I found the article rather confusing: it starts out by saying look, the laws of physics make sense forwards or backwards. But we only see one kind (entropy increasing) of process. Why is that? Entanglement.
Is there something about entanglement that is irreversible? As the article says "it is the loss of information through quantum entanglement, rather than a subjective lack of human knowledge, that drives a cup of coffee into equilibrium with the surrounding room." Okay, but then why don't we ever see the reverse making coffee depart from equilibrium? Something like the acquisition of information through breaking entanglement drives a cup of coffee away from equilibrium.
