Even if you made something that seemed as though it was self-conscious, how would you know if it is really self-conscious or if it is just tricking you into thinking that it is self-conscious?
I could use the same argument against you, how do I know that you really are self-conscious, and not just tricking me by acting like you are? If you think about it, maybe I'm really the only one who is self-couscious, and everyone else just acts like they are, but are really just complicated robots
...but thinking that way too much makes you into a sociopath...
by that token, I would argue that the distinction between Acts conscious, and Is conscious to be pointless, its all relative anyway
