And then there is the problem of you brain can think about things that aren't actually done, yet. Computers can certainly help in this regard, but they are more about sharing something that was done in a different way. Consider walking through a house. Sure, a computer can let you walk through one that hasn't been built physically, yet. I'd wager skilled architects can imagine walking through one that hasn't even been built virtually yet.
And, finally, there is the problem of thinking about data structures that are literally gigabytes in size. I have a hard enough time thinking about ones that are megabytes in size. I'm not entirely sure accurately visualizing large instances would really even help.
once you're familiar with your dev environment, you don't need to have it floating around in VR space. Its all memorized pretty much, instant access, L1 cache. so to look at something in VR you turn your head and the view pans. To look at it in your brain, its just there, instant lookup.
one requires a transition in space to access information (flying) the other does not (teleportation)
It's not, didn't you watch the video? You don't fly, you sit still. Even if you would want to move your virtual presence, I'll guarantee you that the computer can teleport you faster than your brain can, not that I think that would be comfortable..
Anyway, I'm glad that you're happy, so by all means stay happy.
