I agree that there maybe something we can't simulate. This has nothing to do wtih the paper. The paper makes no contribution to this discussion besides stating the obvious, with no definitions, no non-trivial insights. Moreover, it outright misleads the reader by claiming to "prove" something.

I can write a useless and poorly-argued paper about P != NP (or P = MP), and it would be twaddle regardless of whether or not I guessed the equality / inequality correctly by pure chance.
