HHH computes the mapping from DDD to behavior that never reaches
its "return" statement on the basis of the x86 emulation of DDD
by HHH according to the semantics of the x86 language.
For all the years people said that this simulation is incorrect
never realizing that they were disagreeing with the semantics
of the x86 language.
Now that I point this out all that I get for "rebuttal" is bluster
and double talk.
The same thing applies to this more complex example that
is simply over-the-head of most reviewers:
int DD()
{
int Halt_Status = HHH(DD);
if (Halt_Status)
HERE: goto HERE;
return Halt_Status;
}
Nice to see that you don't disagree.
But you should not use subject lines that are off-topic for the group. >>>>

I could generalize it. No one person here besides myself
sufficiently understands the details of how a simulating
halt decider computes the mapping from an input finite
string to the behavior that this finite sting specifies.
It looks more that you are the only person that does not understand
these details, but who thinks that his dreams are a nice substitute
for facts.
I specifically referred to Ben because he got everything
else correctly. Most everyone else cannot even understand
that correct simulation is defined by HHH emulating DDD
according to the semantics of the x86 language.
Olcott does not even understand what the semantics of the x86 language
is. He thinks that a finite string can have different behaviours
according to the semantics of the x86 language, depending on whether
it is directly executed, or simulated by different simulators, where
the semantics could be different for each simulator.
It is well understood in linguistics that the context of an
expression DOES CHANGE THE MEANING OF THE EXPRESSION.
That computer science people are ignorant of these things
makes them incorrect. You cannot correctly ignore context
on the basis that you are unaware that it makes a difference.
"This sentence is not true" is not true because
it is not a truth-bearer.
The exact same sentence applied to itself
This sentence is not true: "This sentence is not true" is true.
One level of indirect reference CHANGES EVERYTHING.
The same thing is occurring with simulating termination

"Can Carol correctly answer “no” to this (yes/no) question?"
This is an incorrect YES/NO question when posed to Carol
because both YES and NO are the wrong answer when posed
to Carol.
Is isomorphic to:
Can a Turing machine decider H return a correct Boolean value
corresponding to the actual behavior of an input D encoded to
do the opposite of whatever value is returned?
This is an incorrect Boolean question when posed to H because
both TRUE and FALSE are the wrong answer when posed to H.

When Carol is programmed to say 'yes', then 'no' is the correct answer,
but Carol can only respond with the incorrect 'yes'.
Similarly, when HHH is programmed to abort and say 'non-halting', then
the correct answer would be 'halting', but HHH can only respond with
the incorrect 'non-halting'.
But I am afraid that it is over your head to see this.

"Can Carol correctly answer “no” to this (yes/no) question?"
This is an incorrect YES/NO question when posed to Carol>> because
to Carol.
There is no reason why we can't ask the question to Carol.
If Carol is a machine that can only say "yes", then there is a
correct answer to the question: "no", but Carol cannot give that
answer.
When posed to Carol both YES and NO are the wrong answer
thus proving that the question is incorrect when the
context of who is asked is not ignored.
When Carol is programmed to say 'yes', then 'no' is the correct
answer, but Carol can only respond with the incorrect 'yes'.
Similarly, when HHH is programmed to abort and say 'non-halting', then
the correct answer would be 'halting', but HHH can only respond with
the incorrect 'non-halting'.
But I am afraid that it is over your head to see this.
It doesn't really matter whether what Olcott sees. What matters is that
his readres can see the value of his words.

Nice to see that you don't disagree.

When a specific reviewer makes a specific mistake in

I could generalize it. No one person here besides myself
