I think this is more of a novelty/proof-of-concept rather than offering any serious use case. It does show a lot of potential for this kind of thing. If the form-factor can be refined into something less stupid looking, there could be more appeal in this tech to the general public than there was in 2013. There seems to be more of a collective shrug towards cameras and microphones in public than there was 10 years ago.
