Lol, the only grapes here are your sour grapes that people don't give a fuck about VR except for shiny toys and things that run up medical bills for equipment surgeons don't need, making healthcare costs worse.
Also don't make me laugh about the F-35. Look up "Boondoggle". As for professional uses, drone operators are about your only successful use case. Everything else is just an expensive toy looking for a purpose.
You wouldn't be so salty if you weren't insulted that VR is a ridiculous joke.
