This remark surprises me. Can we infer that there is a clear sense in
which a formal ZFC proof of any theorem of a paper with a Mathematics
Subject Classification number other than 03Exx (set theory) will not be
faithful to the original proof, because the latter brings in content from
branches of mathematics other than set theory?
This seems fundamentally wrong since any formalization of any theorem
surely starts with a very small set of basic concepts, but then by the
above criterion, it will be hopeless to "faithfully represent" any theorem
of algebraic topology or microlocal analysis or p-adic representation
theory since such a theorem will by its very nature contain content from
branches of mathematics that go beyond the initial set of basic concepts.
