If electronic picture making was the only thing known most folks could not care less; except at APUG it seems!
Sean is right. There is something unique and special happening when something that was part of the subject leaves it, travels across space, goes through a lens, and makes a picture of itself on an actual sensitive physical surface.
That this happens directly and only from the energy donated by the subject matter and without anything entering and re-emerging from cyberspace is sublimely wonderful.
If photography had never been invented we would have to invent it.
