VR lends itself more to MMORPG-like experiences, which are quite social. Similarly, Ready Player One didn't lack social interaction or real friendship.
For time spent in nature or making physical things it's probably the other way around. AR could make these things much more accessible (even if "less pure"), while VR doesn't exactly promote them.
Until we can perfectly simulate physical reality, virtual interactions will never be as real as real world interactions.
I'm not quite sure what makes an interaction more or less "real". The people on both ends of the interaction are real, so surely if they interact that is a real interaction?
So far all virtual interactions lack some aspect of communication, but with full-body tracking and eye-tracking VR already offers the closest analog to face-to-face communication we have. Mapping all the tiny facial expressions will remain a challenge, but isn't really that far fetched.
