Let's be realistic. AR will never be a thing until you can do it without some clunky device.
MAYBE someone will whip out their phone to do something with AR in a store once in a while, but that will be a small subset.
AR/VR is NOT going mainstream until the device is small. I'm talking super thin, lightweight glasses, or let's get super sci-fi here, something like contact lenses that basically give you an AR overlay on your vision at all times. Otherwise, the idea of big ol VR/AR goggles becoming mainstream is a pipe dream. It will remain niche at best until the form factor shrinks considerably.
I would MAYBE wear AR glasses out and about if they just looked like sun glasses. Anything more unusual than that, and I'm out, and so are probably 99% of the population.
I've been super curious about the rumored AR/VR goggles from Apple, but mostly because if they are actually "Goggles", they have likely already lost the battle. However, if they are something that look really good and are convenient to take on and off, and don't look stupid, then I'm not worried about the applications, because the apps will come. But, like I said, AR/VR is never going to work if it's not a form factor you can just wear like glasses, no different than your apple watch is just wearing a watch.
Apple watch is actually a good example, because if the first apple watch looked like you were strapping some big computer to your wrist, it would have failed immediately. No, it looks like a really nice, fancy watch. Same thing with VR/AR. If it looks like a really nice, designer pair of glasses, then it's a win. If not, this is DOA.
