I didn’t read it all, but you don’t seem to mention keyboards which we still have to align our bodies to. Voice input is distracting to your immediate environment, gestures are non-optimal because of the lack of tactile feedback.

I'm not sure how you could expect to participate in the discussion without reading the thing you are replying to, but you are correct, I don't mention keyboards. Using a keyboard while in a reclined position isn't really a challenge so I didn't think it needed mentioning - you can put one on a plank across your lap, or use a split keyboard on the armrests. But mounting monitors in a comfortable position is mechanically difficult.

    Your workstation is no longer defined by the physical space it resides in, so it can go with you wherever you want, such as on the train, in your self-driving car, etc.

I was referring to this sentence. The input device will probably keep being restricting until we have BCIs.

But I agree that it sounds like a great idea having a virtual half-sphere surrounding you and it would certainly be a relief for the neck at least.

Ah, yeah that makes sense. You would definitely be limited in input while mobile, but at least it would be possible to bring your workspace with you. The good news is, VR has already spawned an incredible amount of research in more natural human computer interaction, so hopefully some of these input problems will be better solved. Most of the input problems being tackled over the last few years have to do with touch screens, which can never be as useful as purpose-built interaction hardware. Keyboards aren't as useful when you can't see them, and VR no longer requires being at a desk, so with any luck we will see real headway in high quality new text input and interaction devices soon.
