Those use cases already exist to an extent with current products. I use google translate every day on the jobsite, google maps already provides step by step navigation, youtube videos guide me on car repair, smart sensors with phone and smartwatch alerts for almost anything you can imagine, rollable and thin film transparent displays for walls and windows. Its hard to see AR/VR overtaking existing technologies except for niche use cases. The tech is gonna have to advance well past 2030 projections to be both cheap and feasible for practical use. Batteries will need an order of magnitude higher energy density and microchips will need to pass the teraFLOP barrier while consuming less than a watt of power, all while fitting into a comfortable and unobtrusive form factor suited for long term daily use. I don't see that happening anytime in the next decade honestly.
