Your problem is you keep on ILEGALLY changing the input in your
argument because you have misdefined what the input is.
The input to HHH is ALL of the memory that it would be accessed in
a correct simulation of DDD, which includes all the codd of HHH,
and thus, if you change HHH you get a different input.
If you want to try to claim the input is just the bytes of the
function DDD proper then you are just admitting that you are
nothing more than a lying idiot that doesn't understand the
problem,

Turing machines only operate on finite strings they do not operate
on other Turing machines *dumbo*

That's right. But the finite string can be a description of a Turing

No that is wrong. The finite string must encode a Turing machine.

Same difference.

Not at all. The huge mistake of all these years is that people stupidly
expected that HHH to report on the behavior of its own executing Turing
machine. The theory of computation forbids that.

Encoding = description.
HHH isn't executed by anything.

// HHH is not allowed to report on this DDD
int main() { DDD(); } invokes HHH(DDD);

It simply reports on a string that
represents itself.
 

That way a Turing machine can say someting about another Turing
machine,

Not exactly. It can only report on the behavior that the input finite
string specifies.

Which is that other TM.

Do you agree?
 

even simulate its complete execution. Or it can count something
simple like the number of states or the set of symbols that the
described Turing machine may write but not erase. But there are
questions that no Turing machine can answer from a description of
another Turing machine.

All of the questions that a TM cannot answer are logical
impossibilities

Not true. Some interesting questions are undecidable.

It is a despicable lie that it even be called "undecidable". It is like
no one can "make up their mind" about the square root of a dead rat.

You may dislike the term; it means there is no program that gives
the answer for every input.
 

The term "undecidable input" incorrectly cites the decider
as the source of the issue instead of rejecting incorrect input.
The problem is that no program gives the answer
whether a self-contradictory input is true or false
because the correct answer is neither. It isn't
that the decider "couldn't make up ts mind" it is
that the input was invalid.
