Ah, but macro-level systems can amplify quantum effects. For instance, the human eye -- under the right conditions -- is sensitive to individual photons.
A packet of energy absorbed and exciting a molecule in my eye, causing a cascade through a complex system still feels entirely classical. I'm not sure merely invoking "photon" is enough to imply quantum effects. It's when the behavior breaks from deterministic to probabilistic (independent of initial conditions) that we switch paradigms.
