Well, I don't wanna be at that situation, cause it's gonna be too late to turn back... Its technical requirements have already been matured, tested and setup. The transatlantic data cables as well as those dedicated satellite uplinks are far more than enough to transmit any type of image on the fly. No one can even feel that those scan images were read by someone else on the other side of the world if someone signs them here.
I am also aware of that it's been a while they're testing "remote surgery" in robotic surgery rooms. Crazy, isn't it? However, I guess, nobody will admit to be examined or cut by a virtual doctor. So, it might not be stretched to the point to make things "cheaper" by private insurance companies.
Keep out of "virtuality" to secure your job, or don't come to me later crying (take it as a computer engineer + scientist's humble comments on that subject matter, and welcome the future from now, before late)
