Well, Bolotin's reasoning seems fascinating at first sight, but it's worth recalling that there is a VERY strong realist assumption hidden there, namely, that the universe constantly "solves" Schrödinger's equation in order to work. Now that's two subtly (but crucially) different things to say that that: (1) certain properties of our world are well *described* by Schr's Eqn., and that: (2) certain features of the world *depend* on computational properties of Schr's Eqn. What one can say for sure is that Schr's Eqn. is our representation. To say anything stronger than this would require an independent defense of scientific realism (certainly not a trivial task).
