Thank you for the nightmare, now I can go to sleep
I see your point, but IMHO your example is not completely exact. If I ask a person to draw a morkator slagius he will be unable, because he doesn't know what I mean with that. In the same way a human needs a previous experience or at least a proper definition, same comes with the so called AI. I think the major difference between human comprehension and AI one, is that humans don't only work by comparative, they are able to elaborate a response using an intellectual process. But it's surprising how advanced is already all this. It's just matter of time we see an AI able to pass every Turing test.
