Maybe not today, but eventually physics will have to come face to face with the hard question of consciousness. Currently, the prevailing idea is that given enough complexity, an AI machine will attain consciousness. Popular speakers such as Daniel Dennett firmly believe that consciousness is an illusion and hardware (the brain specifically) generate consciousness and as a result consciousness can be considered an "emergent property" of the electro-chemical activity of the brain. This is not justified mathematically, scientifically, or otherwise, so my question is why is this concept "emergent property" taken so seriously. To me it is pure nonsense. My justification for saying this is I know full and well that AI is nothing more than electro-mechanical relays in the form of transistors on silicon (to increase speed and density). There is nothing magical about this. It is purely mechanical. There is absolutely nothing in the way of a theory or a precedent that would allow for "consciouness" (awareness of reality) to come about because a bunch of clacking relays reach some threshold of complexity. So what gives? Why do physicists believe in emergent properties especially with regard to the hard question of consciousness. I could have put this in the general discussion section, but felt it really needs to be addressed at a more profound level. Sorry if its a bit off target.
