My question to you and all people who talk about the hard problem of consciousness : does this problem actually exist? I mean, the thing I learned when I was a student was to ask: is this a fact? (zero hypothesis I think it was called). What proof do we have that that type of consciousness/experience exists? I mean, It could be our brain building a story on the fly to explain our senses. What led me to believe that is a severe asthma that led to hallucinating and NDE 4 or 5 years ago. The loops my brain made me jump through to explain my auditive hallucinations was terrifying when I think about it. And also it's the simplest explanation.
