     Disagree.  There is a clear advantage in distinguishing those

That is not a disagreement.

Then show how two statements about distinct topics can disagree.

        You've had the free, introductory five-minute argument;  the
half-hour argument has to be paid for. [:-)]

        [Perhaps more helpfully, "distinct" is your invention.  One same
statement can be either true or false, a mistake or a lie, depending on
the context (time. place and motivation) within which it is uttered.
Plenty of examples both in everyday life and in science, inc maths.  Eg,
"It's raining!", "The angles of a triangle sum to 180 degrees.", "The
Sun goes round the Earth.".  Each of those is true in some contexts, false
and a mistake in others, false and a lie in yet others.  English has clear
distinctions between these, which it is useful to maintain;  it is not
useful to describe them as "lies" in the absence of any context, eg when
the statement has not yet been uttered.]

There is another sense in which something could be a lie.  If, for
example, I emphatically asserted some view about the minutiae of medical
surgery, in opposition to the standard view accepted by practicing
surgeons, no matter how sincere I might be in that belief, I would be
lying.  Lying by ignorance.

That is a lie unless you qualify your statement with X is a
lie(unintentional false statement). It is more truthful to
say that statement X is rejected as untrue by a consensus of
medical opinion.

No, as so often, you've missed the nuances.  The essence of the scenario
is making emphatic statements in a topic which requires expertise, but
that expertise is missing.  Such as me laying down the law about surgery
or you doing the same in mathematical logic.

This allows for the possibility that the consensus is not
infallible. No one here allows for the possibility that the
current received view is not infallible. Textbooks on the
theory of computation are NOT the INFALLIBLE word of God.

Gods have got nothing to do with it.  2 + 2 = 4, the fact that the world
is a ball, not flat, Gödel's theorem, and the halting problem, have all
been demonstrated beyond any doubt whatsoever.

Peter Olcott is likewise ignorant about mathematical logic.  So in
that sense, the false things he continually asserts _are_ lies.

*It is not at all that I am ignorant of mathematical logic* It is that
I am not a mindless robot that is programmed by textbook opinions.

You are a mindless robot that hasn't even mastered the basic textbooks.
What is in these textbooks is not opinions, but proven facts.  That is
something which is beyond your understanding - the idea that facts are
facts, and not opinions.
