Technological advancements have a funny way of producing important side-benefits.

A change as massive as VR - we simply don't know how big a deal it is.

For example, as one of the smaller potential side-effects, imagine VR became good enough that there was no practical reason to have people travel for face-to-face meetings. That would have a significant knock-on effect (closing on single-digit percentile worldwide) on carbon emissions, global warming, and potentially catastrophic climate change.

Teleconferencing is currently very possible, including video to video or voice to voice, but this hasn't stopped people travelling around. I am not so sure that VR will suddenly be the thing to take off in this regard; if people aren't happy sat in front of a camera for a meeting, will they be happy wearing a headset?
