This is an astute comment. The MGA (and Maudlin's argument) supposedly
works by producing a physical philosophical zombie under computationalism.

Isn't this at the crux of the scientific study of the mind?  There

seems as good a working hypothesis as "Yes, doctor".  And in fact it's

I make no assumptions on this.  Watching life on any random planet

is one of these activities takes billions of years to do.


But watching one randomized evolution will mostly produce lifeless 
planets.  So one would want to do Monte Carlo simulations to get a 
statistically significant range of interesting planets.  Thus increasing 
the size of the problem by a factor of M^N where M is the size of the 
statistical sample you want and N is the number of variables to define a 
"world".






Further, there are no limits to what it could explore. It could,
for example, explore possible planets in universes with different
laws of physics. There is no physical way for the intelligence to
ever visit these places, but they are not out of sight from an
intelligence so vast. And if mathematical realism is true, these
discovered places represent genuine discoveries, rather than
imaginings. There are unlimited riches available in the universe
of possibilities of mathematics. An ultraintelligence could no
doubt spend many eons searching through this space, finding new
connections between things, in its effort to learn everything.


But why is it motivated to learn anything at all?  Are we
supposing that humans programmed this in and the Supeintelligence
can't change it?


Whatever its goals may be, they are not harmed and likely helped by 
increased knowledge, creativity, intelligence, efficiency and 
computational power.


A super intelligence that doesn't have the goal of maximizing it 
knowledge is likely be displaced by the superintelligences which do.


How so?  According to your theory they are just interested in 
mathematical knowledge.  Are you supposing they would compete for 
energy/entropy?  and hence enter into warfare?

 What did you find so convincing? My scepticism is immediately aroused
 by humanoid ETIs. There's no good reason why intelligent animals
 should be humanoid. Plus there was that photo of ET that was recently
 discovered to be of a mummified child.

 The point Fermi makes is that any technological civilisation capable

 into artifical structures, such as dyson spheres. This makes me
 sceptical about ET conspiracy theories. If ET exists, they should be

I would second this. Fermi's argument would suggest that if
ETs were abundant in the universe and if they persisted they
would be very apparent. The lack of such clear evidence
suggests that ETs are not widely abundant in the universe,
they may not last very long (we may be headed down that path)
and if they do exist they are separated by distances far too
large for travel and maybe too distant for even radio
communication.

they soon become a small fraction of what will occupies that mind. 
Most of what will fill such a mind will be information extracted from 
mathematics, which is equally accessible and common to all such minds 
regardless of the universe they start in.


What kinds of things might preoccupy a mind the size of a star? There 
are certainly many things it could do, but what might it choose to do? 
Obviously to get to its point it had to do much learning, discovery 
and exploration, the continuation of such is one possibility. Bordom 
is another great concern for an entity that can think so fast and

To a Jupiter brain, our most complex physical theories would be as trivial
as Tic-Tac-Toe. It stands to reason then, that whatever the particularities
of the starting conditions for the ultraintelligence, they soon become a
small fraction of what will occupies that mind. Most of what will fill such
a mind will be information extracted from mathematics, which is equally
accessible and common to all such minds regardless of the universe they
start in.

What kinds of things might preoccupy a mind the size of a star? There are
certainly many things it could do, but what might it choose to do?
Obviously to get to its point it had to do much learning, discovery and
exploration, the continuation of such is one possibility. Bordom is another
great concern for an entity that can think so fast and exist for so long.
Entertainment is a second possibility activity for such ultraintelligences.
A third possibility is doing good for other beings.

Humans are far behind the hypothetical intelligence of a planet-sized
brain, and yet we have largely figured out the laws of physics in our own
universe. Physics, and chemistry, as a source of new discovery and insight
might soon dry up under the anylsis of an ultraintelligence. Biology too,
once the ultraintelligence scanned and analyzed the DNA of every speices on
Earth and reverse engineered the course of evolution and adapdation going
back billions of years. Observation of far away planets may be possible
through the engineering of truly colossal telescopes, but it would likely
prove frustrating.

