        If you say so. We can still listen to the machine, and compare with 
nature.
        When we compare with nature we find that some things exist and some 
don't.


    Like other worlds don't exist, or atoms don't exist ... the question about 
what
    exists hasn't been answered yet. Or indeed the question about what it means 
for
    something to exist.
    So is it your view that no matter what comp predicts it's not falsified 
because it
    may be true somewhere else?


I find it hard to read that into what I wrote. (Unless "no matter what comp predicts" is a slightly awkward, but potentially rather funny, pun?)

But anyway, no that isn't my view. Either comp is true or it isn't, which is to say, either consciousness is Turing emulable at some level, or it isn't. And if it is, either there is some flaw in what Bruno derives from that assumption, or there isn't.

But the question is about how to test comp. Bruno has offered that we should compare its predictions to observed physics. My view is that this requires predictions about what happens here and now, where some things happen and some don't. "Predictions" that something happens somewhere in the multiverse don't satisfy my idea of testable.
