At this point I'm not even talking about Science but logic and a distaste

I believe that human intelligence is a product of Darwinian evolution

about this, but I can't think of any further way to make my point.
We'll have to disagree to disagree.



You shouldn't, perhaps.
May be it would be enough to just ask John Clark to push his logic a bit
further.

I agree that human intelligence is a product of Darwinian evolution, but
this assumes some mechanism, and thus Mechanism.

Then the discovery of the universal machine shows that machine intelligence
is a (logical) product of the elementary operations in arithmetic.

Then machine can see their own limit, and are statistically forced to guess in something which can't be a machine, as arithmetical truth, for example.

We don't need to know what consciousness is.

If we can agree that consciousness is
1) undoubtable
2) incommunicable
3) invariant for digital substitution at some level.

I believe in 3) but not with 100% certainty.

You don't need to " believe" anything, just to agree 'for the sake of the argument.
And there is no certainties.





Isn't it possible that,
in fact, I was created just a couple of hours ago by adding the
molecules of the food I had for lunch to my body, and that before I
was someone else and we just happen to share the same (now fake)
memories. I don't think this is the case, but can I be sure?

Yes that's an arithmetical computational history. It exists, and so you have to take it into account in all experience/experiment of physics you can do. But if the normal measure behaves a bit, you might need to take into account that and similar "rare" history only to get the 10^1000 billionth correct decimal.

In arithmetic you have all computational histories, and by the FPI you are distributed in all of them. Physics get statistical at the start.

Memories are not really fake of not fake. They are appropriate, or not, relatively to probable histories.




Then we can understand that the mind body problem becomes a body
statistical-appearance problem in the whole of arithmetic (not just the computable sigma_1, but the non computable pi_1, sigma_2, pi_2, ..... up to
arithmetical truth).

This generalizes both Darwin and Everett on arithmetic.
It shows a non negligible part of what the physical reality is the border
of.

Machines cannot not be religious.

It is unavoidable, unless you deliberately program them to not look deep
enough,  ... of course.

I like your ideas, but I still lack the technical knowledge in some of
the steps to feel confortable using them.


I appreciate you tell me. Normally UDA is understandable with only a passive knowledge of what a computer is, but AUDA, where the "religion" aspect is clearer, needs a good familiarity with the gaps between computability, provability and truth, coming from the incompleteness phenomenon in arithmetical logics and above.




And, btw, you are right with the 'artificial nets'. We will not make
intelligent machines, we will fish in the arithmetical ocean and sometimes we get the chance to meet some-one, in some recognizable ways. We might
learn deep lessons in the exploration, though.

Nice.

Well, we can hope the best, but we can fear the worst. Even the bitcoin has made a little crack due to exaggerate speculation. Universal Machines, like brain, computers and cells, are really doors to the Unknown. It may be that lies plays some part in the exploration, like with the mimicking ants jumping spider which make the birds believing that they are non edible ants, when actually they are edible spider. Even Peano Arithmetic get some more provability power when the false axiom "PA is inconsistent" is added. Lies can run deep.
