It can be used for these things but is it really an improvement ?
> real estate
How often do you do that ? Once every few years ? Aren't regular 3d models / regular virtual visits enough ?
> porn
Tried it, extremely awkward at best
> psychology
?
> situational training (firemen)
You can train in your Vive for 5 years straight, nothing will prepare you to the real deal. Just like playing a racing video game doesn't make you a racer.
> scientific visualization and collaboration
It's neat but does it change anything fundamentally ?
> social interaction
Nothing will replace real world interactions, be it facebook or VR it's all a gimmicky at best
> movie shots planning
?
Sounds like a solution looking for a problem. VR isn't new at all and besides gaming it really didn't pick up speed in any other industry. If anything AR could be a "revolution", if miniaturised enough (contact lenses size).
I received a free HTC vive after participating to a conference in 2016, used it a month and it's in a drawer since then. None of what the speakers were promising happened, VR is still the thing you get out once every 6 months to show it to a friend, the wow factor lasts 30 mins.
