> There will be some cool/scary stuff coming. Yes. For AR to work properly, it requires precise location. Apple, Lyft, FB et al are all using visual mapping. Where pictures are processed, rebuilt in 3d and key points extracted. Those key points can be compared to key points found in a sample image, using some trigonometry you can position that image in 3d (lat, lon, height and angle, so left right relative to north, plus up down and rotation) This mapping is accurate to about 20cm now (in real time) This means that (future) AR headsets know exactly where you are at all times. Combined with the tech to find where you left your keys (object recognition on steroids) you can find out who owns what pretty quickly, through the use of a dodgy app. Then there it the stalking. Facial recognition might be built in, so you can remember peoples names better (I suspect there will be at least a cursory attempt at permissions) but if a third party app has access to both position and the raw camera, you know the position of 80% of people within range of the glasses. AR glasses means that open source will have to confront ethics properly for the first time. You can have an open platform, but it will be the cause of oppression(because some prick will make a woman stalking app, its almost a certainty now.).
