"The kids are playing, better record a spacial moment" was one of the most dystopic things I've seen in a long time. Same with the ad at the end, with the father wearing it around his kids. I feel like the interface demands strapping something this futuristic over your head is just... wrong. Perhaps a few years of refining the tech can lead to something that feels more natural
It's only with the advent of proper video recording tech in a cell phone that this technology has gotten so small that it's (mostly) unobtrusive and since everyone has one on them all the time, it's not surprising when someone pulls it out and starts recording.
And many a larger family event usually has one (or more) family members dedicated to capturing on film / camera anyway, so what difference would it make what tech they were using to do it?
If this thing caught on, it would be no different from any of those others, with the two possible exceptions of
A) actually being more present for the recorder, as opposed to looking through a view finder wobbling in their hands, it's just whatever they're looking at through this thing already attached to their head. Additionally for child events, they could still be actively involved with both hands (as opposed to one or none with other camera equipment and trying to work through a view finder.
B) Being less obtrusive to the rest of the people. Sure, people "should" just enjoy the moment, but I'd rather be at a concert with a few thousand people using these to record their moment than a few thousand people holding their cellphones up trying to record it around everyone else's hands.
Another thing to consider are cases where this is used by people who are already professionally recording stuff. Sure, your wedding photographer you probably still want using a real quality camera setup, but would anyone be salty about the photographer's assistant going around and capturing 3d video and pictures of your wedding with this thing? I doubt it.
