I’m not an expert on VR, but it seems to me that the consensus is that AR will truly mature after VR. So maybe it doesn’t make sense to differentiate, because at that point AR will be “VR-lite” rather than VR evolving as “AR-heavy”.
My personal opinion is that full immersive VR will be more compelling, as it’s going to all be about people interacting and collaborating over distance, and VR will work better for that.
