For me, I think the killer app would have to be something that interacts with the real world. Watching movies, FaceTime, or browsing the internet won’t be enough for me to ever buy this. But maybe if there was something like a home repair or car repair app that could in real time identify and inspect the objects, give me visual and audio instructions on how to perform the repair, that could be a killer app. But I’m not sure the AI/ML side is good enough yet to enable that.
