacturer in the world. The M chips are a step in this direction (high performance, low power).
I imagine you will still use the internet in AR, otherwise how will you get information? What you probably meant is a web browser on desktops and phones.
100% but Apple always follows others leads and then makes a better product. Right now AR/VR leans heavily into gaming as for the audience is already built in. AR has so many applications I think eventually it will destroy the VR market usability wise. Im just saying for Apple it stands a better chance than their car efforts.
In the case of VR/AR, we know Apple has been working on VR products since at least the early 90s but those never made it very far other than a few things like QuickTime VR. As we can see from the rest of the field it was only until the last half-decade that people were getting things like the visual quality or especially latency to acceptable levels and battery life / weight still seem to be a substantial problem.
If you look at the numbers for VRChat it shows there is a market outside gaming.
