I agree that conciousness of people is not "special", but why the need to add in an extra meta physical quantity of "conciousness". I agree it is probably a spectrum, but I think it is more just an emergent quantity.

People are just relatively high up on the scale so its different to imagine what other types of conciousness would be. Yes it is difficult to say what exactly is going on in a human brain, but I believe when you think it is entirely just a physical process, some very complicated electro-chemical interactions.
