Don't get me wrong, I'm not volunteering but eventually it will be safe.
Theres definitely barriers to overcome but to go with your analogy, I drive a car everyday on the highway even though a malfunction or even just an other user being stupid can easily lead to my death. That's just to get to work or see friends. I could imagine myself braving worse to get to use full dive vr.
But you couldn't pay me to get into one of those death traps when cars were first invented though. I'm eager but I will definitely wait a while before jumping in.
It can eventually help disabled people move, see, hear and talk.
For everyday people, this will replace phones and computers completely. We will be able to project a private screen on any surface, even mid air. We will be thinking the words instead of saying them during phonecalls.
Movies and games are going to be so immersive it's probably going to cause some serious societal issues. Larping is going to become big I'm guessing.
That's just the surface stuff that's easy to think of. It gets even nuttier if you think about recording and downloading dreams and memories, some of the really sci Fi stuff. The possibilities are literally endless. Obviously though, there's a way to go, it's still in its infancy.
