I will reply to this part. I cannot know how Copeland has managed
to misread Turing's paper. However, it should also be fairly obvious
that humans do not have the role of oracles in the debugging process.
On the other hand, they do every non-trivial transformation in this process. At
any rate, if they had the role of oracles, they would _be_ oracles, but
most obviously they are not because the halting problem has infinite
information content, i.e. a finite brain cannot solve it. If, on the other
hand, you are one of the people who think they can solve the halting
problem, I challenge you to solve the twin primes conjecture with the
magical one second look.
