I'll take your argument a bit further. The thing is -- "human-data" interfaces are not particularly important. Human-Human ones are. This is probably why it's going to be difficult, if not impossible, to beat the smartphone; VR or whatever doesn't fundamentally "bring people closer together" in a way the smartphone nearly absolutely did.
VR may not, but social interaction with AR might be more palatable and better UX than social interaction while constantly looking down at at a computer we still call a "phone" for some reason.
