Specifically, consciousness is self-referential information processing. As I said in... Okay, looks like I didn't say that in this thread. Oops.Okay, so your position: Consciousness is a class of information processing
Makes your entire post moot, but that's not your fault. I've gone over this in considerable detail in past threads, but I'm happy to cover it again.
Look at it this way. A thinking entity needs the following:
Input - sensory data of some sort
Memory - the ability to memorise past input and output, and hence to learn
Logic - the ability to make decisions based on a mixture of input and memory
Output - some way of interacting with the world
I call this simple creature (which can be simulated with about 50 transistors) aware, but not self-aware. Dennett describes a thermostat as conscious, but I describ it as merely aware.
To be conscious, one must also be aware of oneself. That is, you need feedback from the logic circuits to themselves. Now we're looking at maybe 100 transistors.
This creature (or circuit) can think and feel and act and learn, and it can reflect on the process by which it does this. Not very much, mind you; it only has about 8 bits of memory, total. But it can do it.
We have a whole bunch more RAM and logic circuits, but self-reference is what makes us different from, say, a clock.
Edit: I did mention feedback loops, but the reference isn't very clear unless you've read Godel, Escher, Bach. If you have read Godel, Escher, Bach, then you missed the point and need to read it again.
