I was talking about the danger of predicting success of some technology based on personal bias, not about similarity between a VR headset and a mobile phone.

Duh.

If you have a VR headset, you may as well get a comfy reclining chair too. Or lie down on your bed/couch -- either way, your head can be supported by things that are not your neck muscles.

But how do you type in that position? Or were you not planning to type anything?
