As others have mentioned there must be better uses but to me it seems like sensationalism that boils down to this if you weren't there: I can livestream something from (essentially) a helmet cam to a platform that not many people actually use.

I know I'm being cynical but I struggle to come up to a practical use where the technology does not already exist (thinking surgery, military, etc.) so my only assumption is they can compete on price or I'm just missing something and getting old.