An optical telescope with an apeture equal to the diameter of the moon
could only resolve objects larger than a mile at the distance of one light
year. To keep the same resolution while looking at something 1,000 light
years away and the diameter of the telescope's aperture has to increase
another thousand times. At this point, the telescope would be over 2
million miles in diameter. Using such a telescope to view an Earth-sized
planet 1,000 light years away would yield an imagine a few thousand pixels
by a few thousand pixels. It would be enough to tell whether or not there
was life on the planet, and perhaps pick out the existence of cities, but
all told it is still a small amount of information returned for such a
massive investment of material and energy.

This is a problem for ultraintelligences. Even with massive investment in
instruments to collect information from the physical realm, such
information comes in only as a slow drip compared to the
ultraintelligence's capacity to process that information. Fortunately,
there exist alternatives for such a mind to meet its thirst for knowledge.
By using just a fraction of its available computing power, it could
simulate the entire history of life on an Earth-like planet and in the
process learn everything there is to know about it.

All movement and associated computation that occurs on our planet is driven
by energy. Nearly all (99.97%) of the available energy on earth comes from
the sun, with the rest coming from radioactivity and tidal energy. This
amount of energy is almost inconceivable. When quantified, it

This is in part why biological systems are massively redundant. 

Large megastructures have other problems. Remember Gauss' law that if you 
integrate over a gravitating mass you get that mass or 4πGM. As a result 
integrating a Gaussian surface inside a shell of matter returns zero and 
the net force on any mass inside is zero. Hence the gravitational potential 
of a Dyson sphere interior is constant, which means it is not bound to the 
star. This means the two will drift apart. The same holds for a ring world; 
it can drift relative to the star within the plane of the ring.

We see no evidence of large complex structures, Tabby's star aside I 
suppose. Though that is likely due to something natural and not a Dyson 
sphere. It also is the case these things would be enormously complex.

I would second this. Fermi's argument would suggest that if ETs were
abundant in the universe and if they persisted they would be very
apparent. The lack of such clear evidence suggests that ETs are not
widely abundant in the universe, they may not last very long (we may
be headed down that path) and if they do exist they are separated by
distances far too large for travel and maybe too distant for even
radio communication.

I think Brent has a point. It is similar to saying that we humans are
more likely to colonize Mars before we colonize any extra-solar system
of planets. I think the idea of transcension projects this issue into
far more extreme territory. So I tend to think if alien spacecraft
really did appear here that it would be in some ways fairly ordinary.
Highly extraordinary accounts are less probable.

Wormholing to other cosmologies or trying to use rotating black holes
to pass into another cosmology or region is fraught with troubles.
Violation of chronology protection and censorship by horizons is
equivalent to violating theorem results in quantum mechanics. These
things may not be physically possible.

There can also be problems with building structures that can repair 
themselves and grow faster than the rate at which they degrade. Biology 
shows that it is possible for such structures to exist, but it's not so 
easy to get to such structures.


The more critical parts a system has that all must be copied perfectly 
for the copy to function, the smaller the error rate per part can be. On 
average, you need to have more than one working system per doubling for 
there to be exponential growth. This means that the required fidelity 
for copying critical parts should be better than 1/N where N is the 
number of critical parts.

than philosopher of mind that physics is confronted to conceptual  
difficulties, Mathematicalism explains also directly Wigner’s remark

in violation of very elementary logic!





This then leads directly to the zombie problem. In fact it leads  
even beyond this, because as you go on to say vis-a-vis 'number  
reductionism', strictly speaking there would be no independent  
justification for the zombie as an 'emergent' causal entity, since  
ex hypothesi all 'causality' has already been accounted for at the  
level of elementary particles, fields, strings are what you will.


Or number, yes. If the number theorist extracts the physical laws from  
numbers, that might continue for one of two millennia, but not much  
more, I think. The key advantage of computationalism is that we get  
the modal nuances, and indeed physics is one of those nuances.






Of course, a mechanist knows that at its substitution level, he has  
the same causal power than its components when betting on some  
reality, but we can never know what are those components in a  
rational way, and our causal power (free will, or will) is a higher

I do understand that it is counter-intuitive. Doubly so in our  
"aristotelian era".


