I want to make sure I understand what you are saying here. Is it just
that our machine will always get bound up in the infinite tape problem.
We would interpret this to mean that it is NOT a truly universal
simulator or model maker? So whether our machine is using analog or
digital, sequential or parallels processing makes no difference. It may
be a spectacular super computer, but it can never duplicate a thing like
life.
I've found that a good way to think about this fallacy is in terms of
Frank Tipler's immortality machine. Recall he predicts that we will all
live again and be immortal in some future all powerful super computer.
See THE PHYSICS OF IMMORTALITY.
In contrast, what we're saying here is that this is NOT realizable in a
machine no matter how powerful it is. So we ought not to expect that at
some point in the future we will all become immortal as Tipler predicts
and live our lives forever in a machine. This is just another way of
saying that a machine can't ever come close to mapping qualities that
emerge from the modeling relation.
