I’m very suspicious of using logical results such as Penrose's use of Goedel’s
Incompleteness Theorem (GIT) to limit the possibility of strong AI machines.
I’m not even comfortable with going the other direction, employing the Heisenberg
Uncertainty Principle as a physical basis supporting/establishing GIT. It is far
too easy to commit a category error, projecting properties manifest at one level
into another categorical level, which may or may not evidence such properties.
At least one definition of emergence has no trace, no predictability whatsoever.

"However, it seems to me that Conway and Kochen go on to make some bad
interpretations of what this theorem says about freedom, determinism, and
interpretations of quantum mechanics. They say, “our theorem asserts that if
experimenters have a certain freedom, then particles have exactly the same
kind of freedom.” This is true for a very specific type of freedom (namely,
non-supervenience on the past) but their theorem says nothing else about any
other kind of freedom, or whether their freedom has anything to do with the
kind of freedom that matters. It may be that this kind of freedom is an
important component of free will in the ordinary sense, but it may be that
free will essentially requires not just non-supervenience, but also some sort
of complex structure that just isn’t possible for the motions of individual
particles."

SH: I think the last sentence in the above paragraph is another way of stating
that the emergent properties at a more complex level are not predictable from
the more primitive level(s), or conversely, that the more complex level has
the same properties carried into it from/(contained in) the less organized level.

Taken from Conway's paper:
"It asserts, roughly, that if indeed we humans have free will, then
elementary particles already have their own small share of
this valuable commodity. ...
Some readers may object to our use of the term "free will"
to describe the indeterminism of particle responses. Our provocative
ascription of free will to elementary particles is deliberate, since
our theorem asserts that if experimenters have a certain freedom,
then particles have exactly the same kind of freedom. Indeed,
it is natural to suppose that this latter freedom is the ultimate
explanation of our own."

SH: This approach reminds me of animism, [from the Wiki]
"Hylozoism is the philosophical conjecture that all or some material
things possess life, or that all life is inseparable from matter." or
I think more accurately, "Panpsychism, in philosophy, is either the view
that all parts of matter involve mind, or the more holistic view that
the whole universe is an organism that possesses a mind (see pandeism
and panentheism). It is thus a stronger and more ambitious view than
animism or hylozoism, which holds only that all things are alive."

SH: Without nitpicking too much over definitions, let's assume
(before Conway) that free will belongs to living things, especially
mammals; they have consciousness generated by a brain which
exhibits a mind. Humans as well as lemmings are also assumed to
have instincts as well as the assumed free will.

How is Conway going to separate the free willy aspects of his elementary
particles from the other properties or characteristics which imbue the
decision making process of a mind? I mean that I don't think that Conway
can make a reasonable argument which says the source of free will originates
in elementary particles but not other aspects of brain generated consciousness
such as instincts. Or another way to put it is how is only the free will
property isolated and transmitted to the more complexly organized choice-making
mind, but that the other properties besides choice-making that the mind exhibits
(other than) ->= free will, how are they isolated and excluded from being
transmitted as trace manifestations of properties (why only and exactly free will)?

Humans have consciousness which is necessary to support free will. What is
the explanation that if humans have free will as an aspect of consciousness,
ultimately derived from freedom of the elementary particles source, why are
not elementary particles also the ultimate source of other aspects of (human)
consciousness. Why would humans acquire only the free will property from
elementary particles source and not the other properties of consciousness?

What I'm getting at is that if elementary particles are the source of human
free will, and free will requires a living brain to generate consciousness and
the mind which renders decisions, then the elementary particles also require
the same necessary and analogous properties at their own level of complexity.
I think it would be a category error to assert that some entity at a primal
level which has free will doesn't also need a mind or consciousness mechanism
(even if just remotely analogous to human mind) in order to generate such a choice.

I don't think Conway can talk about this situation in isolation from the
structure needed (which he attempts to do) that entails free-will at the
macrocosmic level. If there is a structure for free will at the macrocosmic
level, then there also needs to be a corresponding foundational structure
at the microcosmic level. Basically, that will require attributing primitive
consciousness/awareness in the foundational structure so that free will can
be embedded within it (the microcosmic level). Or Conway has to explain why
specifically, free will is a unique microcosmic outlier which is exempt from
analogous foundational structures for free will required at the macrocosmic level.

From the grander view, the universe scientifically started without life,
without organic consciousness. Supposedly it had no free will. Then over
the millenniums life emerged and there is to my knowledge still no very
well-established theory for the miracle of life, or how inorganic became
organized and organic and so ultimately consciousness with the possibility
of a mind possessing free will emerges. One explanation is to assume that
the universe instead started with a primordial pervasive consciousness
(panpsychism), which is not a well-received theory. Both ideas hit a dead
end: we cannot know if the universe was created from/as a deterministic event
or from/as an uncaused first cause. Appropriately, my final indictment about
the lack of critical thinking shown in Conway's paper is the logical fallacy
of false cause; correlation does not imply causation and Conway does not
demonstrate that the microcosmic is the true cause of free will. Free will
or its absence can be correlated at both the macrocosmic and microcosmic
levels and both have a deeper underlying cause (parent, and not necessarily
God) to the merely correlated properties which may exist at both spawned levels.

In plain language I think Conway engaged in yet another proof of whether
there is a God or whether there is not a God, when no such proof exists or
can exist. I mean "God" as an existential labeling shortcut to knowing the
Reason for Existence. How could one possibly prove that something which doesn't
actually exist, does not actually exist?! I don't mean that Conway literally said
this, but that it's consequential that his claim potentially suffers from the same
Incompleteness malady due to a chained reasoning sequence of local paradox produced
contexts of contradictory QM interpretations.
Conway's proving tool, QM, is like using a screwdriver when a wrench is required
and is inappropriate, similar to how Penrose's attack on strong AI with GIT, failed.