Mechanism is no threat on the physical science. Mechanism is only a  
threat to the metaphysics forbidding the physical laws to be  
reducible to something non physical.


More than that, I think your theory makes physics necessary.


Yes, indeed.



But it's not clear what physics it requires and whether it is  
necessary only to avoid solipism.  It seems your theory would  
naturally lead to solipism.


It is necessary to stay rational *and* keep computationalism.  
Mechanism cannot be solipsist, because it justifies infinitely many  
different universal machines, with different computations/indexical- 
histories. Now, a form of solipsism could still logically exist, but  
comp predicts that it go away if the number cohere enough to get a  
first plural notion, as defined in the UDA (that we get the "split" on  
collections of machines). This is the quantum solution of avoiding  
solipsism. Up to now we do get QM, so no need to think that mechanism  
has not the intersubjective agreement.











What happen is that with the computationalist theory of mind, it is  
easier to explain the illusion of matter to a relative number:state  
in arithmetic, than consciousness to a piece of primary matter (not  
yet seen by anybody).


A real lover of primary matter should love the theories S4Grz1, Z1*  
and X1*, because they are pointing on experiment capable of  
detecting it.


I only love knowledge.  It is a mistake to fall in love with theories.


We have only experiences, theories, and personal interpretations.

You are bit easy here. I said that the lover of knowledge should be  
very happy with S4Grz1 & Co, because it makes possible to test  
Aristotle primary matter idea, and so, like with all scientific  
theories, helps in the search of truth and knowledge, of course.








Until today, it did not. But tomorrow? Nobody knows.

Bell (and CHSH, and Aspect, ...) illustrated that EPR was not just  
"philosophy/opinion". Similarly,  the mathematical theories S4Grz1,  
Z1* and X1* illustrate that the mind-body problem is not just  
"philosophy/opinion" either.


Bell is (rightly) famous for suggesting an definitive  
experiment...not just an illustration.


Here too. In particular the violation of Bell's inequality itself can  
be tested in the machine's physics. That is detailed in my long thesis  
version.
It leads to complex math, but that is hardly an argument of falsity.  
If the results were not ignored, (for pseudo-philosophical reason  
intolerable in science), we would have already refuted  
computationalism (or that classical indexical weak formulation of it),  
or improved it, notably by noting which of S4Grz1, Z1* and X1* are  
closer to the physicists' quantum logic. Note that if physics is  
entirely explained in S4Grz1, that would be a case for some sort of  
solipsism, but not ecaxtly the common one, and also, there are few  
chance that can happen (because quantum logic obeys the excluded

The time traveler interpretation is extremely implausible. Time travel 
would force us to revise much of our foundational understanding of physics. 
Again I can't prove this, though I will say I think quantum gravitation 
will remove solutions to the Einstein field equation that involve closed 
timelike curves. Such solutions that permit time travel and travel faster 
than light violate the Hawking-Penrose energy conditions that the stress 
energy tensor obeys T^{00} ≥ 0.How this happens is similar to Dirac's 
relativistic QM solution that filled the negative energy momentum like cone 
with vacuum states. These as occupied states were not directly accessible 
as real particle states. Of course we can't completely rule out some deeper 
foundation of physics that circumvents this. However, if so any applied 
physics or technology that employs this would be enormously more advanced 
than anything we can remotely even imagine. I would argue that makes this 
far more unlikely.

Carl Jung wrote a book on the issue of UFOs. He cited this as an instance 
of how our symbolic representations are shifting. We have symbols that are 
more based on science, and correspondingly this he argues is working it way 
into our mythic narratives. We seem to be seeing something of this sort 
with quasi-religious ideas of ancient alien astronauts, UFO cults and even 
the huge interest in superheros. Superheros are serving a rule similar to 
the pantheon in polytheistic religions of the past. This has a lot to do 
with what is occurring in the inner space of human consciousness far more 
than anything with outerspace.

In 13 October 1917, in Fatima, Portugal, 3 to 4 people claim

apparition of Virgin Mary to three children.
The probability of all these people lying is astronomically low. Does
that lead you to conclude that the sun danced in the sky on that day?
