The Overexposed City; The Ghostly Landscape

Barriers and boundaries within cities now define them. Screen interfacing is now 'visibility without confrontation', a depth of field now exists erasing the face to face city scape, mutes the conversation within the city and takes it further from reality.
Cities run into cities and nothing is far away anymore, everything becomes overexposed. We no longer enter a city through a 'ceremonial gate' or 'triumphal arch' but through 'technological space- time' where all time is warped; day is night and nigh is when there is no longer communication, so does it ever come?
So how do we organize our cities? Where is the place of urban architecture? What becomes the function of it, can we still design for cities while we are absorbed within this sub- reality, this technological space- time? Does architecture still have a place in our society or is it fizzling out? Will it still contain a purity of line, the complexity of being made with two hands and the authenticity of being created with pencil and ink? Have we abandon our cities and left only a 'ghostly landscape'? The 'fossil of past societies'? Or better yet, have we abandoned our architecture, have we sold it for flashy 3D models and computer graphics? Can we fix this or are we destined to destroy our cities for the existence of this sub- reality?
