Interesting but I struggle to see how this hypothesis could ever be proven or disproven. If it can’t actually be tested then I don’t see how it presents more scientific value any other religious or superstitious belief.
Here's another way of framing it: qualia, by definition, is not measurable by any instrument, but qualia must exist in some capacity in order for us to experience it. So, me must assume that either we cannot experience qualia, or that qualia exists in a way we do not fully understand yet. Since the former is generally rejected, the latter must be true.
You may argue that neurochemical signals are the physical manefestation of qualia, but making that assumption throws us into a trap. If qualia is neurochemical signals, which signals are they? By what definition can we precisely determine what is qualia and what is not? Are unconscious senses qualia? If we stimulated a random part of the brain, unrelated to the sensory cortex, would that create qualia? If the distribution of neurochemicals can be predicted, and the activations of neurons was deterministic as well, would calculating every stimulation in the brain be the same as consciousness?
In both arguments, consciousness is no clearer or blurrier, so which one is correct?
So our subjective experience must “exist” because we experience it? This seems rather circular. My personal take, consciousness is an artifact of how our brains work. It’s not a thing that exists in any physical sense, it is simply part of the model our brain structures the stimulation it receives throughout the course of our lives.
All of science is based on the assumption that what is observed and experienced exists. You cannot gather data without at some point experiencing some representation of that data. In this sense, qualia is the most real thing possible, because experience is the essence of evidence.
So how do you measure qualia? What is it made of? How is it actually defined? How do you detect if qualia is present in something other than your own head?
I stand by my statement that qualia is simply an artifact of our cognitive architecture. You are welcome to disagree but the arguments you are presenting fail to convince me in the slightest.
