Jonathan Halliwell explains how quantum decoherence is key to understanding how we transition from a world with a wave-like nature of matter and energy to the classical macroscopic world that we’re used to.

We do see relativistic and quantum effects at macro scales. Not necessarily day to day, but many experiments have shown it’s quite a blurry line between quantum states and ‘normal’ states.
From things like Bose-Einstein condensates having quantum properties across the entire mass, and experiments showing that electrons and even things as big as protons still can exhibit wave-like properties, amongst many other phenomenon, it’s blatantly obvious there is no hard line.
I think there was some publication showing wave-like interference by performing the double-slit experiments with fullerenes, so molecules of about 60 carbon atoms.
