You can't see a use of a VR headset outside of games..? Seriously..?
Training for surgeons, pilots, armed forces, referees and umpires in sports, astronauts, divers...the list goes on and on.
Uses in the classroom for kids at schools and universities.
And entertainment - porn, video games, films, sporting events.
Its use in porn alone is going to be worth a ridiculous amount of money, It's what made VHS a success over the far superior Betamax format.
