Earlier quoted context omitted.
Note that I carefully used the word "likely". There is no proof. Simply Occam's razor. Why would something that has no consciousness make up that it has consciousness?
> Why would something that has no consciousness make up that it has consciousness? You can make a computer program `printf("I have consciousness\n");` But I actually also didn't follow the rest of the argument. How does whether other people say they have consciousness or not, tell anything about whether it's physics based or not? If it's physics based, people could say they have consciousness. If it's not physics bas…
1. People are talking about consciousness.
2. This talking happens in the physical world (soundwaves are being produced, etc.)
3. We assume that other people have consciousness since they talk about it. As you say, there is no absolute proof of this, but Occam's razor makes it silly to assume otherwise.
4. So, the soundwaves (physics) are happening because of consciousness. There is a causal link from consciousness to physics.
This means that consciousness is not simply the observation of physics. It actually loops back into it, or physics is an emergent property of consciousness.
