> To be fair to Bruno, he takes the idea that any computations that generate
consciousness are sufficient, so if one assumes (as per materialism) that
the mind and consciousness are, somehow, "what the brain produces", then
the question is whether the part of the universe containing the brain in
question is Turing-emulable (in principle, even if it would require
unimaginable resources in practice). So he is at least starting from a
standard materialist stance, and as it were "Godelising" it. That stance
got me as far as the MGA, which I don't really get, and I am still not au
fait with the UDA. It all sounds very interesting but I shall of course be
agnostic until - if - I manage to get my head around it.
