Is it really surprising that we have a first person subjective experience? We know that we are incredibly complex things, constantly integrating and acting on very complicated external stimuli. Such a system should have references to its own body and its own neural states, its train of reasoning should frequently include itself, its focus will drift forward and backwards in time... this is just how a system like this would work. If the system communicates about its state then its language should have referents to these internal states, referents like "experience", and "feels like", and "I understand". Is that surprising? Wouldn't it be surprising if it wasn't like that? I don't think you need to invoke an essentially mysterious "conscious" property of the mind to explain that.
