When I think about who would have the time and motivation to sit in a VR world all day long I can not imagine girls or a lot of adults of some type.
I really struggle seeing anyone outside of a private space wearing it in public, in an office or public transport. It looks weird. It removes you from reality and your surroundings.
So who is left? Boys? Already single man motivation for playing the same games all day long like egoshooters etc.
Porn will be a motivation for sure.