The statement of the (strong) Free Will theorem is:
The Free Will Theorem. The axioms SPIN, TWIN and MIN imply that the
response of a spin 1 particle to a triple experiment is free—that is to
say, is not a function of properties of that part of the universe that
is earlier than this response with respect to any given inertial frame.

"Conway and Kochen prove this theorem by contradiction, that is they assume
the theorem is not true and show that leads to a problem, in this case the
the *contradiction comes in the form of the Kochen-Specker paradox*."

Title: Quantum Scholasticism: On Quantum Contexts, Counterfactuals,
and the Absurdities of Quantum Omniscience
Authors: Karl Svozil
What happens if one insists on the use of two–valued states outside of a single
context by considering quantum propositional structures still allowing "a
few" two–valued states? In this case, the invocation of counterfactuals and
the "scarcity" of two–valued states accounts for some consequences which,
depending on the disposition of the recipient, appear "mindboggling" to absurd.
By bundling together propositional structures giving rise to such "mindboggling"
properties, one arrives at the KS conclusion. For such finite compositions of
observables, the mere assumption of a globally defined truth table results in
a complete contradiction. Alas, by contemplating the situation not bottom–up as
usual, but top–down; i.e., from the point of view of KS, it is not too difficult
to derive "mindboggling" statements from absurdities. Indeed, the principle of
explosion (stating that ex falso quodlibet, or contradictione sequitur quodlibet)
which, due to the pasting construction of Hilbert lattices, holds also in quantum
logic, implies that *"anything follows from a contradiction."*

motl said [re Conway's]: The free will theorem is a very cute sharpened reformulation
of the hidden variables no-go theorems that can be phrased in the following way:
'If experimenters have free will, then so do elementary particles.'

SH: I think to be significant then the converse needs to be true that
'If elementary particles have free will, then so do experimenters.'?

I told both Conway and Kochen, the AMS and various other experts that I
think Conway and Kochen made a very poor choice of phrase with "free will"
because their concept of "free will" is not related to the initial
conception of free will in either philosophy or religion which both assert
that the primary purpose of free will is some kind of capacity for choosing
between the "good" and the "bad" (whatever that means).

I prefer to call their concept "physical indeterminism".

I sent additional mathematical-physical arguments both for and against
Conway and Kochen's new theorem to them, the AMS and a few other experts,
but these particular arguments are highly advanced, esoteric and not
currently understandable in a deep way.

This is because, over 100 years ago, Einstein said that "No one really
understands the photon", and then years later, Feynman said that "No one
really understands quantum mechanics" and then Feynman said that
wave/particle duality is likely the underlying essence of QM.

I can actually prove to any expert in about 2 minutes or less that what
Einstein and Feynman said is still true. For example, I happen to believe
that John Baez is some kind of genius for two related reasons, but I have
read John's paper "Quantum Quandaries" and I don't believe that this paper
really helps with foundational issues of QM.

If you don't think I am correct about this belief of mine then here are two
homework exercises to try:

1) Correctly explain the origin of wave/particle duality for fermions.
(Way back in 1997, I tried to do this via string theory physics, but I
failed in this attempt and so has anyone else who thought about doing
this).

2) Correctly explain why the wavefunction in QM (which is intimately
related to wave/particle duality) is fundamentally non-sequential rather
than sequential. This non-sequential character of the wavefunction has
already been confirmed experimentally via an IFM (interaction free
measurement) experiment.

SH: I think he chose the phrase "free will" deliberately because a more accurate description wouldn't provide him with invitation to give lectures in Japan, New Zealand, Los Angeles etc.

Professor John McCarthy, the inventor of Lisp, once stated that a thermostat is conscious because it feels cold or hot and responds. Later he said he realized the statement would be "controversial". He said the thermostat feels: it's too cold in here, it's too hot in here and it's just right in here.
I think that both McCarthy and Conway chose a provocative term to increase funding, so that there choice of words accurately reflected their intentions. Conway attracted a theologian to his audience. McCarthy was defended by somebody who said that he was just trying to establish that consciousness was a continuum. Is free will a continuum? How many tickets would they sell by advertising "Come hear a new and improved 'no hidden variable' theorem." I too have what I consider to be a self-referential quote that Conway used in one of his own papers,
Richard Feynman once said that "If someone tells you they understand quantum mechanics, then all you’ve learned is that you’ve met a liar."

motl said: The free will theorem is a very cute sharpened reformulation of the hidden variables no-go theorems that can be phrased in the following way: 'If experimenters have free will, then so do elementary particles.'

Since elementary particles existed billions of years before life humans memory, intelligence and volition evolved, it is not the case that humans transmogrified the universe retroactively with free will. So if elementary particles first had free will then the universe is in a favorable position to support the evolution of intelligent life with free will. Is this converse of what motl stated true? It seems more important than the degraded and trivial Conway usage of free will which attempts to make yet another K-S theorem grandiosely meaningful.

It isn't the mathematics that I dispute. It's the blatant misrepresentation of his result as a result that merits a title such as "The Strong Free Will Theorem" that leads people to believe that Conway's notions are somehow meaningful to people's lives. The paper doesn't prove if the universe is (in)deterministic or not, which may actually impact a mature concept of free will. It is mere hoopla that they use to peddle at medicine shows (except to quantum theorists).

There must be some reason why the crazy and insane scientists of the world came up with things that we cannot live without. Such as electricity, flight, the automobile, and so much more. One such scientist of his day was Alfred Wegener, who hypothesized on the theory of techtonics.
