With all this consciousness discussion, and consciousness being a purely subjective thing. Please explain why you assume by default that every human actually has a "real consciousness"? How do you substantiate this assumption? And, given mental illnesses, where do you draw the line? Is everyone capable of speech conscious according to your idea of the world? What is the differenece between an LLM and a human stochastic parrott? How would you determine the difference? We are falling for the same error again and again. We consider humans something special, simply because we belong to that group, and would like us to be something special. But given the language barrier to other animals--roughly the same barrier we would have if we'd stumble over aliens--I really think we have pretty much no idea how other living things work and feel.
