Why some kinds of information processing and not others?
As I wrote elsethread: why are some types of information processing "privileged" to create phenomenal experiences, while others run "in the dark"?

I have no idea. If that's what the hard problem of consciousness boils down to - we don't know why some complex math produces consciousness and other complex math doesn't - then it boils down to "we haven't found the means to sufficiently analyze the math that does produce it." Which would turn it into... a math problem?
My suspicion is that it has something to do with evolutionary pressure. Consciousness is something that evolves when systems that include their own existence within their data model become much more likely to continue existing versus those that don't. Statistics does the rest.
Using Rovelli's example: why some clouds create a thunderstorm and not others? It is just a complex phenomenon that happens only under right conditions.
Let us classify the information processing along two axis: a) low-level (evolutionarily ancient), direct stimuli-response, vs high-level (involving prefrontal cortex) b) processing stimuli from the outside world (sound, light) vs internal stimuli (tactile/pain ... all the way to internal stimuli originating in brain - 'thinking about thinking')
Note that both are continuous scale, not binary.
The consciousness would then be the high-level processing of internal signals. Obviously, consciousness also results being on continuous scale.
It should be kind of obvious due to the fact that we are conscious about our human self, not neurons, not brains, not microtubules or any other random implementation detail. We have zero clue what is going on in our brains, but we do have a high level description. Just as our brain can take some random electrical impulses from our eyes and decide that that's a "cat", it can take all the other input that goes around and conclude that that's a "self". It's perception, the brain trying to figure out what parts of the world it has direct control over.
