I agree that one or both could be wrong. But why insinuate that they are BSing? Also, sometimes, two different theories assert the same thing, but in different ways, and that can include the “assumed basic ontology”. Mechanism illustrates this completely, as you can take any terms of any Turing-complete, without induction, without changing any conclusion about the “same” reality. It is more the relations between the “objects” that counts. In fact, eventually it is the relations between the relations which counts, which imply the necessity for the mind to invoke the infinite, even if we do not “reify” it into the ontology (like with the class of all sets is not a set, or that Plotinus Number of the Numbers is not a number, etc.). Reality is independent of the theories. Different theories can handle well different aspect of Reality. Sometimes they can handle well the same aspect of Reality, yet in a completely different way, and this usually announce fertile marriage between the theories. (Examples in mathematics exist between braids and spin statistics, or group and particles theory, of topology and algebra, etc). > > The luxury (or fun) of math and even applied math is it doesn't matter if > whether you think of the entities of a theory being fictional or not.

For someone open to the idea that Reality might be Mathematical, if not Arithmetical, if not sigma_1 arithmetical only, the distinction between applied and pure mathematics makes no more much sense fundamentally. It becomes a bit like the difference between artificial and natural, once you embed the researcher in the Reality that it researches. So that difference is also natural, and indeed almost unavoidable when the universal machine develops a big ego, and feel different. Monism favours that embedding of the “subject” into the “object”. QM without collapse is essentially QM + the axiom asserting that the physicists obeys to the physical laws. Similarly, with Digital Mechanism, Gödel’s work is an embedding of the mathematician in the mathematical reality.
