In Daniel Dennett's Consciousness Explained, he described and explained how subjective experience or qualia or consciousness in general is just a result of biology and nothing more. The word "Consciousness" is very broad and can become vague so let's just focus on qualia or internal subjective experience. Could it really just be a result of pure brain biology? Is there any latest research how neural algorithm or network property can give rise to it? Someday. Can we create pure mechanical sentient being with internal subjective experience? This would be the definite proof that consciousness and qualia is just a special properties of certain network algorithm or processes. Is this possible? I'm quite undecided about this... one day believing our qualia is due to something extra.. other day believing it is just a result of neural and glial processes and pure biological based on cells and thermodynamics and nothing more. What is the best evidence and latest research so far now with regards to this issue? Is there a definite argument for example why biology (or mere calculational methods based on neural networks) is insufficient to produce qualia or internal subjective experience ?
