But many intelligent people have a sort of bug: they think intelligence is an end in itself. They have one idea in mind: to be intelligent, which is really stupid. And when intelligence takes itself for its own goal, it operates very strangely: the proof that it exists is not to be found in the ingenuity or simplicity of what it produces, but in how obscurely it is expressed.
