When I write in my blog I am in my space. When I talk in, for example, Facebook, I am in that space.
I have said for years that the next big thing will be when you and I can be each in our own spaces and yet converse.
So I read Tim Cook's observation with interest:
Augmented Reality gives the capability for both of us to sit and be very present, talking to each other, but also have other things — visually — for both of us to see. Maybe it's something we're talking about, maybe it's someone else here who's not here present but who can be made to appear to be present.
