Chapter Satire, Tool Use and War of 2001: A Space Odyssey - Study Guide by Arthur C. Clarke and Stanley Kubrick

And so it is with the Star- Child, despite millions of years of evolution and the intervention of an alien intelligence: "Then he waited, marshalling his thoughts and brooding over his still untested powers. For though he was master of the world, he was not quite sure what to do next. But he would think of something."
