Tim: "Solomonoff induction is simply an attempt to formalise Occam's razor around
an impractical theoretical model of serial computation."
This is distinct from a Universal Turing Machine how?
What bothers me is that from reading the Chalmers quotes, it seems like he assumes that this world is the world with the listener, the conscious people. Because 'this' world and the zombie world are physically indistinguishable from one another, then this world could be equally likely to be the zombie world and the other world is full of conscious people.
Or better yet of course, the argument is absurd and there is no external part that is what we call 'consciousness'.
