programs that make non-naturalistic predictions specifically about what AIXI(tl) will experience after smashing itself have to treat the chunk of the Universe carrying out the computation as special,

Well, any program AIXI gives weight must regard that chunk of the universe as special. After all, it is that chunk that correlates with AIXI's inputs and actions, and indeed the only reason this universe is considered as a hypothesis is so that that chunk would have those correlations.

The kind of "special" you're talking about is learnable (and in accord with naturalistic predictions); the kind of "special" I'm talking about is false.
