While my post was pretty misguided (I even wrote an apology for it), your comment looks even more misguided to me. In effect, you're saying that between Lagrangian and Hamiltonian mechanics, at most one can be "true". And you're also saying that which of them is "true" depends on the programming language we use to encode them. Are you sure you want to go there?

We may even be able to observe which one. Actually, I am pretty sure that if I looked closely at QM and these two formulations, I would go with Hamiltonian mechanics.

Ah, but which Hamiltonian mechanics is the true one: the one that says real numbers are infinite binary expansions, or the one that says real numbers are Dedekind cuts? I dunno, your way of thinking makes me queasy.
