'A vast circle of scarlet stars came up into the greenish desert dusk.'
'He had constructed an organ, a brain, of metal, entirely inorganic and lifeless...'
'I shall never forget the sight... when the yellow gleam of the precious metal appeared under the star dust.'
Oh, and now I suppose someone will develop the robotic porch pirate.
'This thing will start at one end of ...a house and build it complete to the other end, following drawings only.'
'In contrast to the airless desolation outside, the interior of this five-acre greenhouse was the one most desirable place to be.'
'It was cheaper to pay the refugees to go without up-to-the-minute equipment.'
'Evidently they have never had a planet of their own...'
