I think I have a similar view to Dagon’s, so let me pop in and hopefully help explain it.
I believe that when you refer to “consciousness” you are equating it with what philosophers would usually call the neural correlates of consciousness. Consciousness as used by (most) philosophers (or, and more importantly in my opinion, laypeople) refers specifically to the subjective experience, the “blueness of blue”, and is inherently metaphysically queer, in this respect similar to objective, human-independent morality (realism) or non-compatibilist conception of free will. And, like those, it does not exist in the real world; people are just mistaken for various reasons. Unfortunately, unlike those, it is seemingly impossible to fully deconfuse oneself from believing consciousness exists, a quirk of our hardware is that it comes with the axiom that consciousness is real, probably because of the advantages you mention: it made reasoning/communicating about one’s state easier. (Note, it’s merely the false belief that consciousness exists, which is hardcoded, not consciousness itself).
Hopefully the answers to your questions are clear under this framework (we talk about consciousness, because we believe in it, we believe in it because it was useful to believe in it even though it is a false belief, humans have no direct knowledge about consciousness as knowledge requires the belief to be true, they merely have a belief, consciousness IS magic by definition, unfortunately magic does not (probably) exist)
After reading this, you might dispute the usefulness of this definition of consciousness, and I don’t have much to offer. I simply dislike redefining things from their original meanings just so we can claim statements we are happier about (like compatibilist, meta-ethical expressivist, naturalist etc philosphers do).
I am equating consciousness with its neural correlates, but this is not a result of me being sloppy with terminology—it is a conscious choice to subscribe to identity theory and physicalism, rather than to consciousness being magic and to dualism, which runs into interactionist dilemmas.
Our traditional definitions of consciousness in philosophy indeed sound magical. But I think this reflects that our understanding of consciousness, while having improved a lot, is still crucially incomplete and lacking in clarity, and the improvements I have seen that finally make sense of this have come from a philosophically informed and interpreted empirical neuroscience and mathematical theory. And I think that once we have understood this phenomenon properly, it will still seem remarkable and amazing, but no longer mysterious, but rather, a precise and concrete thing we can identify and build.
How and why do you think a brain would obtain a false belief in the existence of consciousness, enabling us to speak about it, if consciousness has no reality and they have no direct access to it (yet also have a false belief that they have direct access?) Where do the neural signals about it come from, then? Why would a belief in consciousness be useful, if consciousness has no reality, affects nothing in reality, is hence utterly irrelevant, making it about as meaningful and useful to believe in as ghosts? I’ve seen attempts to counter self-stultification through elaborate constructs, and while such constructs can be made, none have yet convinced me as remotely plausible under Ockham’s razor, let alone plausible on a neurological level or backed by evolutionary observations. Animals have shown zero difficulties in communicating about their internal states—a desire to mate, a threat to attack—without having to invoke a magic spirit residing inside them.
I agree that consciousness is a remarkable and baffling phenomenon. Trying to parse it into my understanding of physical reality gives me genuine, literal headaches whenever I begin to feel that I am finally getting close. It feels easier for me to retreat and say “ah, it will always be mysterious, and ineffable, and beyond our understanding, and beyond our physical laws”. But this explains nothing, it won’t enable us to figure out uploading, or diagnose consciousness in animals that need protection, or figure out if an AI is sentient, or cure disruptions of consciousness and psychiatric disease at the root, all of which are things I really, really want us to do. Saying that it is mysterious magic just absolves me from trying to understand a thing that I really want to understand, and that we need to understand.
I see the fact that I currently cannot yet piece together how my subjective experience fits into physical reality as an indication of the fact that my brain evolved with goals like “trick other monkey out of two bananas”, not “understand the nature of my own cognition”. And my conclusion from that is to team up with lots of others, improve our brains, and hit us with more data and math and metaphors and images and sketches and observations and experiments until it clicks. So far, I am pleasantly surprised that clicks are happening at all, that I no longer feel the empirical research is irrelevant to the thing I am interested in, but instead see it as actually helping to make things clearer, and leaving us with concrete questions and approaches. Speaking of the blueness of blue: I find this sort of thing https://www.lesswrong.com/posts/LYgJrBf6awsqFRCt3/is-red-for-gpt-4-the-same-as-red-for-you?commentId=5Z8BEFPgzJnMF3Dgr#5Z8BEFPgzJnMF3Dgr far more helpful than endless rhapsodies on the ineffable nature of qualia, which never left me wiser than I was at the start, and also seemed only aimed at convincing me that none of us ever could be. Yet apparently, the relations to other qualia are actually beautifully clear to spell out, and pinpointing those clearly suddenly leads to a bunch of clearly defined questions that simultaneously make tangible progress in ruling out inverse qualia scenarios. I love stuff like this. I look at the specific asymmetric relations of blue with all the other colours, the way this pattern is encoded in the brain, and I increasingly think… we are narrowing down the blueness of blue. Not something that causes the blueness of blue, but the blueness of blue itself, characterised by its difference from yellow and red, its proximity to green and purple, its proximity to black, a mutually referencing network in which the individual position becomes ineffible in isolation, but clear as day as part of the whole. After a long time of feeling that all this progress in neuroscience had taught us nothing about what really mattered to me, I’m increasingly seeing things like this that allow an outline to appear in the dark, a sense that we are getting closer to something, and I want to grab it and drag it into the light.
