We've demoed the HoloLens to hundreds of people and I find this the case alot, that is, until they put it on themselves and understand/experience what's going on. MR/AR is one of the hardest things to explain and understand until you have experienced it yourself but once people put the HoloLens on, it takes only a minute or two until it becomes second nature whether they are 6 or 60. There's just something natural about the whole experience.
