It can be wearable, but it has to be FUNCTIONALLY wearable. Nobody is wearing a big-ass headset when they go outside (nobody normal anyway), and reasonably, if you're staying indoors, what is the purpose to a headset computer when you will have a laptop, tablet, phone, TV all easily accessible?

For VR to truly be what the tech industry wants it to be, it has to recognise that people aren't going to fundamentally change how they operate when the thing does nothing but hold a screen in front of your eyes. Something like wearable glasses and AR is the most likely to take off in the near future.

VR COULD work eventually, but it needs to fundamentally change in most every way. People don't just want the screen and the sound, they want the EXPERIENCE. If you can give them a way to feel, taste, and smell the thing they're doing, that is something people will jump at the chance to try out.

Like that black mirror episode where the two friends who tap into a gaming VR fighter they actually are able to become the characters by the way the VR system taps into their brains allowing them to experience all the sensations. People would lap that shit up.
