I've seen legit-useful AR apps for doctors/surgeons, dentists, firefighters, law enforcement, warehouse workers, etc. Basically anything where you need to be out in the real world doing something that would benefit from having situational-awareness of other non-visual conditions. This is a pretty wide swath of professions, with a lot of potential to save lives. Just having a patient's vital signs projected while a surgeon operates could prevent many deaths on the operating table, along with lots of fuck-ups like leaving a scalpel behind in the patient.
But in reality it’s splitting hairs. Similar to discussing which tone pot values are better for your Stratocaster. Most people just don’t care, nor should they! “Stop trying to make fetch happen” as they say.
what really worries me would be AR ads
