This is highly misleading. The arrow of time is not thermodynamic, it's quantum. It's defined by increased entanglement, not increased entropy. That's not at all what I remember from physics class when I was at university, and would seem to imply (incorrectly) that non-QM models can't produce an arrow of time.
