I don't mean the white rabbits from the Turing machine, I mean the ones
outside it. If we accept that an abstract machine can just exist, without
benefit of a separate physical reality, why not also accept that
non-computational talking white rabbits can also just exist? That is, why
should computations have a privileged ontological status in the everything?
