I think *you* believe in magic. You believe that
if you write down hypothetical truths about what
an immaterial machine would believe, you can conclude
that everything has been conjured up by an immaterial machine.

It's like saying you can go from making a theoretical study of the
aerodynamics of Pegasus to taking a ride on Pegasus's back.

You're still not getting it. PM isn't a non-computable number.
It isn't mathematical at all. You really do think in a box..

!!!!

In arithemetic. people write down problems on blackboards and solve
them.

There is no immaterial existence at all, and my agreeign to have
my brain physcially replicated doesn't prove there is.

No. I don't have to deny their truth. I just have to deny that
mathematical
existence is ontological existence. As I have been

Since it does not exist, it does not contain anything.

Same mistake
All you can prove is that *if* the UD existed *then* it would
contain such-and-such. But it doesn't actually exist.

That is never going to get you further than mathematical existence.
You still need the futher step of showing mathematical existence is
ontological RITISAR existence.

So? If you develop a correct argument that you are running on a
computer
when actually you are a BIV, then the BIV you will come up with that
argument too. Any argument whatsoever can be undermined by a sceptical
hypothesis, and there are many.

The way to prevent it is the same way that all sceptical hypotheses
are prevented. You just note that there is not a scrap of evidence
for them. The only upshot of scepticism is that there is no
certainty, and we have to argue for the position of the greatest
plausibility.

I can't be "in" something that has merely mathematical existence, any
more than I can be "in" Nanrnia

False. You are treating all reasoning as being assumptionless and
apriori. Both me's could have arguments of equal validity, but one of
the argumetns could have true assumptions and the other false
assumptionsm
because the truth of the assumptions (and hence the soundness of the
argument)
depends on external factors which vary.

I don't need to strenuously argue against that there is something
special about me that makes me un-emulable , or un-BIV-able.
I just have to note that there is no evidence for either hypothesis.
The burden is on the sceptic.
