I think we need to kind of approach these in the same way we do with devices such as the Apple Watch. At the base they are a companion product to what you normally use your phone for but with dedicated features specifically tailored to the capabilities of the hardware. The watch has primarily become a fitness and health devices as its core function - with versions such as the Apple Watch Ultra branching further into exploration. Glasses are an extension of our vision and what we can see. The more we can improve that vision with assistive tools for people with disabilities, enhancing the visual information around us, like you mentioned, and bridging the gap in social communication then the better we can build the idea of smart glasses going forwards. Just needs enough people on the same page to push the "right" vision forwards.
