Outside of gaming and industry use AR/VR have felt a little like a solution in search of a problem. I do believe though that the people who work at Apple are capable of solving that problem, finding the use cases that an every day person wants it for.
This is my feeling too - I just don't see an immediate usecase for such a device outside of a select few niches, none of which (even combined) move the sales needle for a company of Apple's size. What are people actually going to use this for? I just don't see it - although there could be something as the tech matures in a few years.
