Earlier quoted context omitted.
Do you consider an infant to be conscious? Or electrons?
i think it's still an open question how "conscious" that infants and newborns are. It really depends on how you define it and it is probably a continuum of some kind.
I think the jist of the article is that we will use whatever definition of consciousness is useful to us, for any given use case
Much the same way treat pigs vs dogs, based on how hungry or cute we feel.
