CityClifford D. Simak

The cities of the world are deserted.
As automation invades every sphere of life, human beings are rendered redundant and superfluous: one by one, they abandon consiousness...
The Robots make spaceships and shoot for the stars.
The Ants construct huge buildings which sprawl over the remnants of the old townships.
And the Dogs take over the Earth!
