. If a computer could demonstrate objectively that it is genuinely thinking about "What am I and who am I and what is my place in the scheme of things?" I would concede defeat. But I have no idea how you might prove or disprove whether it has been achieved or not.

If a computer could demonstrate objectively that it is genuinely thinking about "What am I and who am I and what is my place in the scheme of things?", then it would be definitely superior to any human being. Or did you ever encounter somebody capable of such a feat?
Quite apart from that, there would never be unanimity about the ranking of the machine: one part of humanity would say it is inferior, the other, superior. But "like" humans? You would need 7 billion different machines

BTW I like this thread. Don't let it go down
