AR diminishes reality

Does really marker-based AR augment reality?

The essence of VR is virtual, and the essence of AR is real.
The marker-based AR almost hides real, and shows CG on the marker.
It seems that the main object of the view is virtual one, rather than real one. Marker-based AR makes real just stage effect or background.

That's main reason why AR application doesn't become useful tool, although the interface and/or experience has big impact first time.

Any marker/barcode is not real for human because we cannot get it at all.

Do you really believe that 3-D presence is better than 2-D's to show some information?
Why is still web 2-D?
