Even after reading all the comments in the thread, I will restate what I said: one must define what they mean by consciousness before discussing it. Even in the example here, you are quoting people talking about consciousness without defining what they mean by it.
It seems that you accept that most things that people would ascribe to consciousness, eg, the ability to perceive their environment, store and retrieve relevant information, to synthesize theories and plans, to incorporate those meta thoughts into higher order thoughts (ie, self-referential knowledge), etc, can be explained by materialistic considerations. But you have another thing that you also call consciousness that is definitionally mystical, something physical explanations can make zero inroads to explaining. Please give some concrete examples of what cannot ever be explained.
