We don't even know if the appearance of self-awareness is all that other humans have. We only know for sure of our own self-awareness, since that is precisely the definition of self-awareness. For all we can prove, the appearance of self-awareness is all that is necessary for consciousness. I could be that if you point a webcam at a computer, then that computer gains some rudimentary self-awareness like an insect might have, or not have, we can't really prove it either way. Sentience is not necessarily sapience. It could also be that computer sentience is absurd and rendered impossible by some as of yet unknown mechanic. In either case we have no reason to make assumptions about it.
