Yes as Chambers said "consciousness is the hard problem." I doubt any set of hard ware can ever be made to have even simple experiences ("Qualia") that humans have all the time. However, I think we have them because the brain, specifically the parietal part, is running a real time simulation and creating "us" in the process. I have also suggested that because of this genuine free will is not necessarily inconsistent with the natural laws that control the firing of every nerve in your body. See how I think we have experiences and may even have genuine free will (but I doubt that) at: http://www.sciforums.com/showpost.php?p=905778&postcount=66 BTW, IMHO, John Searle makes the most sense on this subject. SUMMARY: My POV is not that we are living in simulation, but that we are part of a real time parietal (brain) simulation. I.e. "we" are not a physical body, but an informational process. Note "I" ,"we" "us" etc. in quotes refers to this created psychological self not the physical self /body.
