But the argument shows it's absurd to think the room is conscious. What if the person in the room takes a coffee break or goes on vacation? What connects the next computational step they do to the previous one and the next... which then somehow gives rise to a fragment of qualia. That seems like an impossibly complex and unlikely scientific theory.

Regular meat-and-bone people lose consciousness all the time, and regain it later. No big deal.

Whatever index card system or similar the operating procedure in the room prescribes for keeping track of state?

We don't have any 'scientific theory' of qualia. We don't even know if they exist, or how they would manifest in the physical world.

Since we don't know much of anything, I don't know whether a fragment of a figment would be more or less weird than the figment itself. Or whether we would even have fragments.

It's probably too early to try to have a theory of qualia that would apply here?

You're missing the point. A bit is just some electrons. It could be a scribble in a notebook. But consciousness integrates several pieces of information into a coherent experience. The bits in an index card system could as well be some scratchings of graphite in a notebook. How would consciousness arise from graphite in a notebook?

> We don't have any 'scientific theory' of qualia. We don't even know if they exist,

I differ on this. The only thing I know for certain the universe contains is qualia. You, the idea there is a "me", atoms, bits, axons and electric potentials are merely ideas, which "I" apprehend as qualia.

> or how they would manifest in the physical world.

Correct, that is the question. But the Chinese room thought experiment shows it's not merely by information processing. I mean, atoms in a room are processing information - they are computing the next state of all of the atoms in the room. Are they conscious? How about a subset of those atoms? Are those conscious in a different way?

The point is that the consciousness-is-computation idea is just too weak to even be a physical theory.

So what? There are lots of REAL physical processes that are disrupted in a human being when they lose consciousness.

The point of the Chinese Room is to show that information processing alone is insufficient for consciousness. For example is information processing happening when the person pauses for a minute - or not? For a second, for a millisecond? What about when the pen comes off the paper? What about when he's sharpening his pencil? How exactly does the consciousness=information processing idea work for these situations? It's a nonsense idea that doesn't hold up to careful inspection.

And it's exactly akin to saying we get nuclear power by simulating a nuclear power plant in a computer.

On the other hand, if we believe that consciousness is like an ordinary physical property of the universe, either emergent or fundamental, then it should be related to other physical properties, just as electromagnetism is to mass and energy.

The conscious system is so high above the guy shuffling rulebooks and slips of paper it has no concept of him. A billion years might pass for the Room to experience a second. Just as we have basically no concept of the baroque quantum-molecular-cellular machinery of our brains. There are very roughly 10^15~18 light-sensitive molecules in your eye so you can see. With our best computers it's very hard to precisely simulate a single one of them. Just ponder the insane scale.

It's just usual neurodegenerative disease. Happens all the time.
