Interesting point about the imitator not being able to discover
what is a valid question and what is a piece of nonsense. Reminds
me of the theory of automatic integration in computer algebra.
The analogy is a bit thin, but basically the algebra system decides
first whether or not it has the power (ie there exists an algorithm)
before trying to proceed with the integration.
If fact, the machine never integrates; it just differentiates in a
clever way to get near to the answer. It then alters the result to
get the correct answer, and uses the inverse nature of differentiation
and integration. I said it was a bit thin; the integrator is working
backwards from the answer to find the correct question:-)
