What makes brain computation special? Nothing. That's my whole point. Does the sewer system in NYC have consciousness? It's impossible to answer, because there's no single accepted definition of consciousness. If something isn't clearly defined, it becomes very hard to meaningfully assess whether it applies or not.

But if we built a Turing complete, sewer-like system that simulated every neuron in a human brain, it will claim that it is real and conscious for sure. There's no paradox at physical level, intuitively conceptualizing it is the "hard" part.

I think the key point in my theory is that my brain simply hasn't evolved to intuitively conceptualize it. I've asked similar questions before, including what it's like to die and be dead forever, and I can't form an intuitive understanding of it. My brain rejects the premise. But just because I can't imagine it doesn't mean it won't happen. I'm pretty sure I will still be dead for trillions of years into the future.

To your question, the answer is similar. If we remove this limitation of intuition, there doesn't seem to be a real paradox. Both you and a spreadsheet-like copy of you would each claim to be the real you, and from an outside observer's perspective, there is no contradiction.

If we accept subjective feeling as definitive proof that something exists, that opens a Pandora’s box of entities. People have deeply held subjective beliefs about things like God, afterlife experiences, out-of-body experiences, and many others. It seems unfair to me to dismiss this kind of subjective evidence in these cases, while accepting it without question for experience of consciousness.

I think this hard problem has a simple answer that people just don’t like: consciousness is a powerful (and fundamental to our "calculator brain") illusion. And yes, a spreadsheet simulating every neuron in your brain would also simulate it. The fact that it’s difficult to conceptualize doesn’t mean it’s not the answer. Similar to how we struggle to intuit general relativity, or to imagine the pre–Big Bang state of the universe (or its non-existence), or to picture what it’s like to be dead. Our intuition simply isn’t equipped for these cases, period, and it pushes back hard against them. Consciousness belongs in that same category IMO

Also, the emergence of a consciousness like illusion kinda follows from an evolutionary perspective. To survive, a "calculator" brain needs a model of the external world in order to predict how it will evolve and to act in ways that improve survival odds. Once such a model exists, it becomes almost inevitable that it also includes a model of the system itself, since the brain is also part of the world it is modeling and an agent within it. This self-referential loop is likely what we experience as "consciousness" and it becomes central to how we understand and navigate reality.

If we accept this framing, many traditional paradoxes dissolve on their own. The problem stops being "hard" in substance and becomes hard only in terms of imagination.

I don’t think consciousness exists, at least not in the way people talk about it. First, there’s no clear definition that everyone agrees on. Second, there’s no way to test whether something has it. Does a cow have it? A dog? A spider? If you can't test for it and even define it, how can you claim its real?
