Somebody has described how you get qualia?
Well, perhaps not thoroughly enough to form instructions to build a ghost in the machine, but I thought Hofstadter gave it a red-hot go in Gödel, Escher, Bach back in the day. As he has it, in a nutshell, awareness is an emergent property of a sufficiently complex system of nested feedback loops. This notion is kind of reinforced by the fact that your thinking becomes more intelligent as you get more self-referential and meta about it; thinking about thinking leads to better thinking.
A heater with a thermostat can be said to have an extremely crude awareness; keep adding layers of feedback enough times and you get a person.
"complexity theory which describes how you can get emergent phenomena in complex systems when you have the right blend of chaos and order, for instance qualia in your brain."
