An interesting assertion. I don't think it's valid to object that this is just about hard-to-solve equations. As I understand the article, this is the argument:

1) It's not possible to directly observe a macroscopic quantum object. This is because the act of observation collapses the wave function.

2) It's possible in theory to describe macroscopic quantum objects in the solutions to Schrodinger's equation

3) That solution for macroscopic systems is NP-hard

4) A physical theory that can neither be observed nor modeled is "nothing more than [a] nontestable empty [abstraction]"
