Personally, I gave up all hopes of unravelling the self-awareness question and put a big-yellow stickey note on it that just read "Impassable Road-Block: No common language." I mean, the Turing Test is a band-aid at best. With more and more sophisticated AI programming, it's becoming easier and easier to make machines that could pass a Turing test because they are programmed to FAKE self-awareness. However, just because they are cleverly designed to FAKE self-awareness does not make them self-aware. And I think the only REAL way to judge self-awareness is to have some kind of language in which a meaningful dialogue can take place. And not even a meaningful dialogue about self-awareness! A meaningful dialogue of ANY type. When it comes to animals, we lack a mutual language and with computers we lack a meaningful mutual language. So... we're still at loggerheads.
