OK, then, give the page and line numbers from Turing's 1936 paper where
this alleged mistake was made. I would be surprised indeed if you'd even
looked at Turing's paper, far less understood it. Yet you're ready to
denigrate his work.

"do the opposite" code is unreachable.

Can Carol correctly answer “no” to this (yes/no) question?Which shows you don't know the difference between a willful being and a fully determined program.

When the context of who is asked is understoodBut the question has nothing to do with who it is asked to.
to be an aspect of the full meaning of the question
then the question posed to Carol is incorrect because
both yes and no are the wrong answer.
Credit to Richard Damon for finding the loopholeNo, the real problem is a question about the future behavior of a willful being is just not a valid objective question. It doesn't HAVE a correct answer until the event happens, thus it isn't a question of fact, but of true guessing.
in the original question:
Can Carol correctly answer “no” to this question?
With the original version Carol can shake her head
to indicate "no" without actually saying "no".
